There is no previously recorded version for channel "dev".

I tried on stable and beta as well

$ flutter downgrade v1.22.6
There is no previously recorded version for channel "stable".

flutter downgrade 1.22.6
There is no previously recorded version for channel "beta".

I also tried:

$ flutter version v1.22.6
WARNING: Flutter version command has been removed, using latest from channel

Answer 1

cd to flutter directory, e.g. /home/elia/snap/flutter/common/flutter

then do:

git checkout 1.22.6

Answer 2

1. open flutter SDK directory on terminal, and type git checkout <sdk-version> e.g git checkout 2.5.0. just make sure the version you are asking for, is correct as in the sdk documentation (https://docs.flutter.dev/development/tools/sdk/releases).
2. Type flutter --version. if terminal dispaying something like Downloading Dart SDK from Flutter engine . . . means you just have to wait for the download update to finish.
3. when download has finish, type again flutter --version to make sure that the sdk has changed.
4. finish.

Answer 3

You can download the version you want from the Flutter SDK release page then install it as your Flutter SDK on your machine.

Answer 4

Download the version you want from the Flutter sdk release page and select that SDK path in Settings> Language and Framework > Flutter .

If it throws the error " the flutter sdk is incomplete.." Simply navigate to where you downloaded the SDK then Flutter> Bin> Flutter.bat

This will download the remaining files for the sdk. You can then select the sdk path without error

SDK Release page

Answer 5

Go to your flutter install folder. If you do not know installation path, use this command:

flutter sdk-path

Then use git to downgrade

git checkout <VERSION>
flutter --version

This will download the specified version and downgrade flutter.
