How it works

This script creates/maintains a symlink to the Flutter SDK of choice. It provides a way to quickly switch Flutter SDK version globally for the whole system.

How to use it

1. Put flutter_version.sh into your home folder
2. Run chmod +x flutter_version.sh
3. Replace ~/Documents/SDKs on line 16 with a path to the folder where you want to store the Flutter SDK versions
4. Download and put whichever versions of flutter you'd like to switch between into <SDKs path>/flutter_versions folder and name them conveniently. Something like 1.12 and 1.16_beta will work well.
5. Add /flutter/bin into PATH
