I tried all previous solution but nothing worked for me.
Please help to solve this issue is not same I searched
Thanks in advance.

[TahaTesser]

Hi @skroys
Please run build -> clean and try again
can you please provide your flutter doctor -v and flutter run --verbose?
Also, to better address the issue, would be helpful if you could post a minimal code sample to reproduce the problem
Thank you

[sunilcoder36]

Thanks for response @TahaTesser . But I already tried solution on stackoverflow but not working.
Sample code to reproduce this issue I already provided all files above in issue.
