watch | <E extends keyof Events>(event: E, listener: Events[E]) => EventSubscription | Oui | Calls listener when the system warns that memory runs low. In a
component it stops when the component unmounts; elsewhere the returned
subscription stops it. |
state | ReadonlySignal<State> | Oui | Whether the app is in the foreground. Watched, it follows the platform;
starting to observe reports the state the platform starts from, which
catches a change made in between. Par défaut: AppStateModule.state |
openSettings | () => Promise<void> | Oui | Opens this app's page in the system Settings. Par défaut: AppStateModule.openSettings |
