volume control is not working

[tarekbazine]

once I call setVolume() I get this error :

i've got no error like that but it cannot set the volume

The reason: the Kotlin implementation misses the setVolume method! So, on Android, it Wont' work, the missing plugin exception will occure. Btw, on iOS, implementation seems to me o.k.

So, what can be done for android? Until the plugin owner does not correct this BUG, then, you can workaround it, from other words, you can solve it locally, in this way:

0. download flutter_radio from github, and use this as local plugin In pubspec.yaml, write

   flutter_radio: 
   path: ../flutter_radio

   if the directory of flutter_radio is next to the directory of your project.

1. open FlutterRadioPlugin.kt, goto onMethodCall add an else branch here:

   call.method.equals("setVolume")-> {
         val volume = call.argument("volume") as Double
         radioManager.setVolume(volume.toFloat())
         result.success(null)
   }

2. open RadioManager.kt, add:

   fun setVolume(volume: Float) {
       service.setVolume(volume)
   }

3. open RadioService.kt, add:

   fun setVolume(volume: Float) {
       exoPlayer.volume = volume
   }

That's all. Enjoy it! Cheers, DaneeD
