flutter_mobile_app_template

Templates for mobile app projects using flutter.
The environment variable --dart-define=OPERATION_TYPE at build time switches firebase project, api connecting destination, and others.

• Firebase configuration file is empty, so overwrite the files under android/app/firebase and under ios/firebase.

Switching operating environment

In case of Android, switch settings by the script in android/app/build.gradle. In case of iOS, execute ios/Scripts/dart_define.sh from Xcode script execution settings, and change the xcconfig file according to your environment.

OPERATION_TYPE

product, staging, review, develop

• Separate app name, ID, and Firebase configuration files for product and others
• In settings other than product, the id is suffixed with .dev.

Application architecture

ViewModel

UseCase

Repository

Unit test

The .di constructor defined for testing is used to increase testability.

@visibleForTesting
SampleClass.di(this._sample);

flutter pub run build_runner build --delete-conflicting-outputs
