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


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

Version Management

This tool allows you to manage multiple channels and releases, and 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.


To Install fvm:

brew tap befovy/taps
brew install fvm

Or install fvm through

go get
> go get -u -v

The command above will install binary executable fvm file to

to your system PATH, or move the binary fvm file to an existing PATH directory.

And then, for information on each command:

> fvm help


fvm use environment variable

as a working path.
The installed cache and config file are all stored in this path.

If no

in environment variable, fvm will use the default value returned by
On Mac OS, default
$HOME/Library/Application Support/fvm

Install a SDK Version

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

> fvm install 


to install the Master channel and
to install the release.


to install flutter from unoffical repo ```bash

fvm install master --repo ```

Import Flutter from previous installation

FVM has subcommand

which can import your previous installed flutter into fvm.
> fvm import 

If you have installed master channel flutter, just use

fvm import master
Or if you have installed a special derived flutter, just use any name you want to import this flutter. You can use a name from you company, or any other you want.
fvm import xianyu

Use a SDK Version

You can use the installed Flutter SDK versions for your computer user account globally. To do that just:

> fvm use 

Also, 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  --locol

Show current SDK info

Get current active Flutter sdk version, link path and actually path

> fvm current

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 

List Installed Versions

List all the versions that are installed on your machine.

> fvm list

Running Flutter SDK

Call Global SDK

After add fvm global path to your system environment variable,

command is usable every where.

Your will get tip when you run

fvm use 

Proxy Commands

Flutter command within

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. If no FVM config is found in the project. FMV will recursively try for a version in a parent directory.

If FVM config is still not found, this will run

flutter run
command using the global Flutter SDK.

Call Local SDK Directly

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


to your PATH, or ```bash

.fvm/current/bin/flutter 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.
