推荐答案

在某些计算机中，您需要以管理员身份打开命令提示符.因此，您可以尝试以下步骤并检查

In some machines, you need to open the command prompt as an administrator. So, you can try out the following steps and check

• 以管理员身份执行命令提示符.
• 运行命令 flutter doctor --android-licenses 并接受所有命令.通过按 Y 来获得许可.
• 运行命令 flutter doctor -v 来检查问题是否仍然存在；
• 以常规用户身份登录，然后尝试 flutter doctor -v 以确保一切正常.

• Execute command prompt as administrator.
• Run the command flutter doctor --android-licenses and accept all. licenses by pressing Y.
• Run the command flutter doctor -v to check whether the issue is still there;
• Login as a regular user and try flutter doctor -v to make sure everything is okay.

如果仍然给您同样的问题，请访问flutter文件夹并打开名为 flutter_console.bat 的文件，然后键入以下命令 flutter doctor --android-licenses .

If it still giving you the same issue visit your flutter folder and open the file called flutter_console.bat and type this command flutter doctor --android-licenses.
