An expressive way to effortlessly build design systems in Flutter.
Example #
Mix provides a lot of different benefits on how you can define and organize your design tokens, and no documentation would be complete without a syntax comparison between Mix vs. Without Mix.
Let's go ahead and take a look at the code. Don't worry about understanding each line, the docs will go into more detail about each item.
With Mix #
class CustomMixWidget extends StatelessWidget {
const CustomMixWidget({super.key});
@override
Widget build(BuildContext context) {
final style = Style(
height(100),
marginVertical(10),
elevation(10),
borderRadius(10),
backgroundColor($md.colorScheme.primary()),
text.style($button()),
text.style.color($md.colorScheme.onPrimary()),
onHover(
elevation(2),
padding(20),
backgroundColor($md.colorScheme.secondary()),
text.style.color($md.colorScheme.onSecondary()),
),
);
return Box(
mix: style,
child: const TextMix('Custom Widget'),
);
}
}
Without Mix #
class CustomWidget extends StatefulWidget {
const CustomWidget({
super.key,
});
@override
_CustomWidgetState createState() => _CustomWidgetState();
}
class _CustomWidgetState extends State<CustomWidget> {
bool _isHover = false;
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
final colorScheme = Theme.of(context).colorScheme;
return MouseRegion(
onEnter: (event) {
setState(() => _isHover = true);
},
onExit: (event) {
setState(() => _isHover = false);
},
child: Material(
elevation: _isHover ? 2 : 10,
child: AnimatedContainer(
curve: Curves.linear,
duration: const Duration(milliseconds: 100),
height: 100,
padding:
_isHover ? const EdgeInsets.all(20) : const EdgeInsets.all(0),
margin: const EdgeInsets.symmetric(vertical: 10),
decoration: BoxDecoration(
color: _isHover ? colorScheme.secondary : colorScheme.primary,
borderRadius: BorderRadius.circular(10),
),
child: Text(
'Custom Widget',
style: Theme.of(context).textTheme.button?.copyWith(
color: _isHover
? colorScheme.onSecondary
: colorScheme.onPrimary,
),
),
),
),
);
}
}
