fmv
fmvfmv – flutter version management: a simple cli to manage flutter sdk versions.
why not use flutter channels?
if all you want is to use the latest stable version or a specific channel once in a while, you should be using flutter channels.
this tool allows you similar functionality to channels; however it caches those 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 tag, i.e. 1.2.0. in case you have projects in different flutter sdk versions and do not want to upgrade.
use fmv instead
easiest way npm & yarn
this is a very simple way to get started with fvm.
npm install -g fvm
# or
yarn global add fvm
# and
fvm stable
binary installation
download a compatible binary for your system. for convenience, place fvm in a directory where you can access it from the command line. usually this is /usr/local/bin.
