Tutorial for adding flutter to your new or existing android app.

Link to tutorial

Let's assume you have an existing Android app at some/path/MyApp, and that you want your Flutter project as a sibling:

cd some/path/ $ flutter create -t module my_flutter 

This creates a some/path/my_flutter/ Flutter module project with some Dart code to get you started and a .android/ hidden subfolder that wraps up the module project in an Android library.

(While not required in what follows, if you so desire, you can build that library using Gradle:

$ cd .android/ $ ./gradlew flutter:assembleDebug 

Include the Flutter module as a sub-project in the host app's settings.gradle:

// MyApp/settings.gradle include ':app' // assumed existing content setBinding(new Binding([gradle: this])) // new evaluate(new File( // new settingsDir.parentFile, // new 'my_flutter/.android/include_flutter.groovy' // new )) // new 

The binding and script evaluation allows the Flutter module to include itself (as :flutter) and any Flutter plugins used by the module (as :package_info, :video_player, etc) in the evaluation context of your settings.gradle.

Introduce an implementation dependency on the Flutter module from your app:

// MyApp/app/build.gradle : dependencies { implementation project(':flutter') : }
