安装软件

参考

• Windows install
• macOS install
• Using Flutter in China

git

git 代码版本控制

https://git-scm.com/

Android Studio

安装

官网

https://developer.android.com/studio/index.html?hl=zh-cn

选择需要的版本下载，intel apple cpu 区分下

首次安装需要去下载 sdk，一路默认就行，请打开加速，这个 dl.google.com 不太稳

SDK 配置

点击 “SDK Manager”

SDK 列表, 可以先勾选个 Android 12 的，以后根据需要再加

SDK Tools, 安装 command-line、x86 加速器

XCode

安装

Apple Store 中升级到最新的 xcode

如果你原来的 xcode 很大，可以直接删除，装个新的

cocoapods

https://cocoapods.org

$ sudo gem install cocoapods

M1 机器

$ sudo gem uninstall ffi && sudo gem install ffi -- --enable-libffi-alloc

配置 command-line

多个版本需要配置你的 xcode 主目录，默认不需要操作

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

同意 Xcode license

同意协议，默认不需要操作

$ sudo xcodebuild -license

Flutter SDK

压缩包方式

sdk 压缩包列表

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

我现在用的 2.10.5 , v3 大家还是再等等

比如你解压到 ~/Documents/sdk/flutter

环境变量

• macos

打开 .bash_profile 配置文件

$ vi ~/.bash_profile

写入配置

# flutter sdk
export PATH=${PATH}:~/Documents/sdk/flutter/bin

# dart sdk
export PATH=${PATH}:~/Documents/sdk/flutter/bin/cache/dart-sdk/bin
export PATH=${PATH}:~/.pub-cache/bin

# flutter-io 国内镜像
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

# android
export ANDROID_HOME=~/Library/Android/sdk
export PATH=${PATH}:${ANDROID_HOME}/platform-tools
export PATH=${PATH}:${ANDROID_HOME}/tools

生效

$ source ~/.bash_profile

检查

$ flutter doctor

输出

$ flutter doctor
