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

Features:

• 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 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. v1.2.0 or 1.17.0-dev.3.1. In case you have projects in different Flutter SDK versions and do not want to upgrade.

Usage

To Install:

> pub global activate fvm

Read dart.dev docs for more info on how to run global dart scripts.

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 v1.8.0 or 1.17.0-dev.3.1 to install the release.

Project Config SDK Version

If your project is already configured to use an specifc version. Run install without any arguments will make sure the proper version is installed for the project.

> fvm install

Check out use command to see how to configure a version per project.

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>

If you want to use a specific version by default in your machine, you can specify the flag --global to the use command. A symbolic link to the Flutter version will be created in the fvm home folder, which you could then add to your PATH environment variable as follows: FVM_HOME/default/bin. Use fvm use --help, thsi will give you the exact path you need to configure.

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. This command will also output where FVM stores the SDK versions.

> fvm list

Change FVM Cache Directory

There are some configurations that allows for added flexibility on FVM. If no cache-path is set, the default fvm path will be used.

fvm config --cache-path <path-to-use>

List Config Options

Returns list of all stored options in the config file.

fvm config --ls

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

Call Local SDK Directly

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

> .fvm/flutter/bin 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.

Configure Your IDE

In some situations you might have to restart your IDE and the Flutter debugger to make sure it uses the new version.

VSCode

Add the following to your settings.json. This will list list all Flutter SDKs installed when using VSCode when using Flutter: Change SDK.

Use fvm list to show you the path to the versions.

List all versions installd by FVM

{
  "dart.flutterSdkPaths": ["/Users/usr/fvm/versions"]
}

You can also add the version symlink for dynamic switch

{
  "dart.flutterSdkPaths": [".fvm/flutter_sdk"]
}

Android Studio

Copy the absolute path of fvm symbolic link in your root project directory. Example: /absolute/path-to-your-project/.fvm/flutter_sdk

In the Android Studio menu open Languages & Frameworks -> Flutter or search for Flutter and change Flutter SDK path. Apply the changes. You now can Run and Debug with the selected versions of Flutter.
