Why the upgrade to Flutter v0.7.3 beta stopped my application from running?

I have upgraded my Flutter version from 0.5.1 beta to 0.7.3 beta as few plugins were not working properly and I was suggested to upgrade to latest, both plugins and flutter itself. But, this has completely destroyed the application as it won't even start. Below is the Android Studio Run console output

I am sure the allElements() is not dart or flutter code. It's an inside Java code, means a plugin or Flutter itself is broken.

getAllElements()

allElements("activity")

flutter clean

I feel very embarrassed as it was my own doing which has brought this issue up. I finally fixed it by going to the Android manifest file and removed the offending

tools:replace="android:label"


which I had placed in the tag for whatever reason I don't know. Then I do..

flutter clean


Then Run the app works! Voila!
