Question

I am getting this error in my project. I even created a new plain flutter project but I am getting the same error for that too.

But still it dowent workRunning "flutter pub get" in abccdddd... 1.0s Launching lib\\main.dart on SM J600G in debug mode... Running Gradle task 'assembleDebug'...

Answer 1

I opened .pub-cache/hosted/pub.dartlang.org/cupertino_icons-0.1.3/lib/placeholder.txt file and cleared it. And it started working for me. Really odd, but it did.
