flutter flavorで環境判別

今はflutter Dart-defineで環境判別のほうがよさげ

共通

以下のファイルを作成
lib/flavor.dart

enum FlavorType {
  dev, // 開発環境
  cus, // 検収環境
  prd, // 本番環境
}

class Flavor {
  static Flavor _instance = Flavor._internal(FlavorType.dev);
  final FlavorType type;

  factory Flavor() {
    return _instance;
  }

  factory Flavor.initialize(FlavorType type) {
    _instance = Flavor._internal(type);
    return _instance;
  }

  Flavor._internal(this.type);
}

lib/main/main_dev.dart

import 'package:app/flavor.dart';
import 'package:app/main.dart';

void main() {
  Flavor.initialize(FlavorType.dev);
  startApp();
}

lib/main/main_cus.dart

import 'package:app/flavor.dart';
import 'package:app/main.dart';

void main() {
  Flavor.initialize(FlavorType.cus);
  startApp();
}

lib/main/main_prd.dart

import 'package:app/flavor.dart';
import 'package:app/main.dart';

void main() {
  Flavor.initialize(FlavorType.prd);
  startApp();
}

lib/main.dart

Future<void> startApp() async {
  runApp(<任意の画面Widget>);
}

起動設定を作成

Android

以下を追記
android/app/build.gradle

android {
    flavorDimensions "server"
    productFlavors {
        dev {
            dimension "server"
            applicationIdSuffix ".dev"
        }
        cus {
            dimension "server"
            applicationIdSuffix ".cus"
        }
        prd {
            dimension "server"
        }
    }
}
