您的Android sdk目录中似乎缺少必需的Android 27 API。请转到
~/library/android/sdk/tools/bin并运行sdkmanager --list以检查您是否安装了platform-tools和platforms;android-27。如果没有，则可以通过运行sdkmanager "platform-tools" "platforms;android-27"来安装它们如果你有Android Studio，那么你也可以通过Android Studio的GUI安装它们。

打开文件菜单---〉项目结构---〉项目设置---〉项目
检查您的项目SDK
另外，检查〉〉〉项目结构---〉平台设置---〉sdks
给予相同的SDK并单击“确定”
尝试运行项目

无需进行更改，除了您的主.dart页面代码加载新项目在Android工作室（如果您配置正确）复制粘贴https://www.tutorialspoint.com/flutter/flutter_creating_simple_application_in_android_studio.htm从提供的网址和运行主.dart所有问题都会得到解决

你应该离开默认的启动画面，因为它需要时间来加载程序！
