DSwitch is a cli tool that allows you to rapidly switch between channels and versions of Dart.

If you are a flutter user then you are better off using FVM as FVM changes the version of Dart embedded in Flutter.

DSwitch is intended to help manage a standalone version of Dart if you are doing things like building CLI applications.

For those interested, DSwitch is written in Dart using the DCli api library.

DSwitch can switch between Dart Channels (stable, beta, dev) as well as versions within those channels.

Upgrading to 8.0.0

DSwitch 8.0.0 requires Dart 3.13 or later. SDKs downloaded by older DSwitch versions remain on disk, but DSwitch 8.0.0 only treats a version as cached after it has completed the new verified installation process. Reinstall a version with dswitch <channel> install <version> before switching to it. You can remove an old cached directory with dswitch <channel> delete <version>.

Switching between Dart channels is as easy as:

dswitch use beta

Unit tests

Use the critical_test package to run unit tests as we use a ct pre_hook to activate dswitch from source to run the tests.
