Example of embedding Flutter using FlutterView

This project demonstrates how to embed Flutter within an iOS or Android application. On iOS, the iOS and Flutter components are built with Xcode. On Android, the Android and Flutter components are built with Android Studio or gradle.

You can read more about accessing platform and third-party services in Flutter.

iOS

Configure

Create an ios/Flutter/Generated.xcconfig file with this entry:

  • FLUTTER_ROOT=[absolute path to the Flutter SDK]

There are a number of other parameters you can control with this file:

  • FLUTTER_APPLICATION_PATH: The path to the directory that contains your pubspec.yaml file relative to your xcodeproj file.
  • FLUTTER_BUILD_MODE: Whether to build for debug, profile, or release. Defaults to release.
  • FLUTTER_TARGET: The path to your main.dart relative to your pubspec.yaml. Defaults to lib/main.dart.
  • FLUTTER_FRAMEWORK_DIR: The absolute path to the directory that contains Flutter.framework. Defaults to the ios-release version of Flutter.framework in the bin/cache directory of the Flutter SDK.

Build

Once you've configured your project, you can open ios/HelloServices.xcodeproj in Xcode and build the project as usual.

Android

Configure

Create an android/local.properties file with these entries:

  • sdk.dir=[path to the Android SDK]
  • flutter.sdk=[path to the Flutter SDK]

There are a number of other parameters you can control with this file:

  • flutter.buildMode: Whether to build for debug, profile, or release. Defaults to release.
  • flutter.jar: The path to flutter.jar. Defaults to the android-arm-release version of flutter.jar in the bin/cache directory of the Flutter SDK.

See android/app/build.gradle for project specific settings, including:

  • source: The path to the directory that contains your pubspec.yaml file relative to your build.gradle file.
  • target: The path to your main.dart relative to your pubspec.yaml. Defaults to lib/main.dart.

Build

To build directly with gradle, use the following commands:

  • cd android
  • gradle wrapper
  • ./gradlew build

To build with Android Studio, open the android folder in Android Studio and build the project as usual.
