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
重启命令行工具，执行fvm：
$ fvm
Flutter Version Management: A cli to manage Flutter SDK versions.
Usage: fvm <command> [arguments]
Global options:
-h, --help Print this usage information.
--verbose Print verbose output.
--version current version
Available commands:
config Set configuration for FVM
dart Proxies Dart Commands
doctor Shows information about environment, and project configuration.
flavor Switches between different project flavors
flutter Proxies Flutter Commands
global Sets Flutter SDK Version as a global
install Installs Flutter SDK Version
list Lists installed Flutter SDK Versions
releases View all Flutter SDK releases available for install.
remove Removes Flutter SDK Version
spawn Spawns a command on a Flutter version
use Sets Flutter SDK Version you would like to use in a project
Run "fvm help <command>" for more information about a command.

fvm相关命令
- 配置
fvm缓存路径（可选，默认在用户目录下fvm/versions文件夹）：
fvm config --cache-path <CACHE_PATH>
- 查看当前安装的flutter版本：
$ fvm list
No SDKs have been installed yet. Flutter. SDKs installed outside of fvm
will not be displayed.
- 安装指定版本的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'...
- 删除指定版本：
$ fvm remove 2.2.0
Removing 2.2.0...
2.2.0 removed.
此时会在用户目录下自动创建fvm/versions/2.2.1文件夹，如果本地已有flutter，可将本地的flutter拷贝到versions目录下，文件夹改为对应的版本名。当前flutter版本可以在flutter根目录下的version文件里查看。
/Users/yuanzhiying/fvm/versions/1.22.6
- 查看已安装的flutter版本：
$ fvm list
Cache Directory: /Users/yuanzhiying/fvm/versions

flutter命令的使用
此时执行flutter doctor找不到flutter命令：
$ flutter doctor
zsh: command not found: flutter
所有flutter命令前加上fvm即可：
$ fvm flutter doctor

$ fvm flutter pub get

flutter下dart命令的使用
所有dart命令前加上fvm即可：
$ fvm dart --version
fvm: running Dart from Flutter "1.22.6"
Dart SDK version: 2.10.5 (stable) (Tue Jan 19 13:05:37 2021 +0100) on "macos_x64"
- 便捷使用命令
在.bash_profile中设置命令的别名：
# aliases 快捷使用fvm命令
alias flutter="fvm flutter"
alias dart="fvm dart"
使生效：
source ~/.bash_profile
重启命令行工具。
$ flutter pub get
Running "flutter pub get" in info_valley... 1.0s
$ dart --version
Running using Flutter version configured in path.
Dart SDK version: 2.13.1 (stable) (Fri May 21 12:45:36 2021 +0200) on "macos_x64"
- 设置全局默认的flutter版本
$ fvm global 1.22.6
Flutter "1.22.6" has been set as global
However your "flutter" path current points to:
.
to use global Flutter SDK through FVM you should change it to:
/Users/yuanzhiying/fvm/default/bin
此时fvm目录下自动生成了一个default的快捷文件夹。
