download firestore framework Flutter: CRUD operations using Cloud Firestore. Cloud Firestore provides you an easily manageable pre-configured NoSQL database. It helps in storing & syncing data for both client and server- side development; it also supports automatic caching of data for using it even offline. Cloud is the driving platform behind Cloud Firestore that can be scaled easily. In this article, you will learn to integrate Cloud Firestore with Flutter , and perform CRUD (create, read, update and delete) operations. So, let’s get started. Creating a Firebase project. You will need to create a new Firebase project in order to integrate it with your application. Navigate to the Firebase console and click Add project . Enter a project name and click Continue . You’ll be asked whether you want to enable Google Analytics for the project. We won’t need analytics since this is just a sample project, just click Create project . If you do want to enable Google Analytics, you’ll be prompted on the next screen to select a Google Analytics account: Wait for the project to be created, and you’ll be navigated to the project’s Firebase dashboard. Integrating Firebase with Android, iOS, and web. Though we’re using Flutter, which is a cross-platform framework, we still need to integrate the Firebase project separately for each platform. Flutter 2.0 has support for Android, iOS, and web in its stable channel, so we’ll configure Firebase for all three platforms. Android configuration. Let’s start by configuring for the Android platform. Select the Android icon from the Firebase dashboard. Enter the Android package name, an app nickname, and the SHA-1. Click on Register app . Download the google-services.json file and place it in the android → app directory. Click on Next . Just follow the instructions provided, and add the required code snippets to your project. Click on Next . You have successfully configured Firebase for Android. On the final step, click on Continue to console to go back to the dashboard. iOS configuration. Follow the steps below to complete the configuration on the iOS platform. Select the iOS icon on the dashboard. Download the GoogleService-Info.plist file. Click on Next . Now, open the ios folder using Xcode, drag & drop the file that you downloaded into the Runner subfolder. When a dialog box appears, make sure that Runner is selected in the "Add to targets" box. Then click Finish . You can skip steps 3 and 4, as they are automatically configured by the Flutter Firebase plugin that we will be adding soon. Click on Continue to console to go back to the dashboard. Web configuration. Configure the Firebase project for the web by following the steps given below. Select the Web icon on the dashboard. Enter the app nickname and click on Register app . Now, add the code snippets for integrating the Firebase SDK into the web app. Then, click on Continue to console to navigate back to the dashboard. Finally, you have completed the Firebase configuration for all the three platforms. Getting started. Let’s take a look at the sample project that we will be building, and then start integrating Cloud Firestore with the Flutter app. Project overview. We will be building a simple notes management app where you can see the list of saved notes, save new notes, and also update & delete them. This sample app will consist of four screens; the first one will be a very simple login screen for authenticating a user. But as the main focus of this article is the database, we won’t go and set up a full-fledged authentication logic. The login screen will simply accept a unique identifier which can be later used to customize and store data privately for each user. The other three screens will be a DashboardScreen (displaying the list of notes), AddScreen (for adding a new note item), and EditScreen (for editing an already saved note item). Enabling Cloud Firestore. You can enable the Firestore database by selecting Firestore from the left menu and then clicking on Create database . Now, you will be prompted to select a type of security rule. Here, we will choose test mode (that is, the database is open to all and it doesn’t check for any kind of authentication) because we will not set up any kind of strict authentication for this sample app. Click on Next . If you are working on a production app, make sure you define an appropriate security rule. You can learn more here . Then, you have to select a Cloud Firestore location and click on Enable . You will be taken to an empty Firestore database structure. We will start adding data to the database using the Flutter app. Creating a Flutter project. You can create a new Flutter project using the following command: Then open the project using your favorite code editor. For opening with VS Code you can use: Flutter 2.0 has support for null safety in the stable channel, but in order to use it inside the app, you have to run a command for migrating the project to null safety. Before running the migration command, check if all your current project dependencies support null safety by using: Then, run the following command to migrate: Adding Firebase to Flutter. We will be using the following plugins in this project: : Required for initializing Firebase and using any other Firebase plugins. : Required for interacting with the Firestore database. The latest version of both these plugins support null safety . Add these to your pubspec.yaml file: Install the packages from the command line using: Go to your main.dart file present in the lib folder of the root directory. Replace the contents with the following: LoginScreen will be a StatefulWidget . Define a method inside it called _initializeFirebase() that will initialize the firebaseApp . Inside a FutureBuilder call the _initializeFirebase() method which will show the LoginForm widget as the initialization is complete. Before moving on further with the UI, let’s take a look at how the Firestore database is structured, and then define methods for performing the CRUD operations. Understanding Firebase structure. It's important to understand how data is structured in the Firestore database before we start defining our CRUD methods. Cloud Firestore mainly consists of collections , documents, and fields (key-value pairs). Collections can contain a number of documents , which in turn can consist of sub-collections and key-value pairs. References are used for pointing to a particular location in the database, that information can be used for storing, retrieving, updating, and deleting data from the database.

Precompiled Firestore iOS SDK xcframework files extracted from the Firebase iOS SDK repository release downloads, tagged by Firebase iOS SDK version and presented as a consumable podspec . Currently the Firestore iOS SDK depends on some 500k lines of mostly ++, which when compiling as part of your Xcode build takes a long time - even more so in CI environments. Related Issues. Adding FirebaseFirestore pod dependency adds minutes to build time [cloud_firestore] Xcode build extremely slow. Before and after timing below, timed when running Xcode build (with cache fully cleared) in a project with Firestore. Mac mini (2018) 6 cores : GitHub Action CI 2 cores : Integrating is as simple as adding 1 line to your main target in your projects Podfile . Any dependencies in your project that already consume the Firebase iOS SDK from pods will then automatically source Firestore from these precompiled binaries rather than from source. For Flutter & this file is usually located at ios/Podfile For Futter the target is usually called Runner and can be added inside the target 'Runner' do block in your podfile. For React Native this would be inside the target that has all your local React-* pods included. Note: where the tag says 7.11.0 this should be changed to the pod version of Firebase/Firestore that you or your dependencies are using - in the format X.X.X , for FlutterFire the version that is being used can be seen here, for React Native Firebase here. If no version is specified on your current Firebase/Firestore pod then you can omit , :tag => '7.11.0' from the line above and use the latest version on master. The first time you pod install a specific version, CocoaPods will remotely retrieve this git repository at the specifed tag and cache it locally for use as a source for the FirebaseFirestore pod. Note: if you were previously caching iOS builds on CI you may now find that when using precompiled binaries that caching is no longer required and it may actually slow down your build times by several minutes. Resolving '' missing or duplicate symbol errors. The "leveldb" framework is needed by FirebaseFirestore but may be included in other libraries, so it needs to be included or excluded correctly. The podspec here attempts to do that for you automatically by default, by detecting known situations where it should be excluded, but sometimes auto-detection fails. If your build fails due with duplicate 'leveldb' symbols, pod FirebaseFirestore/WithoutLeveldb as the pod name instead of pod FirebaseFirestore , reinstall pods and try rebuilding. If your build fails due with missing 'leveldb' symbols, pod FirebaseFirestore/WithLeveldb as the pod name instead of pod FirebaseFirestore , reinstall pods and try rebuilding. Supported Firebase iOS SDK versions. The below are the currently supported Firebase iOS SDK versions of this repository, this list is updated automatically. Note: if you are looking for a new version that is not listed in the supported versions list, examine the upstream release notes for firebase-ios- sdk carefully. This can happen if the firebase-ios-sdk team issues an interim release to solve some urgent problem, but do not run their full release process. If that happens, don't worry - just wait for the next supported version before moving forward, or temporarily de-integrate this pre- compiled framework if you must use the interim version. 6.31.1 is an example of this, with more details here for why it might happen.

I make one hybride app for IOS . I use Framework7 with Cordova. If I use only Cordova, it can reach my firestore. But if I use Cordova + Framework7 CLI, it can't see firestore. In Xcode, I see this fault. @firebase/firestore: Firestore (7.8.2): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds. This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend. Here is some screenshots. What is problem? Can you help, please ? 1 Answer 1. One of Firestore Developers indicates in this Github Thread that this might be a very common error to occur. As he mentions here: your problem might be related to your browser throttling the page when it's in a background tab, causing our Firestore connection to time out. This means that something on your environment might be affecting your connection to Firestore, causing the error that you are facing. In this post from the Community - @firebase/firestore: Firestore (5.0.4): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds, it's indicated some possible solutions that I think might help you, since your case seems to be the same as of them - even though they are using another language, which should not be the problem. I would recommend you to try following the below steps: Open the Firebase Console, open or create a new project. In the Database section, click the Get Started button for Cloud Firestore . Select a starting mode for your Cloud Firestore Security Rules: Test mode or Locked mode. Another option, would be to check any antvirus or firewall that might be blocking your application to access Firestore in the backend. Besides that, if even after all of these steps and tests you are still facing the issue, I would recommend you to reach out to the Firebase/Firestore Support directly. They have some free options to contact them and since they are the direct developers, I believe they should be able to investigate further in case it's needed. Download firestore framework ios. In this codelab you will build a Firestore-backed restaurant recommendation app on iOS in Swift. You will learn how to: Read and write data to Firestore from an iOS app Listen to changes in Firestore data in realtime Use Firebase Authentication and security rules to secure Firestore data Write complex Firestore queries. Prerequisites. Before starting this codelab make sure you have installed: Xcode version 8.3 (or higher) CocoaPods 1.2.1 (or higher) Add Firebase to the project. Go to the Firebase console. Select Create New Project and name your project "Firestore iOS Codelab". Download the Code. Begin by cloning the sample project and running pod update in the project directory: Open FriendlyEats.xcworkspace in Xcode and run it (Cmd+R). The app should compile correctly and immediately crash on launch, since it's missing a GoogleService-Info.plist file . We'll correct that in the next step. Set up Firebase. Follow the documentation to create a new Firestore project. Once you've got your project, download your project's GoogleService-Info.plist file from Firebase console and drag it to the root of the Xcode project. Run the project again to make sure the app configures correctly and no longer crashes on launch. After logging in, you should see a blank screen like the example below. If you're unable to log in, make sure you've enabled the Email/Password sign-in method in Firebase console under Authentication. In this section we'll write some data to Firestore so that we can populate the app UI. This can be done manually via the Firebase console, but we'll do it in the app itself to demonstrate a basic Firestore write. The main model object in our app is a restaurant. Firestore data is split into documents, collections, and subcollections. We will store each restaurant as a document in a top-level collection called "restaurants" . If you'd like to learn more about the Firestore data model, read about documents and collections in the documentation. Before we can add data to Firestore, we need to get a reference to the restaurants collection. Add the following to the inner for loop in the RestaurantsTableViewController.didTapPopulateButton(_:) method. Now that we have a collection reference we can write some data. Add the following just after the last line of code we added: The code above adds a new document to the restaurants collection. The document data comes from a dictionary, which we get from a Restaurant struct. Note : Firestore uses dictionaries and other Foundation data types, but it's best practice in Swift when representing data to use a value type with stronger guarantees than Dictionary. Take a look at Restaurant.swift for the implementations of these value types. We're almost there--before we can write documents to Firestore we need to open up Firestore's security rules and describe which parts of our database should be writeable by which users. For now, we'll allow only authenticated users to read and write to the entire database. This is a little too permissive for a production app, but during the app-building process we want something relaxed enough so we won't constantly run into authentication issues while experimenting. At the end of this codelab we'll talk about how to harden your security rules and limit the possibility of unintended reads and writes. Open the Firebase console and navigate to Database > Rules in the Firestore tab. The default rules prevent any reads or writes in the database from any user. Replace the defaults with the following rules. We'll discuss security rules in detail later, but if you're in a hurry, take a look at the security rules documentation. Run the app and sign in. Then tap the " Populate " button in the upper left, which will create a batch of restaurant documents, although you won't yet see this in the app. Next, navigate to the Firestore data tab in the Firebase console. You should now see new entries in the restaurants collection: Congratulations, you have just written data to Firestore from an iOS app! In the next section you'll learn how to retrieve data from Firestore and display it in the app. In this section you will learn how to retrieve data from Firestore and display it in the app. The two key steps are creating a query and adding a snapshot listener. This listener will be notified of all existing data that matches the query and receive updates in real time. First, let's construct the query that will serve the default, unfiltered list of restaurants. Take a look at the implementation of RestaurantsTableViewController.baseQuery() : This query retrieves up to 50 restaurants of the top-level collection named "restaurants". Now that we have a query, we need to attach a snapshot listener to load data from Firestore into our app. Add the following code to the RestaurantsTableViewController.observeQuery() method just after the call to stopObserving() . The code above downloads collection from Firestore and stores it in an array locally. The addSnapshotListener(_:) call adds a snapshot listener to the query that will update the view controller every time the data changes on the server. We get updates automatically and don't have to manually push changes. Remember, this snapshot listener can be invoked at any time as the result of a server-side change so it's important that our app can handle changes. Note : It is also possible to fetch documents from Firestore once, rather than listening for real time updates, using the Query.getDocuments(completion:) method. After mapping our dictionaries to structs (see Restaurant.swift ), displaying the data is just a matter of assigning a few view properties. Add the following lines to RestaurantTableViewCell.populate(restaurant:) in RestaurantsTableViewController.swift . This populate method is called from the table view data source's tableView(_:cellForRowAtIndexPath:) method, which takes care of mapping the collection of value types from before to the individual table view cells. Run the app again and verify that the restaurants we saw earlier in console are now visible on the simulator or device. If you completed this section successfully your app is now reading and writing data with Cloud Firestore! Currently our app displays a list of restaurants, but there is no way for the user to filter based on their needs. In this section you will use Firestore's advanced querying to enable filtering. Here's an example of a simple query to fetch all Dim Sum restaurants: As its name implies, the whereField(_:isEqualTo:) method will make our query download only members of the collection whose fields meet the restrictions we set. In this case, it'll only download restaurants where category is "Dim Sum" . In this app the user can chain multiple filters to create specific queries, like "Pizza in San Francisco" or "Seafood in Los Angeles ordered by Popularity". Open RestaurantsTableViewController.swift and add the following code block to the middle of query(withCategory:city:price:sortBy:) : The snippet above adds multiple whereField and order clauses to build a single compound query based on user input. Now our query will only return restaurants that match the user's requirements. Run your project and verify you can filter by price, city, and category (make sure to type the category and city names exactly). While testing you may see errors in your logs that look like this: This is because Firestore requires indexes for most compound queries. Requiring indexes on queries keeps Firestore fast at scale. Opening the link from the error message will automatically open the index creation UI in the Firebase console with the correct parameters filled in. To learn more about indexes in Firestore, visit the documentation. In this section, we'll add the ability for users to submit reviews to restaurants. Thus far, all of our writes have been atomic and relatively simple. If any of them errored, we'd likely just prompt the user to retry them or retry them automatically. In order to add a rating to a restaurant we need to coordinate multiple reads and writes. First the review itself has to be submitted, and then the restaurant's rating count and average rating need to be updated. If one of these fails but not the other, we're left in an inconsistent state where the data in one part of our database doesn't match the data in another. Fortunately, Firestore provides transaction functionality that lets us perform multiple reads and writes in a single atomic operation, ensuring that our data remains consistent. Note : Transactions are appropriate for complex write operations that also require intermediate reads. If you're just looking to write a bunch of documents at once and don't need to worry about intermediate reads or operation order, you should use FIRWriteBatch instead. Add the following code below all the let declarations in RestaurantDetailViewController.reviewController(_:didSubmitFormWithReview:) . Inside of the update block, all the operations we make using the transaction object will be treated as a single atomic update by Firestore. If the update fails on the server, Firestore will automatically retry it a few times. This means that our error condition is most likely a single error occurring repeatedly, for example if the device is completely offline or the user isn't authorized to write to the path they're trying to write to. Note : When a transaction fails on the server, the update block is also re-executed on each retry. Avoid placing logic that modifies app state inside the update block. Users of our app should not be able to read and write every piece of data in our database. For example everyone should be able to see a restaurant's ratings, but only an authenticated user should be allowed to post a rating. It's not sufficient to write good code on the client, we need to specify our data security model on the backend to be completely secure. In this section we'll learn how to use Firebase security rules to protect our data. First, let's take a deeper look at the security rules we wrote at the start of the codelab. Open the Firebase console and navigate to Database > Rules in the Firestore tab. The request variable in the rules above is global variable available in all rules, and the conditional we added just ensures that the request is authenticated before allowing it to do anything. This prevents unauthenticated users from using the Firestore API to make unauthorized changes to your data. This is a good start, but we can use Firestore rules to do much more powerful things. Let's restrict review writes so that the review's user ID must match the ID of the authenticated user. This ensures that users can't impersonate each other and leave fraudulent reviews. Replace your security rules with the following: The first match statement matches the subcollection named ratings of any document belonging to the restaurants collection. The allow write conditional then prevents any review from being submitted if the review's user ID doesn't match that of the user. The second match statement allows any authenticated user to read and write restaurants to the database. This works really well for our reviews, as we've used security rules to explicitly state the implicit guarantee we wrote into our app earlier--that users can only write their own reviews. If we were to add an edit or delete function for reviews, this exact same set of rules would also prevent users from modifying or deleting other users' reviews as well. But Firestore rules can also be used in a more granular fashion to limit writes on individual fields within documents rather than the whole documents themselves. We can use this to allow users to update only the ratings, average rating, and the number of ratings for a restaurant, removing the possibility of a malicious user altering a restaurant name or location. Here we've split up our write permission into create and update so we can be more specific about which operations should be permitted. Any user can write restaurants to the database, preserving the functionality of the Populate button we made at the start of the codelab, but once a restaurant is written its name, location, price, and category cannot be changed. More specifically, the last rule requires any restaurant update operation to maintain the same name, city, price, and category of the already existing fields in the database. To learn more about what you can do with security rules, take a look at the documentation. In this codelab, you learned how to basic and advanced reads and writes with Firestore, as well as how to secure data access with security rules. You can find the full solution on the codelab-complete branch.
