A docker image that features Android Build Tools, Android SDK, and Flutter. The image is based on cirrusci/android-sdk.
You can specify the version of Android SDK with the build argument ANDROID_VERSION (default: 29) and the version of Flutter with the build argument FLUTTER_VERSION (default: 1.20.2). For example, to run with Android SDK 29 and Flutter 1.22.0-1.0.pre, issue:
docker build --build-arg ANDROID_VERSION=29 --build-arg FLUTTER_VERSION=1.22.0-1.0.pre .
