In Git branch A, I was trying some design tweaks when I thought about using Sliver List and then I wrote something like SliverList() and gave all the params that were required. I almost got that right but then I actually don't know exactly what happened but I was getting squiggly red lines underneath SliverList keyword although I didn't change anything. It mentioned something like Unnamed constructors Also I got the whole mobile screen red and decided not to waste anymore time on how to make it work since it wasn't the current priority so I removed SliverList widget from there and undo all of it.
But from then on I am not able to run my app. I am constantly getting this error:

I have tried flutter clean good loads of times but its not working. I am not sure where I am wrong and what to do about it. Another thing is that when I checkout to master, I Expected it to work since branch A is not merged. What exactly is the issue and how can I remove it?
