flutter

Solution 1:^[1]

Brew is telling you that it can't find a formula for FVM.

Try this:

brew tap leoafarias/fvm

brew install fvm

Instructions here.

As in the official documentation of fvm:

1. Standalone (Recommended)
You can download the standalone packages from the GitHub repo here.

2. Homebrew
If you use the Homebrew package manager for Mac OS X, you can install FVM by running

- Install

brew tap leoafarias/fvm
brew install fvm

- Uninstall

brew uninstall fvm
brew untap leoafarias/fvm

3. Pub package

You are able to also install FVM as a pub package.

dart pub global activate fvm

However if you plan on using FVM to manage your global Flutter install we recommend installing as a standalone.
