flutter 切换环境

flutter 切换环境

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。
