This problem was resolved by upgrading Flutter --version from 2.5.3 to 2.8.1.
Source URL: https://minpro.net/your-flutter-checkout-has-local-changes-that-would-be-erased-by-upgrading
FIXED, for my case is file permission problem, with flutter admin helped.
https://github.com/flutter/flutter/issues/94692
but the root cause i think that is the error prompt is not obvious,
you may take a look at the investigation steps to see why,
and you may find yours solutions
Try to update pods, go to your ios folder, run
pod deintegrate
, and thenrun ‘
pod install
‘. if this does not help then runpod update
or ‘pod repo update
‘. try to find which package is giving issues, and changes their versions.
