Flutter 本地通知、自定义声音不适用于 iOS

Question

我在我的项目中使用

flutter_local_notifications: 4.0.1+2

。 出现通知我正在尝试在 iOS 上播放自定义声音。” 我尝试按照以下方法为 iOS 实现自定义声音，但它不起作用：

  flutterLocalNotificationsPlugin
  .resolvePlatformSpecificImplementation<
      IOSFlutterLocalNotificationsPlugin>()
  ?.requestPermissions(
    alert: true,
    badge: true,
    sound: true,
  );

  var initializationSettings = InitializationSettings(
  android: initializationSettingsAndroid, iOS: initializationSettingsIOS);
  flutterLocalNotificationsPlugin.initialize(initializationSettings);

  const AndroidNotificationDetails androidPlatformChannelSpecifics =
      AndroidNotificationDetails(
          'Adhan Times Notification', 'Islamic App', 'Allah O Akbar',
          priority: Priority.high,
          sound: RawResourceAndroidNotificationSound('azan'));
  const IOSNotificationDetails iOSPlatformChannelSpecifics =
      IOSNotificationDetails(sound: 'azan.aiff');

azaan.aiff

文件位于

app/ios/Runner

。

如有任何帮助，我们将不胜感激。谢谢

Answer 1

除了

playsound

构造函数的

sound

属性之外，属性

IOSNotificationDetails

也必须设置为 true。

Answer 2

 const DarwinNotificationDetails darwinNotificationDetails =
    DarwinNotificationDetails(sound: 'slow_spring_board.aiff');

    final NotificationDetails notificationDetails = NotificationDetails(
      iOS: darwinNotificationDetails,
      //  linux: linuxPlatformChannelSpecifics,
    );
    await flutterLocalNotificationsPlugin.show(
      id++,
      'custom sound notification title',
      'custom sound notification body',
      notificationDetails,
    );

还可以将声音文件拖放到 xcode 中的 ios 文件夹中

经过几天的故障排除，我已经使用 flutter_local_notifications 包在 Flutter 中成功实现了本地通知。以下是针对可能面临类似挑战的其他人的简明指南和警告。

1. pubspec.yaml：

    environment:
      sdk: '>=2.19.2 <3.0.0'
    dependencies:
      flutter:
        sdk: flutter
      timezone: ^0.9.2
      flutter_local_notifications: ^15.1.0+1
   

2. notification_service.dart：

    class LocalNotificationService {
      final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
      final AndroidInitializationSettings initializationSettingsAndroid = const AndroidInitializationSettings('@mipmap/launcher_icon');
      final DarwinInitializationSettings initializationSettingsDarwin = const DarwinInitializationSettings();
   
      Future<void> showNotification(title, description, route) async {
        // Android Notification Configuration
        AndroidNotificationDetails androidPlatformChannelSpecifics = AndroidNotificationDetails(
          'jbvfbfdjh', // Customize channel id
          'channel_default', // Customize channel title
          channelDescription: 'channel_default',
          playSound: true,
          sound: const RawResourceAndroidNotificationSound('notification_sound'), // Add your sound file WITHOUT file extension (ex.: .mp3, .mp4, etc)
          importance: Importance.max,
          styleInformation: BigPictureStyleInformation(
            const DrawableResourceAndroidBitmap('@mipmap/launcher_icon)'),
            largeIcon: const DrawableResourceAndroidBitmap('@mipmap/launcher_icon'),
            contentTitle: title,
            summaryText: description,
          ),
          enableVibration: true,
        );
   
        // iOS Notification Configuration
        DarwinNotificationDetails iOSPlatformChannelSpecifics = const DarwinNotificationDetails(
          sound: 'notification_sound.caf' // add the sound file name with the extension
        );
   
        NotificationDetails platformChannelSpecifics = NotificationDetails(
          android: androidPlatformChannelSpecifics,
          iOS: iOSPlatformChannelSpecifics
        );
   
        final InitializationSettings initializationSettings = InitializationSettings(
          android: initializationSettingsAndroid,
          iOS: initializationSettingsDarwin
        );
   
        // Show the notification
        await flutterLocalNotificationsPlugin.show(
          0,
          title,
          description,
          platformChannelSpecifics,
          payload: route,
        );
      }
    }
   

警告：

您的通知声音必须放置在两个位置才能在 Android 和 iOS 上正常运行。

对于 Android，请将其放置在

your_flutter_project/android/app/src/main/res/raw/notification_sound.mp3.

对于 iOS，在 XCode 上打开 ios/Runner.xcworkspace 并将声音放在根目录中。

确保您使用适用于 Android (.mp3) 和 iOS (.caf) 的适当文件扩展名。

我希望本指南可以帮助其他在 Flutter 中面临类似本地通知挑战的人。如果您有任何疑问或需要进一步说明，请随时询问！

您可以在主屏幕的 init 方法中调用以下方法

 void _requestPermissions() {
flutterLocalNotificationsPlugin
    .resolvePlatformSpecificImplementation<
        IOSFlutterLocalNotificationsPlugin>()
    ?.requestPermissions(
      alert: true,
      badge: true,
      sound: true,
    );
flutterLocalNotificationsPlugin
    .resolvePlatformSpecificImplementation<
        MacOSFlutterLocalNotificationsPlugin>()
    ?.requestPermissions(
      alert: true,
      badge: true,
      sound: true,
    );
  }
