CLI (Command-line tool)
Flutter 是 Google 开发的一个跨平台移动应用程序开发框架，它可以让开发者使用一种代码库开发 iOS 和 Android 应用。在使用 Flutter 开发应用程序时，需要掌握一些常用的命令，下面是这些命令的详细介绍：
1.flutter create [projectName]
创建新的 Flutter 项目，需要指定项目名称。例如：flutter create my_app。
2.flutter run
运行 Flutter 应用程序，可以将应用程序运行在 iOS 模拟器、Android 模拟器或真实的设备上。例如：flutter run -d emulator-1。
3.flutter doctor
检查 Flutter 安装是否正确以及是否需要安装其他依赖项。例如：flutter doctor -v。
4.flutter build
构建 Flutter 应用程序，可以将应用程序构建成 Release 或 Debug 版本。例如：flutter build apk。
5.flutter clean
清除 Flutter 应用程序的构建缓存和临时文件。例如：flutter clean。
6.flutter packages get
获取应用程序依赖项的最新版本。例如：flutter packages get。
7.flutter packages upgrade
将应用程序依赖项升级到最新版本。例如：flutter packages upgrade。
8.flutter upgrade
将 Flutter 框架升级到最新版本。例如：flutter upgrade。
9.flutter format
格式化 Flutter 代码，可以使用该命令对代码进行自动格式化。例如：flutter format .。
10.flutter analyze
分析 Flutter 代码并输出警告和错误信息。例如：flutter analyze .。
11.flutter test
运行 Flutter 单元测试，可以使用该命令执行应用程序的测试。例如：flutter test。
以上是一些常用的 Flutter 命令，掌握这些命令可以更加高效地开发 Flutter 应用程序。
