1.创建flutter工程目录(各项目+flutter目录),在flutter 目录下载flutter SDK

git init
git clone -b dev https://github.com/flutter/flutter.git

2.进入flutter SDK目录即flutter禁用通过 Google Analytics 发送数据

cd flutter
./bin/flutter config --no-analytics

禁用通过 Google Analytics 发送相关数据,以免国内网络连接失败问题。

3.检查flutter安装情况:flutter doctor

  • 安装XCode

    • 我机器安装的XCode版本是10.2.1,比较新了。如果安装的版本较老,可以更新下

        ksnowlvdeMacBook-Pro:flutter ksnowlv$ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
  • 打开模拟器

    • 在Mac机器上,可以通过 open -a Simulator


使用flutter create 项目名称创建项目

在使用 flutter create命令创建flutter工程时,如果报Cannot create a project within the Flutter SDK. Target directory '/Users/ksnowlv/Music/flutter/flutter/my_app' is within the Flutter SDK at '/Users/ksnowlv/Music/flutter/flutter'的错误,注意不要在flutter SDK目录及子目录下创建工程,可考虑在其它目录下创建工程。例如平级目录


使用flutter run运行app,

../flutter/bin/flutter run
