fvm
命令：pub global activate fvm
$ pub global activate fvm
Package fvm is currently active at version 2.0.5.
Resolving dependencies... (3.4s)
The package fvm is already activated at newest available version.
To recompile executables, first run `global decativate fvm`.
Installed executable fvm.
Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path.
You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):
export PATH="$PATH":"$HOME/.pub-cache/bin"
Activated fvm 2.0.5.
- 配置
.bash_profile中添加：
# fvm
export PATH="$PATH":"$HOME/.pub-cache/bin"
使.bash_profile生效：
source ~/.bash_profile

fvm緩存路徑（可選撵儿，默認在用戶目錄下fvm/versions文件夾）：
fvm config --cache-path <CACHE_PATH>
- 查看當前安裝的flutter版本：
$ fvm list
No SDKs have been installed yet. Flutter. SDKs installed outside of fvm
will not be displayed.
- 安裝指定版本的flutter：
$ fvm install 2.2.1
Flutter "2.2.1" is not installed.
Installing version: 2.2.1...
Cloning into '/Users/yuanzhiying/fvm/versions/2.2.1'...
- 刪除指定版本：
$ fvm remove 2.2.0
Removing 2.2.0...
2.2.0 removed.
此時會在用戶目錄下自動創(chuàng)建fvm/versions/2.2.1文件夾弯菊，如果本地已有flutter巷疼，可將本地的flutter拷貝到versions目錄下咕娄，文件夾改為對應(yīng)的版本名灾杰。當前flutter版本可以在flutter根目錄下的version文件里查看荣茫。

- 便捷使用命令
在.bash_profile中設(shè)置命令的別名：
# aliases 快捷使用fvm命令
alias flutter="fvm flutter"
alias dart="fvm dart"
使生效：
source ~/.bash_profile
