在mac上安装flutter

下载安装

访问flutter 中文网

我选择的是 stable 2.8.1

SDK 的下载地址是 Downloads,mac 会自动解压文件

将 flutter 添加到 path

在使用 flutter 命令前，需要更新 path
vim ~/.zshrc
下面是 android studio / flutter / java 的配置，看下自己缺什么就补上

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=${PATH}:/Users/wuyangjiacuo/Downloads/flutter/bin:$PATH

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home/

然后ESC + :wq保存并退出
最后source ~/.zshrc刷新下 path

flutter doctor

flutter doctor 是 flutter sdk 提供的一个检测环境的工具
在我们设置好 path 后，comman line 里面输入flutter doctor就可以检测 flutter 运行所需的各种工具
我的输出结果是

Running "flutter pub get" in flutter_tools...                      18.3s

可以看到我还没有安装 android 所需的工作链，xcode 的版本也偏低
因为我是安卓手机，所以就折腾安卓相关的就可以了。

abdroid 配置

android studio 下载地址
可以直接参考官方文档

已经安装了 android studio 的可以在 performance 里面的 system setting 里面查看 sdk 和 command line 是否正确安装，都正确安装后再次运行
flutter doctor就可以看到都是 ok 的了，没有 ok 的根据提示执行对应的操作就行
