flutter - 点击通知时 Flutter OneSignal 不打开应用程序

Question

我有 Flutter 应用程序，它可以与 OneSignal 插件一起正常工作，但是我有一个问题，当单击通知时，如果应用程序关闭或在后台运行，我将无法打开应用程序，但是当它在前台打开通知时没有问题。我想在收到通知时打开应用程序，然后单击它。

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  static const String oneSignalAppId = "XXXXXX-XXXXX-XXXXXXX-XXXXXX-XXXXX";

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text("Manchester United"),
        elevation: 0,
      ),
      backgroundColor: Colors.red[200],
      body: const WebView(
        initialUrl: 'https://manchester-united.football/',
        javascriptMode: JavascriptMode.unrestricted,
      ),
    );
  }

  Future<void> initPlatformState() async {
    OneSignal.shared.setAppId(
      oneSignalAppId,
    ); //OneSignal.shared.setInFocusDisplayType(OSNotificationDisplayType.notification);
    OneSignal.shared
        .setNotificationOpenedHandler((OSNotificationOpenedResult result) {
      var data = result.notification.additionalData;

      globals.appNavigator?.currentState?.push(MaterialPageRoute(
        builder: (context) => SecondPage(
          postId: data!["myappurl"].toString(),
        ),
      ));
    });
  }
}
