I am new at flutter. I am currently using FlutterFlow to develop and for custom coding I am using Flutter on VS code.
I think I am doing something wrong while installing flutter (check flutter doctor) that's why I am getting this error.
Please let me know what is going wrong.
FYI - App runs on emulator and I am able to do USB debug but not able to make APK.

Terminal -

parthsheth@Parths-MacBook-Air fineappl-pat % flutter build apk                

 Building with sound null safety

This here is the most relevant error message

[!] Flutter (Channel master, 3.5.0-12.0.pre.130, on macOS 13.0 22A380
    darwin-arm64, locale en-IN)
    ✗ Downloaded executables cannot execute on host.
      See https://github.com/flutter/flutter/issues/6207 for more information

It tells you that the flutter installation itself has not been correctly installed. And sadly, the linked GitHub issue is not very helpful as it refers to Linux systems mostly. Potential fixes for macOS are being discussed here and here. Right now you have a flutter installation which is incompatible with your system (Apple Silicon and macOS Ventura).

The solution seems to be to upgrade your flutter version

  1. flutter upgrade
  2. Remove the cache files at <flutter_installation_path>/flutter/bin/cache

After doing that, check your installation once again via flutter doctor

    Used 'rm -rf ~/Developer/flutter/bin/cache' This helped me to remove all error from flutter doctor. Thank you @jraufeisen – ErasableNinja Nov 13 '22 at 16:23

Solved

Steps are as follow -

flutter upgrade

Upgrades flutter to latest version

rm -rf ~/Developer/flutter/bin/cache (/path/dir)

This will remove all the old cached files.

flutter doctor

This will reinstall all the cached files as per new SDK(flutter upgrade).

flutter doctor

But even after this if you try to run flutter build apk it won't work.

sudo softwareupdate --install-rosetta --agree-to-license

Accept this license and you're good to go. Turns out this was the main issue.

Thanks @jraufeisen for your help.
