Fvm is not recognized as an internal or external command, operable program or batch file.

DISCOVER FLUTTER — WEEK #9

Flutter Version Manager (or FVM) is the easiest way to manage Flutter SDK versions on your machine. So I could say it is a local development game-changer like NVM is.

This means that we can define a specific Flutter version for each project. Additionally, they get cached, so we don’t have to go through the full installation process all the time.

The following is an explanation of the installation and setup process of the FVM on a Linux operating system.

1. Install FVM on Your Machine

• First, make sure that Flutter is installed. In the command line, execute the flutter command:

• Once we have determined that Flutter is installed, we can execute the pub global activate fvm command:

• There is a warning message at the end of the installation process. So the next step would be to add fvm path to our shell’s config file (.bashrc, bash_profile, etc.). In order for the fvm command to work, it is necessary that you have three following lines defined within the file:

• Executeecho $PATH to confirm that you have successfully added a path to the FVM.
• If that is the case, you can execute the fvm command and see all available options that this CLI offers:

2. Install Flutter SDK Version With FVM

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

• To install the stable Flutter SDK version, execute fvm install stable.The installation process may take a while.

• If you want to check out all the Flutter releases that you can download, just execute fvm releases:

• To install a concrete version (e.g. 1.22.0), just execute fvm install <version you want>:

• To list all installed SDK versions, executefvm list:

3. Use FVM in Your Project

The goal is to apply a specific Flutter version to your project by using FVM.

• Create a Flutter project in your development folder by executing flutter create project_name:

• Switch to your project directory and executefvm use [version.you.want]:

• If you run fvm listonce again, you can see a tick mark by the version you are using in the project:

4. Set Up Your IDE to Understand Which SDK Version You Are Using

The last step is to configure your IDE. In my example, I will show you how to finish the setup process inAndroid Studio.

• Open the created project in Android Studio.
• Open a terminal in the IDE and navigate totheflutter_sdk folder to get the full path of the SDK by using the pwd command. Copy that path:

• Open Settings and search for Flutter. The next window will appear. Paste the path to the framed section marked in the photo below:

• Click Apply and restart the IDE. Voila, you are finished!

If you are wondering how you can configure the VSC IDE, see the official docs.
