Fixed it by encoding the url before passing it to the player

final encodedURL = Uri.encodeFull(url);
await player.play(UrlSource(encodedURL));

Maybe the encoding in https://github.com/bluefireteam/audioplayers/blob/audioplayers-v5.2.0/packages/audioplayers/lib/src/uri_ext.dart has to be fixed. Thanks to @cice for debugging this

to give some context: it took us quite a bit of debugging to figure this out. first of all we had to dig deep into the swift/ios part of the player to get some more details on the error (imho the completeError call back should pass on some more details to flutter about the underlying error). inspecting the playerItem on this level revealed an Error containing ultimately the hint "400 Bad Request". Which was strange, because the URL itself worked fine (in any browser/curl/whatever). Upon inspecting the URL down there, we could see that this was not the same URL as we passed in. The thing is, we use Google Storage with signed URLs. The signature is URL-encoded Base64 as a query param. This param gets mangled by audioplayers encodeOnce thingy (see https://github.com/bluefireteam/audioplayers/blob/01193785508abd717b060875cd79eba044910d86/packages/audioplayers/lib/src/uri_ext.dart#L2). I am not sure what was intended to solve here, but the net effect is, that this de- and re-encoding messes up URLs that have encoded query params. Thus our workaround to encode the entire URL once more, so that decodeFull withing encodeOnce effectively does the exact reverse, and the player gets a proper and working URL.

So as a workaround for anyone experiencing something similar is pretty straightforward, but imho the encodeOnce method should be fixed.

@tiloman, see https://github.com/bluefireteam/audioplayers/issues/1669. Reading from the issue description and url, this problem has nothing to do with encoding.

me to.

The error seen in sentry background is on ios

I had to switch from

player.setSourceUrl() --> player.setSourceDeviceFile()

Seeing as I am playing from a recorded file.
