The Bop music player is crashing when I remove a song and click on track changer next/previous button.

Project Information

• Repository: https://github.com/iamSahdeep/Bop
• Project Name: Bop music player

Expected behavior

I expected that after removing the song it will stop to play or the player will move to another song. I think this not weird than freezing the app by taping on the next/previous button. I expected the app will run smoothly after I clicked on that button.

Actual behavior

The crash happens after I removed a playing/running song from all songs folder and clicked on the previous/next button.

How to reproduce

Steps to reproduce the behavior:

1. Launch the app and go to "All Songs" folder.
2. Click on a song (The song will start to play)
3. Tap on ⋮ (Three dots/ Vertical ellipsis) and remove that song (You will notice the song is started to play again from the beginning).
4. Then tap on music logo.
5. Then click on next or previous button.
6. Finally, See error.

• App version: Bop music player v1.2
