flutter build apk 反复安装平台工具

Question

我已经在 windows-10 上安装了 flutter 和 android-SDK（没有 android studio）。安装成功完成，一切正常，网络上没有错误，但是当我运行 flutter build apk 它会抛出一些警告

它开始下载 platform-tools 、 build-tools 和 emulator （如果已经存在，它仍然会像 platform-tools-2 、 build-tools-2 和 emulator-2 一样一次又一次地下载）

我的flutter doctor -v是

显然您只需要正确设置 android sdk 文件结构。我制作了这个后续视频，展示了要遵循的步骤。 The Video

或按照以下步骤操作：

安装flutter sdk 和 java jdk 并将主题添加到系统的环境变量中。
前往 https://developer.android.com/studio#command-tools 并仅下载命令行工具并将 zip 文件解压缩到 c:\ANDROID-SDK 将其添加到环境变量 'ANDROID_SDK_ROOT' : "c:\ANDROID-SDK"
现在在CMD中打开如下路径"C:\ANDROID-SDK\cmdline-tools\bin"
运行命令sdkmanager.bat "cmdline-tools;latest" --sdk_root=../../
现在将其添加到您的环境变量路径“C:\ANDROID-SDK\cmdline-tools\latest\bin”
接下来打开CMD安装build-tools "sdkmanager.bat "build-tools;30.0.3" "
然后平台sdkmanager.bat "platforms;android-31"
现在运行flutter config --android-sdk %ANDROID_SDK_ROOT%
运行 flutter doctor --android-licenses 并接受许可。
现在去你的项目运行flutter build apk
