Hi, thank you for your work. I'm trying to use the library on Android but i'm getting error on building phase:

FAILURE: Build failed with an exception.**

On IOS device no problems.

Can you help me with this? Thanks

Its perfectly working in Android device

I am adding issue below with complete description.

Hello, in your example I saw that your package makes it possible to get the current Artist and Song but both things are displayed in one TextWidget with snapshot.data.

Is it possible to show Artist and Song in different Text Widgets?

Do your package also provides the ability to show the album cover or the album name or the song length?

Only at the first start of the radio, the status of the button is play but should be paused. Music is playing and show play button.

After press on play button the status of the button get correct.

Tested with: ios iphone X 13.3.1

Hello, how are you? I am interested in using the flutter_radio_player, I am using the Android studio to run the example code, but this is giving an error, I have already researched the solution for this error and so far I have not found it. Do you have any suggestions to resolve this error below I thank you for your help Samuel flutter_radio_player.txt

and a bunch more, Could you please help me with this?

Hello,

I have tested with internet events, when i switched off the internet it shows the flutter_radio_paused event, and on resume internet is turned into flutter_radio_loading and then nothing happened. Then on click of play button also nothing happened.

Please help with internet events, player should play/pause as per connectivity conditions.

Test project is the same library example.

Thanks

I realised that the album art does not update on Android 13 in version 1.0.1. After a little digging, I found that the getCurrentLargeIcon method in the RadioPlayerService.kt always returns the defaultArtwork as seen below

override fun getCurrentLargeIcon(player: Player, callback: BitmapCallback): Bitmap? {
                metadataArtwork = downloadImage(currentMetadata?.get(2))

                metadataArtwork?.let { callback.onBitmap(it) }
                return  defaultArtwork;
       }

Changing it to the following solves the problem

override fun getCurrentLargeIcon(player: Player, callback: BitmapCallback): Bitmap? {
                metadataArtwork = downloadImage(currentMetadata?.get(2))

                metadataArtwork?.let { callback.onBitmap(it) }
                return if(metadataArtwork == null) defaultArtwork else metadataArtwork;
            }
