Flutter Version Management: A simple cli to manage Flutter SDK versions.


  • Configure Flutter SDK version per project
  • Ability to install and cache multiple Flutter SDK Versions
  • Easily switch between Flutter channels & versions
  • Per project Flutter SDK upgrade

Version Management #

This tool allows you to manage multiple; however, it caches these versions locally, so you don't have to wait for a full setup every time you want to switch versions.

Also, it allows you to grab versions by a specific release, i.e. 1.2.0. In case you have projects in different Flutter SDK versions and do not want to upgrade.

Usage #

To Install:

> pub global activate fvm

And then, for information on each command:

> fvm help

Install a SDK Version #

FVM gives you the ability to install many Flutter releases or channels.

> fvm install <version>

Version - use master to install the Master channel and 1.8.0 to install the release.

Use a SDK Version #

You can use different Flutter SDK versions per project. To do that you have to go into the root of the project and:

> fvm use <version>

Remove a SDK Version #

Using the remove command will uninstall the SDK version locally. This will impact any projects that depend on that version of the SDK.

> fvm remove <version>

List Installed Versions #

List all the versions that are installed on your machine.

> fvm list

Running Flutter SDK #

There are a couple of ways you can interact with the SDK setup in your project.

Proxy Commands #

Flutter command within fvm proxies all calls to the CLI just changing the SDK to be the local one.

> fvm flutter run

This will run flutter run command using the local project SDK.

Call Local SDK Directly #

FVM creates a symbolic link within your project called fvm which links to the installed version of the SDK.

> ./fvm run

This will run flutter run command using the local project SDK.

As an example calling fvm flutter run is the equivalent of calling flutter run using the local project SDK.
