Do you have a reproduce scenario? I'm not very familiar with the Flutter library nor I see any clear exception here.

@utsavDave97 could you add more information on why you have closed this issue? That could benefit other users in the future.

@dariuszseweryn Hey sorry for that. To be honest even I don't have any idea to reproduce this. But it is mainly happening for Android 12 and above. For my project I just decided to go with different library as I was not able to find a solution for this error.
