1.安装xcode
2.终端输入open ~/.bash_profile编辑内容
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export PATH=‘clone的flutter目录’/flutter/bin:$PATH
终端执行保存操作：
source ~/.bash_profile
3.创建‘clone的flutter目录’文件夹,然后在终端cd到此文件夹并执行命令：
git clone -b stable https://github.com/flutter/flutter.git
注：第一次我直接点击下载的，运行flutter doctor时报错：
Error: The Flutter directory is not a clone of the GitHub project.
The flutter tool requires Git in order to operate properly;
to set up Flutter, run the following command:
git clone -b stable https://github.com/flutter/flutter.git
如果情况一样就需要使用git clone来获取sdk
漫长的等待。。。
4.执行 flutter doctor
ziyuanxiazai:~ fonchy$ flutter doctor

║ Welcome to Flutter! - https://flutter.dev ║

║ The Flutter tool uses Google Analytics to anonymously report feature usage ║
║ statistics and basic crash reports. This data is used to help improve ║
║ Flutter tools over time. ║
║ ║
║ Flutter tool analytics are not sent on the very first run. To disable ║
║ reporting, type 'flutter config --no-analytics'. To display the current ║
║ setting, type 'flutter config'. If you opt out of analytics, an opt-out ║
║ event will be sent, and then no further information will be sent by the ║
║ Flutter tool. ║

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.12.13+hotfix.9, on Mac OS X 10.15.3 19D76,
locale zh-Hans-US)
[✗] Android toolchain - develop for Android devices
✗ Unable to locate Android SDK.
Install Android Studio from:
https://developer.android.com/studio/index.html
On first launch it will assist you in installing the Android SDK
components.
(or visit https://flutter.dev/setup/#android-setup for detailed
instructions).
If the Android SDK has been installed to a custom location, set
ANDROID_HOME to that location.
You may also want to add it to your PATH environment variable.
[!] Xcode - develop for iOS and macOS (Xcode 11.3.1)
! CocoaPods 1.5.3 out of date (1.6.0 is recommended).
CocoaPods is used to retrieve the iOS and macOS platform side's plugin
code that responds to your plugin usage on the Dart side.
Without CocoaPods, plugins will not work on iOS or macOS.
For more info, see https://flutter.dev/platform-plugins
To upgrade:
sudo gem install cocoapods
[!] Android Studio (not installed)
[✓] VS Code (version 1.43.2)
[✓] Connected device (3 available)
! Doctor found issues in 3 categories.
发现其中有“Android toolchain - develop for Android devices”前面有个红色 [x],其实只要保证Xcode 和 Android toolchain 有一个成功就行，当然也可以再下载补全
注：flutter doctor -v 查看配置并有提示安装的命令，直接复制粘贴运行即可
