一：Flutter环境配置
1：Flutter SDK下载
这里我下载的是flutter_macos_v1.7.8+hotfix.4-stable解压到盘目录/Users/yaodong/flutter
2：环境配置
首先查看自己所使用的shell https://support.apple.com/zh-cn/HT208050
如果是 bash
环境变量配置：
vim ~/.bash_profile
添加环境变量：
export PATH="/Users/yaodong/flutter/bin:$PATH"
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_UUL=https://storage.flutter-io.cn
保存后刷新：
source ~/.bash_profile
如果是 zsh
环境变量配置：
vim .zshrc
添加环境变量：
export PATH="/Users/yaodong/flutter/bin:$PATH"
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_UUL=https://storage.flutter-io.cn
保存后刷新：
source .zshrc
注意：终端编辑命令i编辑，esc输入命令，:wq保存并退出
3：运行 flutter doctor
打开 终端，输入flutter doctor
- 出现：Android证书问题
//出现 Android证书问题
! Some Android licenses not accepted. To resolve this, run: flutter doctor -- android-licenses
//执行
flutter doctor --android-licenses 一直Yes即可
- 出现：Xcode 环境设备验证问题
// 出现Xcode 环境设备验证
// mac os 10.15版本 软件安装目录有问题，务必更新到brew最新版本2.1.9
Verify that all connected devices have been paired with this computer in Xcode.
// 按提示依次执行
To update with Brew, run:
brew update
brew uninstall --ignore-dependencies libimobiledevice
brew uninstall --ignore-dependencies usbmuxd
brew install --HEAD usbmuxd
brew unlink usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
brew install ideviceinstaller
- 出现 ios-deploy 未安装
//这个是终端安装和调试iPhone应用的是第三方开源库
[!] iOS tools - develop for iOS devices
✗ ios-deploy out of date (1.9.4 is required). To upgrade with Brew:
brew upgrade ios-deploy
// 我这里使用node安装的
- 出现：开发环境配置问题（下面会讲到）
// 出现 开发环境配置问题，下面会讲到
[!]Android Studio (version 3.4)
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
//如果安装了 IntelliJ IDEA 也会检测到
[!] IntelliJ IDEA Ultimate Edition (version 2017.2.5)
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
- ios-deploy not installed 按照提示执行brew install ios-deploy
[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[✓] Xcode - develop for iOS and macOS (Xcode 11.0)
[!] iOS tools - develop for iOS devices
✗ ios-deploy not installed. To install:
brew install ios-deploy
[✓] Android Studio (version 3.4)
[!] IntelliJ IDEA Ultimate Edition (version 2017.2.5)
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
[!] Connected device
! No devices available
二：Flutter IDE 配置
1：Android Studio或Viual Studio Code下载
2：Android Studio 在File>Setting>Plugins>MarketPlace中搜索Flutter，安装搜索结果第一条，成功后按提示重启
3：Android Studio File>Setting>Languages>Flutter中设置Flutter路径，/Users/yaodong/flutter
4： Android Studio File>Setting>Languages>Dart 中设置Dart SDK，/Users/yaodong/flutter/bin/cache/dart-sdk(第一步已直接设置好，检查即可)
三：最终运行flutter doctor
[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[✓] Xcode - develop for iOS and macOS (Xcode 11.0)
[✓] iOS tools - develop for iOS devices
[✓] Android Studio (version 3.4)
[!] IntelliJ IDEA Ultimate Edition (version 2017.2.5)
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
[!] Connected device
! No devices available
1：因为我安装了IntelliJ IDEA，所以提示我需要配置flutter环境变量
2：未连接真机或者未生成模拟器，会提示No devices available
四：工程运行
1：File>New>New Flutter Project
2：运行（连接真机或新建模拟器即可）
