'Type 'Color' is not a subtype of 'MaterialColor' error appears every time I build my Flutter app on the simulator (Android and iOS) in Android Studio
If you want to use custom color from hex like this color 0xFF0E7AC7
const MaterialColor kPrimaryColor = const MaterialColor( 0xFF0E7AC7, const <int, Color>{ 50: const Color(0xFF0E7AC7), 100: const Color(0xFF0E7AC7), 200: const Color(0xFF0E7AC7), 300: const Color(0xFF0E7AC7), 400: const Color(0xFF0E7AC7), 500: const Color(0xFF0E7AC7), 600: const Color(0xFF0E7AC7), 700: const Color(0xFF0E7AC7), 800: const Color(0xFF0E7AC7), 900: const Color(0xFF0E7AC7), },);theme: ThemeData( primarySwatch: kPrimaryColor,),
