How to use the PI constant in Dart

Question

I imported math.

import 'dart:math'; 

But how can I call "PI" constant?

This is not working.

   math.pi / 12.0 

Answer 1

you should import 'dart:math' as math; instead of just import 'dart:math';

because when you use the as keyword you provide the imported library a name so you can reference it anywhere in your file
