Fixing "Downloaded executables cannot execute on the host" in Flutter Doctor

Hey there, let's work through this frustrating flutter doctor error you're hitting. I know you checked that GitHub issue and only found Linux-specific fixes, so here are some platform-agnostic and targeted steps to get things working:

Fix file execution permissions
This is the most common culprit. The downloaded Flutter tools might not have the right permissions to run on your system. Open your terminal and run this command (replace <your-flutter-sdk-path> with the actual path to where you installed Flutter):
```
chmod -R +x <your-flutter-sdk-path>/bin/cache
```
This recursively adds execute permissions to all files in the Flutter cache directory, which should let the tools run properly.
Clear and rebuild the Flutter cache
Corrupted cache files can also cause this error. Start by cleaning your project's build files:
```
flutter clean
```
Then run flutter doctor again—this will trigger a re-download of any missing or corrupted executable files. If you're working with Android, you can also run flutter doctor --android-licenses to make sure all required licenses are accepted, which sometimes resolves related execution issues.
Verify your system architecture matches your Flutter SDK
If you're on an ARM-based system (like M1/M2 Macs) or a 32-bit machine, make sure you downloaded the Flutter SDK built for your architecture. For example, x86 SDKs won't run properly on ARM Macs. Grab the correct version from the Flutter official site, replace your existing SDK, and try flutter doctor again.
Double-check your environment variables
Ensure your PATH includes the Flutter bin directory, and that FLUTTER_HOME (if you set it) points to the correct SDK location. A misconfigured path can prevent the system from finding and executing the Flutter tools correctly.
Reinstall the Flutter SDK
If none of the above works, a fresh install might be the way to go. Back up your projects, delete your current Flutter SDK directory, download the latest stable version, set up your environment variables again, and run flutter doctor once more.
