Correct code for notification sound in FCM not clear.

[eeerrrttty]

      let message = {
        // notification: {
        //   title: 'Chamada de serviço',
        //   body: `R$ ${(snap.after.data().workDoing.priceCents / 100)}`
        // },
        data : {
          priority: '2',
          messageType: 'data',
          android_channel_id: 'fcm_divas_channel',
          notification_android_channel_id: 'fcm_divas_channel',
          title : 'Chamada de serviço',
          body: `R$ ${(snap.after.data().workDoing.priceCents / 100)}`,
          sound: 'divas',
          notification_title: 'Chamada de serviço',
          notification_body: `R$ ${(snap.after.data().workDoing.priceCents / 100)}`,
          notification_android_sound: 'divas',
          notification_android_priority: '2',
          notification_android_visibility: '1',
          notification_android_vibrate: '8000, 200',
          vibrate: '8000, 200',
          visibility: '1',
          notification_foreground: 'true',
          show_notification: 'true'
        },
        android: {
          collapse_key: 'a',
          priority: 'high',
          ttl: '3600s',
          notification: {
            channel_id: 'fcm_divas_channel',
            sound: 'divas',
            priority:'high'
          }
        },
        // data : {
        //   notification_android_sound: 'divas_sound'
        // },
        // data: {
        //   message: '',
        //   type: 'Call'
        // },
        token: snap.after.data().fcmToken
      }

My code:

            let channel = {
              id: 'fcm_divas_channel',
              sound: 'divas',
              vibration: [8000, 200],
              visibility: 1
            }
            window.FirebasePlugin.createChannel(channel,
              function () {
                console.log('Channel created: ' + channel.id)
              },
              function (error) {
                console.log('Set default channel error: ' + error)
              })

Why my custom sounds doesn't come to users ? I putted the correct sound divas.mp3 on my res/raw with config.xml parameters as documentation

FWIW, apparently the channel_id must be unique for each sound, whether or not you delete the channel before calling createChannel(). Apparently Firebase maintains all previously defined channel_id's, and any attempt to change the sound for an existing id is simply ignored.

NOTE: I found this by adding the sound to what listChannels() returns (it was previously returning only id & name). Once I realized that I couldn't update a sound I made sure that my channel IDs were a hash of the underlying settings in order to avoid this in the future. Things worked much better after that.

@eeerrrttty Please build and run the example project to verify that custom sounds are working and as a reference for how to implement in your own project.

@grumpygary Thanks for clarifying this - it's not clear from the Firebase SDK documentation.
I've added a note to the plugin documentation for createChannel().
