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,
);
}
}
