You can just go from a version to another using the new commands

flutter downgrade -> go to the previous
flutter upgrade -> update to the new one

If you have a specific version of Flutter that you want to switch to (e.g. a previous stable version), you can use the flutter version command:

First find the version you wish to switch to here: https://flutter.dev/docs/development/tools/sdk/releases

Then, use flutter version command:

 flutter version v1.9.1+hotfix.3

To pin Flutter package to a specific version, specify Flutter version explicitly in the pubspec.yaml file environment section:

environment:
  sdk: '>=1.19.0 <3.0.0'
  flutter: ^0.1.2

The new command is: ``` Warning: "flutter version" will leave the SDK in a detached HEAD state. If you are using the command to return to a previously installed SDK version consider using the "flutter downgrade" command instead. ```

You have to run one command

flutter version

Above command shows you list of flutter version after that you can choose any version from that list. Using for example flutter version v1.9.1+hotfix.6

Based on this,

In the Flutter install directory execute

git fetch

then

git checkout <version number>

Eg: git checkout 3.13.7, notice there is no 'v' prefix in front of version number instead just write the version directly

Now run

flutter doctor
