准备的软件：
最新版的 Android Studio 安装文件夹下的 jre 文件夹是自带的 OpenJDK 11.0.10, 我从另外一台安装有 Android Studio 的电脑上复制了这个文件夹并改名为 openJDK 备用
说明：理论上搭建 Flutter 开发环境只要有 Android SDK 就可以了, 可以不安装 Android Studio。 于是找了个旧电脑来试了一下。当然了, 在开发完整功能的 Flutter 应用程序时, 如果需要编写涉及 Android 的混合代码, 还是配合使用 Android Studio 更方便。
配置 Flutter SDK 使用国内镜像 由于某些不可描述的原因，Flutter SDK 的资源网站访问受到影响，可以通过设置 PUB_HOSTED_URL 和 FLUTTER_STORAGE_BASE_URL 两个环境变量设置为使用国内镜像， 以下两个站点二选一：
使用清华大学镜像： 使用管理员权限打开 CMD窗口 或 PowerShell窗口，执行以下命令：
1 2 setx "PUB_HOSTED_URL" "https://mirrors.tuna.tsinghua.edu.cn/dart-pub" setx "FLUTTER_STORAGE_BASE_URL" "https://mirrors.tuna.tsinghua.edu.cn/flutter"
使用Flutter官方为中国开发者搭建了临时镜像： 使用管理员权限打开 CMD窗口 或 PowerShell窗口，执行以下命令：
1 2 setx "PUB_HOSTED_URL" "https://pub.flutter-io.cn" setx "FLUTTER_STORAGE_BASE_URL" "https://storage.flutter-io.cn"
配置 Flutter SDK
打开文件夹 D:\AppData (没有则新建一个, 或指定其他合适的文件夹)
将下载好的 Flutter SDK 压缩文件复制到该文件夹中，使用 解压到当前位置 解压文件, Flutter SDK 的路径为：D:\AppData\flutter
修改环境变量 path， 添加一个值: D:\AppData\flutter\bin (如果使用命令方式修改环境变量，与下一步的 配置JDK 一起修改)
配置 JDK
打开 D:\AppData 文件夹
将 openJDK 复制该文件中, JDK 的路径为：D:\AppData\openJDK
添加环境变量 JAVA_HOME: 使用 管理员权限 打开 CMD窗口 或 PowerShell窗口，执行以下命令：
1 setx "JAVA_HOME" "D:\AppData\openJDK" /m
修改环境变量 path, 添加两个值：%JAVA_HOME%\bin 和 %JAVA_HOME%\jre\bin, 使用管理员权限打开 CMD窗口 或 PowerShell窗口，执行以下命令：
1 setx PATH "%PATH%;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;D:\AppData\flutter\bin" /m
将下载好的 commandlinetools-win-8092744_latest.zip (当前最新版) 文件解压缩, 修改解压后的文件夹名称及相关路径为以下格式： D:\AppData\Android\Sdk\cmdline-tools\latest, 确保 latest 文件夹内为 bin 、lib 文件夹, 如下图所示:
特别提醒: 文件夹路径不对, 会导致后续步骤不能正确执行, D:\AppData\Android\Sdk\ 为 Android SDK 路径, 可根据自己的需要进行修改调整; cmdline-tools\latest 为Android SDK内部文件夹结构, 不能变动。
添加ANDROID_HOME 环境变量
将 Android SDK 的路径添加到环境变量中, 使用 管理员权限 运行 CMD窗口 或 PowerShell窗口, 执行以下命令：
1 setx "ANDROID_HOME" "D:\AppData\Android\Sdk" /m
将 D:\AppData\Android\Sdk 替换为自己电脑实际的 Android SDK 路径
在 D:\AppData\Android\Sdk\cmdline-tools\latest\bin 文件夹打开 Powershell 或 CMD 窗口
查看 已安装的包 和 有效的包, 命令格式： sdkmanager.bat --list, Powershell窗口 执行情况如下所示：

安装 Android SDK 软件包
安装命令: sdkmanager <packages>
这里至少需要安装三个组件： platform-tools、 build-tools、 platforms
命令：./sdkmanager "platform-tools" "build-tools;30.0.3" "platforms;android-34"
说明: 不同版本的 Flutter SDK 要求的这三个组件的版本会有所不同, 如果不知道具体的版本需求, 可以按以上版本进行安装, 等项目运行时, Flutter 会自动下载正确的版本。
Flutter 3.16.x 需要 Android SDK Platform 33,命令可以更改为： ./sdkmanager "platform-tools" "build-tools;30.0.3" "platforms;android-33"
