How to get theme color inside the widget in Flutter

Question

I have this:

Widget build(BuildContext context) {     return MaterialApp(       title: 'AnApp',       theme: ThemeData(         primarySwatch: Colors.blueGrey,       ),       home: MainWidget()     );   } } 

So I have set primarySwatch color to blueGrey. How can I access this color inside the MainWidget class?

I want to set a background the same as the AppBar color.

Answer 1

I'm not sure if there exist a way to use primarySwatch inside widget like that but if you are looking for AppBar color, it is actually the primaryColor and you can get it using

Color color = Theme.of(context).primaryColor;
