Flutter run on new location package throws error

Question

I have created a basic android flutter application using Android Studio. I remember running this app few times but all of a sudden it doesnt run. Tried changing the targetSdkVersion and compileSdkVersion from 27 to 28 as per few helps out there, but this did not work. Trying to understand the base of the problem since I am very new to Android development.

What I noticed: Below error is thrown only when I add geolocator or location package in pubspec.yaml and import it. If I remove it, the app works fine

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.

The error tells me you have not updated your compile SDK version. :) "android-27" means you're still using compile SDK version 27. Perhaps you forgot to save or something else is overriding it? It should be version 28.
