  1. Chosen as BEST ANSWER

    This problem was resolved by upgrading Flutter --version from 2.5.3 to 2.8.1.

  2. 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

  3. Try to update pods, go to your ios folder, run pod deintegrate, and then
    run ‘pod install‘. if this does not help then run pod update or ‘pod repo update‘. try to find which package is giving issues, and changes their versions.
