There are changes from 1 commit wherein I had to upgrade AGP version to make it work with flutter beta channel. I can remove the commit but the question is, aren't these changes required?

It's already fixed on the main branch, but your fork is a few commits behind.

One way to fix this:

git remote add upstream https://github.com/lichess-org/mobile.git
git pull upstream main --rebase
git push -f

You'll probably get a conflict with your first commit, just do git rebase --skip in that case
