Mac 配置flutter

1.下载flutter的SDK，解压后放置随便路径

https://flutter.dev/docs/development/tools/sdk/releases?tab=macos

2.修改配置环境变量（路径为sdk解压后的放置路径）

vim ~/.bash_profile

//添加以下配置（/Users/mac/flutter是我的sdk解压路径）

export PATH=/Users/mac/flutter/bin:$PATH

export PUB_HOSTED_URL=https://pub.flutter-io.cn

export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

:wq保存后 执行下 source ~/.bash_profile

3.检测环境

flutter -h 出现flutter帮助信息说明sdk安装配置成功

4.运行条件检测

flutter doctor 检测运行条件

一般需要依次运行以下命令：

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

brew update

brew install --HEAD usbmuxd

brew link usbmuxd

brew install --HEAD libimobiledevice

brew install ideviceinstaller

brew install ios-deploy

//如果brew update运行慢—————————————————————————

# 替换brew.git:

$ cd "$(brew --repo)"

# 中国科大:

$ git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

# 清华大学:

$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

# 替换homebrew-core.git:

$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

# 中国科大:

$ git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

# 清华大学:

$ git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

# 替换homebrew-bottles:

# 中国科大:

$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile

$ source ~/.bash_profile

# 清华大学:

$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile

$ source ~/.bash_profile

# 应用生效:

$ brew update

完成后flutter doctor应该是这样的

Doctor summary (to see all details, run flutter doctor -v):

5 . 创建第一个flutter项目

cd 到项目文件夹后 使用flutter create xxxx_xxxx_xxx 即可 # 注意：项目名不能有大写字母！！！！！

6. 修改文件夹权限

sudo chmod -R 777 flutter_demo_01 //项目文件夹

sudo chmod -R 777 /Users/mac/flutter //sdk文件夹

7 .xcode 直接打开ios目录下的工程文件即可

8 .vscode 打开工程目录，运行flutter run即可。
