Flutter环境搭建以及快捷命令

Flutter环境搭建

• 配置环境变量

  用户变量

  FLUTTER_STORAGE_BASE_URL : https://storage.flutter-io.cn

  PUB_HOSTED_URL : https://pub.flutter-io.cn

  由于是在国内，所以需要配置一个可靠的镜像站点，也可以选择清华大学TUNA

  FLUTTER_STORAGE_BASE_URL: https://mirrors.tuna.tsinghua.edu.cn/flutter

  PUB_HOSTED_URL: https://mirrors.tuna.tsinghua.edu.cn/dart-pub

• 获取Flutter SDK

  下载链接：https://flutter.dev/docs/development/tools/sdk/releases#windows

  可以直接下载SDK然后解压，也可以从github下载，目前最新版v1.12.13+hotfix.7

  在系统变量中编辑用户变量的Path条目，添加flutter SDK的bin目录

  Path : D:\flutter\sdk\bin

• 运行 flutter doctor

  1,安装Android Studio （为了安装Android SDK）

  2,安装VS Code 和 Android Studio 的Dart,Flutter插件

  3,(非必须)安装安卓模拟器Android Studio>Tools>AVD Manager

  4,如果是真机调试，开启开发人员选项 和 USB调试。

  5,安装java jdk,配置环境变量

终端运行flutter doctor，显示No issues found ，环境搭建ok。

创建flutter项目，获取pubspec.yaml中的依赖包，运行项目

flutter create 创建项目

flutter pub get 获取依赖

flutter run 运行项目

创建，查看，启动模拟器

flutter emulators --create --name 模拟器名称

flutter emulators 查看所有模拟器

flutter emulators --launch 模拟器名称

Android Studio > Tools > AVD Manager 手动删除或者创建模拟器

检查，更新flutter

flutter doctor 显示flutter相关状态

flutter upgrade 更新flutter
