终端运行flutter channel命令查看当前flutter 环境 分支
Mac:~ mac$ flutter channel
Flutter channels:
master
dev
beta
* stable
带有*号的为当前分支
切换分支命令 flutter channel 分支名 比如 flutter channel beta和flutter channel dev
Mac:~ mac$ flutter channel dev
Switching to flutter channel 'dev'...
git: Switched to a new branch 'dev'
git: Branch 'dev' set up to track remote branch 'dev' from 'origin'.
Successfully switched to flutter channel 'dev'.
运行flutter channel查看是否切换分支成功，如果本地没有要切换的分支命令会执行下载操作

显示如下
Flutter channels:
master
* dev
beta
stable
即是切换分支成功。
如果报错信息如下：
git: error: Your local changes to the following files would be overwritten by checkout:
git: packages/flutter/lib/src/widgets/navigator.dart
git: Please commit your changes or stash them before you switch branches.
git: Aborting
Switching channels failed with error code 1.
cd到本地flutter环境目录下执行git checkout .命令，再次执行切换分支的命令即可成功。
