Keeping informed

No matter which one of the Flutter release channels
you follow, you can use the flutter command to upgrade your
Flutter SDK or the packages that your app depends on.

Upgrading the Flutter SDK

To update the Flutter SDK use the flutter upgrade command:

flutter upgrade

This command gets the most recent version of the Flutter SDK
that’s available on your current Flutter channel.

If you want an even more recent version of the Flutter SDK,
switch to a less stable Flutter channel
and then run flutter upgrade.

Switching Flutter channels

Flutter has three release channels:
stable, beta and master.
