difficulty in playing multiple sounds

[harshrocks]

The UI is working fine but an error comes whenever I press the button.

E/flutter (15820): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: Unable to load asset: assets/1.wav

Here's the code

Actually I copied and pasted the code from one of the projects to see whether some problem is there in my code.

Here's the pubspec

Please help, I am stuck here and I don't want to go on further before busting this error.
Please help!!!

Hiya did you find the solution yet? there is typo in your code, instead using the $soundNumber.wav you should change the extension in your assets folder to *.wav not the *.WAV, you should change either in your dart files or your audio filename
