我的项目使用不向后兼容的包，
我厌倦了在新 PC 上安装，但它安装了最新的 Flutter 并且我无法降级 Flutter

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

我也试过 stable 和 beta

$ 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".

我也试过:

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

Answer 1

cd 到 flutter 目录，例如/home/elia/snap/flutter/common/flutter然后做:git checkout 1.22.6
