Answer 2

Replace the line with includeBuild in settings.gradle similarly to this:

includeBuild(file("${settings.ext.flutterSdkPath}/packages/flutter_tools/gradle").toPath().toRealPath().toAbsolutePath().toString())

Answer 3

I landed on this question while looking for help on the same error but while loading a react-native project. In my case it was due to an android plugin that I was able to work around. See the full solution here -
