Flutter with firebase_messaging - 如何在權限對話框中自定義消息？

Question

我正在使用 fcm 和 firebase_messaging 向 flutter 應用程序發送推送通知，並希望在執行 FirebaseMessaging().requestNotificationPermissions 時為 ios 遠程通知自定義權限消息。

現在我在下面有權限對話框

如何自定義“”“想向您發送通知”、“通知可能包括警報、聲音和圖標……”和“不允許/允許”？ 有人知道嗎？

和我的代碼

final FirebaseMessaging  _firebaseMessaging = FirebaseMessaging();
await _firebaseMessaging.requestNotificationPermissions(
              const IosNotificationSettings(
                sound: true, badge: true, alert: true));
await _firebaseMessaging.onIosSettingsRegistered.listen((settings) {
              debugPrint('Settings registered: $settings');
          });

這是我的flutter doctor -v結果

提前致謝！

Answer 1

首先更新您的 pubspec.yaml 文件中最新的 firebase 消息傳遞依賴項

firebase_messaging: ^9.1.0

然后創建一個 firebase 消息傳遞實例

final FirebaseMessaging firebaseMessaging = FirebaseMessaging.instance;

然后請求權限

Future initialize(context) async {
if (Platform.isIOS) {
  firebaseMessaging.requestPermission(
    alert: true,
    announcement: false,
    badge: true,
    carPlay: false,
    criticalAlert: false,
    provisional: false,
    sound: true,
  );
} 

}

Answer 2

在我的例子中，我更新了 firebase 依賴項 firebase_messaging: ^10.0.2 並替換

_fcm.requestNotificationPermissions(const IosNotificationSettings())

到

 _fcm.requestPermission(
        alert: true,
        announcement: false,
        badge: true,
        carPlay: false,
        criticalAlert: false,
        provisional: false,
        sound: true,
      );

但我們將不得不改變

_fcm.configure() 

同樣，用下面的代碼改變它。

FirebaseMessaging.onMessage.listen((RemoteMessage message) {
RemoteNotification _notification = message.notification;
AndroidNotification _android = message.notification?.android;
});

問題解決了。
