Flutter 2.0 - 未为“FirebaseMessaging”类型定义“configure”方法

Question

我是扑的新手。我刚刚将一个为我构建的项目升级到 flutter 2.0，我不确定如何解决这个特定问题。我用谷歌搜索并找到了例子。我知道这里有改进，可能会解决我的应用程序面临的问题之一。但我不知道如何调整这个特定的代码部分，因为它比我在网上找到的任何例子都要复杂。希望有人能指出我正确的方向。

void initFCMNotification() {
    _firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        mapEntry = message;
        String type =
            message['Notificationtype'] ?? message['data']['Notificationtype'];
        print("notification onMessage $type");

        if (type == '5' || type == '11' || type == '3') {
          Function reload = context.read<EventsProvider>().reload;
          Future.delayed(Duration(seconds: 1), () {
            reload(true);
          });
        } else if (type == '4') {
          var notification = getNotification(message);
          nav.currentState.push(MaterialPageRoute(
              builder: (context) => MeetAgainScreen(notification)));
        }
        if (type != '11') {
          if (Platform.isIOS) {
            notiType = message['Notificationtype'];
            print('isIOS on message ${message['aps']['alert']['title']}');
            if (type == "0") {
              reloadData(type, message);
            } else {
              showSilentNotification(flutterLocalNotificationsPlugin,
                  title:
                      "${message['title'] ?? message['aps']['alert']['title'] ?? message['notification']['title'] ?? ''}",
                  payload: "${message['Notificationtype'] ?? ''}",
                  body:
                      "${message['body'] ?? message['aps']['alert']['body'] ?? message['notification']['body'] ?? ''}",
                  id: 1);
            }
          } else if (Platform.isAndroid) {
            notiType = message['data']['Notificationtype'];

            print('Android on message /*${message['data']['body']}*/');
            if (type == "0") {
              reloadData(type, message);
            } else {
              showSilentNotification(flutterLocalNotificationsPlugin,
                  title:
                      "${message['data']['title'] ?? message['notification']['title'] ?? ''}",
                  payload: "${message['data']['Notificationtype'] ?? ''}",
                  body:
                      "${message['data']['body'] ?? message['notification']['body'] ?? ''}",
                  id: 1);
            }
          }
        }

从版本 8.0.0-dev.1 开始，configure()已被删除以支持调用返回Streams.

您应该使用FirebaseMessaging.onMessage(),FirebaseMessaging.onMessageOpenedApp()代替。

这里的例子

FirebaseMessaging.onMessage.listen((RemoteMessage message) {
        ...
});
