AppScopedValueOrAppRef class abstract

AppRef or AppScopedValueRef to store state in App scope.

This can be extended with an extension to add a method to handle Ref that stores the value for each app.

Appスコープで状態を保存するAppRefもしくはAppScopedValueRef。

これをextensionで拡張することでアプリごとに値を保存するRefを扱うメソッドを追加することができます。

extension RefWatchExtensions on AppScopedValueOrAppRef {
  T watch<T extends Listenable>(
    T Function() callback, {
    List<Object> keys = const [],
  }) {
    return getScopedValue<T, _WatchValue<T>>(
      () => _WatchValue<T>(callback: callback, keys: keys),
      listen: true,
    );
  }
}
