Firebase push notification with custom sound (Flutter)

Question

I'm currently using firebase messaging cloud to push notification for my app. I'm trying to make a custom notification sound for the push notification. I believe that it can be done by putting "sound: blabla.mp3" inside the payload, but how do i define the sound inside dart page?

Answer 1

It can be done flutter_local_notifications plugin.

First, you should define channels for both Android and iOS:

const androidPlatformChannel = AndroidNotificationDetails(
  'ANDROID_CHANNEL_ID',
  'Name',
  'Description',
  color: Color.fromARGB(255, 0, 0, 0),
  importance: Importance.max,
  sound: RawResourceAndroidNotificationSound('notification_sound'),
  playSound: true,
  priority: Priority.high,
  showWhen: false,
);

const iOSPlatformChannel = IOSNotificationDetails(
  sound: 'notification_sound.aiff',
  presentAlert: true,
  presentBadge: true,
  presentSound: true,
);

const platformChannel = NotificationDetails(
  android: androidPlatformChannel,
  iOS: iOSPlatformChannel,
);

Then show a notification:

await flutterLocalNotificationsPlugin.show(
      id,
      title,
      body,
      platformChannel,
      payload: notification.payload,
    );

IMPORTANT! notification_sound.aiff file should be copied with XCode

Answer 2

Use flutter_local_notifications package

AndroidNotificationDetails androidNotificationsDetails = AndroidNotificationDetails(
       'your other channel id',
       'your other channel name',
       'your other channel description',
        importance: Importance.Max,
        priority: Priority.Max,
        enableLights: true,
        playSound: true,
        sound: RawResourceAndroidNotificationSound('notification'),
);

Note: you should add notification.mp3 file in android/app/src/main/res/raw/notification.mp3 and don't forget to specify playSound:

playSound: true,

this worked for me in the foreground / background and when the app is closed.
