SDK version incompatibility

[BuddhiLW]

When ever I add flutter-mx to the dependencies of a new project:

        kennytilton/flutter-mx
        {:git/url "https://github.com/kennytilton/flutter-mx.git"
         :sha "dbf5e5795f7ccb447b4cd18e37dcfb4d1dec23ab"}

I get:

Launching flutter run
Launching lib/main.dart on sdk gphone64 x86 64 in debug mode...
Running Gradle task 'assembleDebug'...                          
Warning: SDK processing. This version only understands SDK XML versions up to 3 but an SDK XML file of version 4 was encountered. This can happen if you use versions of Android Studio and the command-line tools that were released at different times.

Any ideas how I can navigate this issue?
