this is a simple android project that demonstrates how to add an aar file in flutter and run a flutter app from native android code.
Just run the app on any android device/emulator and click on Hello World text view to launch the flutter aar on from the MainActivity. (app/src/main/java/com/ashank/fluttersdk/MainActivity.java)
the standard path for an aar file is project-name/module-name/build/outputs/aar/
