Sometimes we need to have multiple Flutter versions on the same machine for different projects. To do this, we should download multiple versions and add those paths to the bash_profile file and our IDE. I will use macOS and Visual Studio Code.

I assume that Flutter is already installed. So we should already have a Flutter SDK folder. Let's download a different version of Flutter and place it in the same folder as the current SDK folder.

In my case, as a default, I had an older version of Flutter. In addition to that, I downloaded the stable channel and renamed it

flutter_stable
. Now I have two versions in two different paths:

Next, we duplicate the

flutter_stable/bin/
flutter
file and rename it to
flutter_stable/bin/
flutterstable
. Actually, we can give it any name. We will use this name instead of the
flutter
command, like
flutterstable --version
.

Now execute

nano ~/.bash_profile
or
nano ~/.zshrc
depending on the shell and add the path of the new version. In my case, it looks like this (I added the second row):

export PATH="$PATH:/Users/user/flutter/bin"
export PATH="$PATH:/Users/user/flutter_stable/bin"

Save, exit, and restart the terminal.

Verify if the path is correct with the command

which flutterstable
. It must give something like this:
/Users/user/flutter_stable/bin/flutterstable
.

Now the

flutterstable --version
and
flutter --version
commands should give different versions.

Visual Studio Code

Every project can use a specific version of Flutter. Open the settings of Visual Studio Code (

Cmd+,
) and search 'flutter sdk paths'. Select the 'Dart & Flutter' in the left menu, click 'Add item', and add the paths. In my case the result looks like this:

Restart Visual Studio Code.

Now, you can select the Flutter version using

cmd+shift+p
--> "
Flutter: Change SDK
". After selecting the Flutter SDK, the value of "
dart.flutterSdkPath
" in
.vscode/settings.json
should be changed to the path of the selected Flutter SDK.

As a result, we have two different versions of Flutter and we can use different versions for different projects.
