macOS上搭建Flutter开发环境

前言

看到Flutter，今天搭建记录一下。

使用镜像

由于在国内访问Flutter有时可能会受到限制，Flutter官方为中国开发者搭建了临时镜像，大家可以将如下环境变量加入到用户环境变量中：

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

注意： 此镜像为临时镜像，并不能保证一直可用，读者可以参考详情请参考 Using Flutter in China 以获得有关镜像服务器的最新动态。

下载Flutter SDK

# wget https://storage.googleapis.com/flutter_infra/releases/stable/macos/flutter_macos_1.17.3-stable.zip

# unzip flutter_macos_1.17.3-stable.zip

设置环境变量

export PATH=/work/tools/flutter/flutter/bin:$PATH

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

下载Android Studio

https://developer.android.com/studio 进行下载，下载后会要求下载Android SDK，按照提示下载即可。

Flutter 检查
