Flutter sample app not working

Question

Today I started development in Flutter. I have completed setup and installation process. When I try to run sample app created by following steps mentioned here.

I don't know what can be problem/Issue.

But output look like this in Android Emulator.

Answer 1

I assume it is an issue with hardware rendering in the emulator.

If it actually is the problem you should be able to work around with

flutter run --enable-software-rendering -t lib/main.dart 

(-t lib/main.dart is default and optional)
