Using Android Studio

The Android Studio IDE is a convenient way of integrating
your Flutter module automatically. With Android Studio,
you can co-edit both your Android code and your Flutter code
in the same project. You can also continue to use your normal
IntelliJ Flutter plugin functionalities such as Dart code
completion, hot reload, and widget inspector.
