Flutter Riverpod 在生命周期恢复从服务器获取数据

Question

使用下面的代码，我试图在Flutter生命周期恢复时从服务器获取数据，但它对我不起作用，我不知道如何解决这个问题

class Home extends HookConsumerWidget {
  const Home({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    final scaffoldKey = useMemoized(() => GlobalKey<ScaffoldState>());
    final appLifecycleState = useAppLifecycleState();
    final showLoading = useState(false);

    useEffect(() {
      ref.read(bakersProvider.notifier).send(
        method: HTTP.GET,
        endPoint: Server.$onlineBakersList,
        parameters: {},
      );
      if (appLifecycleState == AppLifecycleState.resumed) {
        debugPrint('resumed');
        ref.read(bakersProvider.notifier).send(
          method: HTTP.GET,
          endPoint: Server.$onlineBakersList,
          parameters: {},
        );
      }

      return (){};
    }, [appLifecycleState]);

这个问题解决了。 参考

useOnAppLifecycleStateChange((pref, state) {
  if (state == AppLifecycleState.resumed) {
    //make a request
  }
});
