是否可以在Flutter应用中添加Android支持库。尝试将Android Support v13：27.11添加到Flutter应用程序时遇到了此错误。显示的错误为“成绩同步失败”
我尝试添加和删除该库，但是只有在添加该库时构建才会失败。
显示的确切错误是：
Gradle Sync Failed
我使用了支持库来启用Android通知。如果还有其他图书馆可以提供帮助，我也可以免费尝试。
更新： 我在Build.gradle
中添加了以下内容implementation "com.android.support:support-compat:27.0.0"
implementation "com.android.support:support-media-compat:27.1.1"
和日志是
