Solve the Flutter Outline shows "Nothing to show" in Android Studio

 

Solution: Click on the red recycle icon of the Dart Analysis windows

Have you wondered why the Flutter Outline doesn't show anything? I googled it and found many answers. Strangely the accepted answer on stackoverflow.com, which has got 144 helpful votes, doesn't actually solve the issue, especially in my case. Therefore I wrote about it here to help other people.

As you can see in that link above, there are 9 answers to that particular questions. In my case, only two actually work i.e. clicking on red recycle icon in the Dart Analysis window. 

Here we are folks. As a programmer you wasted a lot of time googling and try any solution written, which most of the time don't work. Only after trying many things you may hit the correct one!

Cheers!
