Flutter Sound Version :

• FULL or LITE flavor ? Tried with both latest version

• Important: Result of the command : flutter pub deps | grep flutter_sound

Severity

• Crash? Yeah

• Result is not what expected? Exactly it crashes

• Cannot build my App? The app can be built but crashes

Turns out by checking this other issue: https://github.com/Canardoux/flutter_sound/issues/689 I realized I could check the default SampleRate and it works with 16000hz.

We could definitely have a better error message for when this crashes. Also we could support 44100Hz as a sample rate on ipad 🤔

Hope this can actually save some search time for someone else.
