Exception: Gradle task assembleDebug failed with exit code 1

on searching internet i came to know that it can resolved by changing compilesdkversion in android/app/buld.gradle from 27 to 28 link

after doing above chnages though it ran but shows blank white screen on emulator.

Hi @shu8hamrajput, I just tried the source code today, and it works fine on the latest flutter and Android Studio. Although, I did encounter the problem you were talking about as well, but that was from the source codes downloaded here: manning.com/books/flutter-in-action

This repo contains a more updated version.
