Flutter Sound Version : 7.8.4

When play button click flutter app freezes until audio starts playing. This is happening in only Android app, iOS app doesn’t freeze Can anyone provide the solution?

Start Player Code

Future<void> startPlayer(String url) async { try { if (url != null) { await _ChatState.playerModule.startPlayer( fromURI: url, codec: Codec.aacMP4, whenFinished: () { stopPlayer(); }); } } catch (err) { print('error: $err'); } }

Good news 🎉 I’ve managed to solve this problem 😄 Now, the app will not freeze with slow connections or no connection at all.

Now the bad news 😭 If the user does not have an internet connection, the lib will try to download the audio for approximately 40 seconds, the app will not freeze while this time passes, after these 40 seconds the app will go into a stopped state because it could not download. When it enters this state, the user cannot start the player again.

As far as I could figure out, the Lock on line 335 of the tau_sound/lib/public/tau_player.dart file is causing this issue of not letting the player start again.

If the user closes the player and opens it again, he is able to try to start the player again.

Well, anyway, I’m trying to solve this problem too.

OK. You are probably right. I am going to look that.

But just wait a little bit, I am actually busy releasing Flutter_Sound 8.4 and Tau_sound 9.0 (with your PullRequest included 😄 )
