Flutter Brew

Posted on  by admin

Hey gang, in this Flutter tutorial we'll list all of our brew data on the home screen. Lesson on List View - https://www.youtube.com/watch?v=TdWhYERuv7g&list. Brew update brew install -HEAD usbmuxd brew link usbmuxd brew install -HEAD libimobiledevice brew install ideviceinstaller ios-deploy. Let’s run flutter doctor and you should see in front of iOS tools — develop for iOS devices. Great 🎉 now you can test on an iOS device also. Install VS Code. Let’s complete this step in one command.

Welcome to FlutterFire! 🔥

FlutterFire is a set of Flutter plugins which connect your Flutter application to Firebase.

Prerequisites#

Before getting started, the documentation assumes you are able to create (or have an existing) Flutter project and alsohave an active Firebase project. If you do not meet these prerequisites, follow the links below:

  • Getting Started with Flutter.
  • Create a new Firebase project.

Installation#

Are you migrating your existing project to these new plugins? Please start with the migration guide.

Before any Firebase services can be used, you must first install the firebase_coreplugin, which is responsible for connecting your application to Firebase. Add the plugin to your pubspec.yaml file:

  • Legacy
  • Null safety
flutter:
Flutter Brew
firebase_core:'0.7.0'

Install the plugin by running the following command from the project root:

Platform Setup#

Once installed, Firebase needs to be configured to work with the various platforms you're working with:

  1. Android Installation.
  2. iOS Installation.
  3. MacOS Installation.
  4. Web Installation.

Initializing FlutterFire#

Before any of the Firebase services can be used, FlutterFire needs to be initialized (you can think of this process asFlutterFire 'bootstrapping' itself). The initialization step is asynchronous, meaning you'll need to prevent any FlutterFirerelated usage until the initialization is completed.

To initialize FlutterFire, call the initializeApp method on the Firebase class:

The method is asynchronous and returns a Future, soyou need to ensure it has completed before displaying your main application. The examples below show how this can beachieved with a FutureBuilder ora StatefulWidget:

  • FutureBuilder
  • StatefulWidget
import 'package:firebase_core/firebase_core.dart';
void main() {
Flutter
runApp(App());
// Create the initialization Future outside of `build`:
final Future<FirebaseApp> _initialization = Firebase.initializeApp();
@override
return FutureBuilder(
future: _initialization,
// Check for errors
return SomethingWentWrong();
if (snapshot.connectionState ConnectionState.done) {
}
// Otherwise, show something whilst waiting for initialization to complete
},
}

Once initialized, you're ready to get started using FlutterFire!

Improve iOS Build Times#

Currently the Firestore iOS SDK depends on some 500k lines of mostly C++ code which can take upwards of 5 minutes to build in XCode. To reduce build times significantly, you can use a pre-compiled version by adding 1 line to your ios/Podfile inside your Flutter project;

pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '7.3.0'

Add this line inside your target 'Runner' do block in your Podfile, e.g.:

target 'Runner' do
pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '7.3.0'
end

Additionally, ensure that you have upgraded your cocoapods to 1.9.1 or higher:gem install cocoapods

For more information see this issue: https://github.com/FirebaseExtended/flutterfire/issues/2751

Overriding Native SDK Versions#

FlutterFire internally sets the versions of the native SDKs that each module uses. Each release is tested against a fixedset of SDK version to ensure everything works as expected.

If you wish to change these versions, you can manually override the native SDK versions

Android#

In the /android/app/build.gradle file, you can provide your own versions using the options shown below:

Flutter Brew

set('FlutterFire', [
])

iOS/MacOS#

Open your /ios/Podfile or /macos/Podfile file and add any of the globals below to the top of the file:

$FirebaseSDKVersion = '6.33.0'

Next Steps#

Flutter Brew Contest

On its own the firebase_core plugin provides basic functionality for usage with Firebase. FlutterFire is broken downinto several individual installable plugins that allow you to integrate with a specific Firebase service.

The table below lists all of the currently supported plugins. You can follow the documentation for each plugin toget started:
