When I am trying to open a source (url) without the internet on the device (flight mode on), I receive the next logs:

[   +1 ms] flutter: SocketException: Failed host lookup: 'raw.githubusercontent.com' (OS Error: nodename nor servname provided, or not known, errno = 8)

try/catch doesn't help...

Any advice or idea?

UPDATE:

It take me some time to debug example app and compare with mine. The issue comes cos I use headers with my source.

Here is piece of code from library, where dramattic change happened:

  @override
  Future<void> _setup(AudioPlayer player) async {
    await super._setup(player);
    if (uri.scheme == 'asset') {
      _overrideUri = await _loadAsset(uri.pathSegments.join('/'));
    } else if (uri.scheme != 'file' &&
        !kIsWeb &&
        (headers != null || player._userAgent != null)) {
      await player._proxy.ensureRunning();
      _overrideUri = player._proxy.addUriAudioSource(this);
    }
  }

we are interested in this particular line:

        (headers != null || player._userAgent != null)) {

I use headers, so in my app code goes futher, and then fails inside _proxyHandlerForUri, line 3039.
