Description

When trying to open a bad mp3 file, the app crashes (no exception — just immediate crash).

Steps To Reproduce

  1. Create a file that's not an mp3. For example, download this PNG and rename its extension to .mp3.
  2. Open the flutter_soloud example app
  3. Switch to the 'hello world!' tab
  4. Click 'pick audio'
  5. Use the file picker to select the invalid mp3 file.
  6. Witness the crash

Expected Behavior

An exception is thrown (or some kind of FlutterErrors thing is returned).

This seems to be related to the StreamController I wrongly used here
When you switch from "waveforms" tab to the "Hello World!", that stream is still active and when it receives a new event, it will try to call SoloudTools.initSounds() which throws that exception!
If you start with the "Hello World!" (initialIndex: 0), this doesn't happen.

So, there are 2 fixes to think about:

  • check if the engine is started in SoloudTools.initSounds()
  • find a better way to expose SoLoud().audioEvent stream. Now it is set as a broadcast inside a singleton class. Is it worth considering moving the event stream flow to a dedicated class? Now the developer can subscribe to it (like I did wrongly) and then he needs to remove that subscription, which is not possible IIRC with a broadcast.

For now I will correct the error in the example, then maybe we should open a new issue

FWIW, I think you can cancel a broadcast stream subscription. But yeah, broadcast streams are a bit of a minefield.

I'll open a new issue that addresses the audioEvent / singleton issue more generally.

Here, apart from fixing the bug in the example, I'd like to make sure that if such a problem is encountered, we don't crash. Not from C++ land. I'd just throw a (Dart) exception instead, or something.
