2021-01-11 使用fvm 管理多版本flutter
- fvm安装
- fvm配置flutter多版本
- fvm切换flutter
- 配置flutter业务工程dart 和flutter sdk path
1、fvm安装
fvm git官网
方法1
https://github.com/befovy/fvm
brew tap befovy/taps
brew install fvm
方法2
https://pub.flutter-io.cn/packages/fvm
pub global activate fvm
2、fvm使用
fvm help

修改FVM_HOME环境变量，配置fvm 目录为/opt/fvm

fvm install失败问题！！
fvm install beta -v
fvm: Command 'git' exited with error: chdir /opt/fvm/versions/beta: no such file or directory
/opt/flutter/之前安装的flutter（(也就是通过git clone的flutter)） 拷贝到/opt/fvm/versions 目录下面
再次执行
fvm install beta -v
成功了！
fvm: Running git --version to check if git is available
fvm: beta is a valid flutter channel
fvm: Flutter channel beta is already installed
同样的方法， 拷贝多次flutter，
然后手动切换到对应版本（cd到flutter git仓库下，git checkout 1.17.3 想切换到那个分支或者tag就切换到哪个），
再对拷贝到fvm/versions/下面文件夹重新命名,
比如切换到1.17.3的tag下面， 改名为1.17.3
ls -l /opt/fvm/versions
total 0
drwxr-xr-x@ 29 huchu wheel 928 Jan 8 02:19 1.17.3
drwxr-xr-x@ 28 huchu wheel 896 Jan 8 00:49 beta
ll /opt/fvm
total 0
-rw-r--r-- 1 huchu wheel 0 Jan 8 01:10 config.yaml
lrwxr-xr-x 1 huchu wheel 24 Jan 11 10:52 current -> /opt/fvm/versions/1.17.3
drwxr-xr-x 5 huchu wheel 160 Jan 11 12:01 versions
但是这样copy flutter，dart的cache 比较大
所以直接到官方重新下载好对应的版本
https://flutter.cn/docs/development/tools/sdk/releases?tab=macos
flutter_macos_1.17.3-stable.zip
flutter_macos_1.22.5-stable.zip
flutter_macos_1.25.0-8.3.pre-beta.zip
然后拷贝到/opt/frm/versions下
分别到fvm use 个版本，到flutter工程下pub get得到了最适合大的大小
du -sh *
2.1G 1.17.3
1.9G 1.22.5
1.3G beta
3、fvm切换flutter版本
current实际上是一个软连接，
随着fvm use 修改，其实就是改这个软连接
1、切换flutter到 beta
fvm use beta
fvm: .DS_Store exists but was not setup correctly. Doing cleanup...
fvm: Add /opt/fvm/current/bin to path to make sure you can use flutter from terminal
export PATH="/opt/fvm/current/bin:$PATH"
fvm: beta is active
flutter doctor

2、切换flutter到1.17.3
fvm use 1.17.3
fvm: Add /opt/fvm/current/bin to path to make sure you can use flutter from terminal
export PATH="/opt/fvm/current/bin:$PATH"
fvm: 1.17.3 is active
flutter doctor

4、配置flutter业务工程
打开android studio
Languages & Frameworks
Dart
Dart SDK Path 修改为/opt/fvm/current/bin/cache/dart-sdk
Flutter
Flutter SDK Path修改为/opt/fvm/current
flutter doctor
Waiting for another flutter command to release the startup lock...
^C
rm /opt/fvm/current/bin/cache/lockfile
flutter doctor
