    當前最新穩定版：v1.7.8+hotfix.4

 

3、下載 android sdk

      http://www.androiddevtools.cn/

      在這個網站上下載 SDK Tools

      下載後解壓到 D:\software\android-sdk-windows文件夾

      運行 SDK Manager.exe 在彈出窗口中 以下選擇

      Tools 下選擇前三個

把 ;%ANDROID_SDK_HOME%\platform-tools;;%ANDROID_SDK_HOME%\tools 追加到系統環境變量Path中

 

4、flutter doctor

在 flutter 目錄下雙擊 flutter_console.bat 進入命令行，運行 flutter doctor 命令檢查 運行環境信息，若是沒安裝Dart則自動安裝

5、安裝過程當中碰到的問題

    1.Android license status unknown.

      首先 運行 flutter doctor --android-licenses，若是提示

A newer version of the Android SDK is required. To update, run:
D:\software\android-sdk-windows\tools\bin\sdkmanager --update

     則運行 D:\software\android-sdk-windows\tools\bin\sdkmanager --update ,若是提示

Warning: An error occurred during installation: Failed to move away or delete existing target file: D:\software\android-sdk-windows\tools
Move it away manually and try again..
done

    解決方法：進入 D:\software\android-sdk-windows 目錄，把tools文件夾改成tool，再運行 D:\software\android-sdk-windows\tool\bin\sdkmanager --update

   運行完成後會從新建立tools文件夾，把tools文件夾下的全部文件複製到tool文件夾後把文件夾名稱改成tools.

   再運行  flutter doctor --android-licenses
