MacOS + VSCode multiple flutter versions

I'm trying to have multiple flutter versions in MacOS, namely 2.0.4 & 3.7.1.

I have seen topics like this one https://stackoverflow.com/questions/71196386/vscode-quickly-switch-between-flutter-versions and followed tutorials like this one https://hackernoon.com/how-to-run-multiple-flutter-versions-on-macos-522x35ei but even after everything seems correctly defined, I'm stuck with the version 2.0.4, in the newest project.

1 - I have configured the $PATH permanently:

Old version 2.0.4

which flutter
/Users/MyUserName/Documents/flutter/bin/flutter

New version 3.7.1

which flutter371
/Users/MyUserName/Documents/flutter_3_7_1/bin/flutter371

2 - I have configured in VSCode the file /.vscode/settings.json like such:

3 - I have configured directly into VSCode settings the Flutter SDK paths like such:

Yet, when I click the in VSCode bottom navigation bar Flutter, it only shows this:

What am I doing wrong?

> Could it be that by renaming the executable to flutter371

This is the problem. When VS Code searches for a Flutter SDK in the dart.flutterSdkPaths, it looks for a bin/flutter binary to ensure it's an SDK.

One way around this be to copy the file instead of renaming it, so it's still a valid Flutter SDK. You may need to ensure these folders are in the right order in your PATH environment variable if you want to mix it with another SDK though.
