LazyVGrid handles the layout, and cornerRadius(24) matches Apple's default widget styling perfectly.ZStack as the root of the widget to easily overlay content on top of complex gradients or images.class WidgetDesignScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(

crossAxisCount: 2, // 2 columns for a typical phone

Stack inside a Container with BorderRadius.circular(24) is the blueprint for every widget.GridView is too rigid for mixed 2x1 and 1x1 widgets. Use the flutter_staggered_grid_view package for production apps.const WidgetDesignScreen = () => {
return (
<ScrollView style={{ flex: 1, backgroundColor: '#F2F2F2' }} contentContainerStyle={{ padding: 24 }}>
<View style={{ flexDirection: 'row', flexWrap: 'wrap', justifyContent: 'space-between', gap: 16 }}>
{/* 2x1 Widget (Full width minus padding) */}
<View style={[styles.widget, { width: '100%' }]}>
<LinearGradient colors={['#4facfe', '#00f2fe']} style={styles.widgetBg} />
<Text style={styles.temp}>72°</Text>
<Text style={styles.sub}>San Francisco</Text>
</View>
{/* 1x1 Widgets (Half width minus half gap) */}
<View style={[styles.widget, { width: '47%' }]}><Text>Fitness</Text></View>
<View style={[styles.widget, { width: '47%' }]}><Text>Music</Text></View>
</View>
</ScrollView>
);
};
const styles = StyleSheet.create({
widget: {
height: 160, // Fixed height forces square/rectangular aspect ratios
borderRadius: 24,
backgroundColor: '#FFF',
padding: 16,
justifyContent: 'flex-end',
shadowColor: '#000', shadowOffset: { width: 0, height: 5 }, shadowOpacity: 0.1, shadowRadius: 10, elevation: 5,
overflow: 'hidden'
},
widgetBg: {
...StyleSheet.absoluteFillObject,

},
temp: { fontSize: 48, fontWeight: '300', color: '#FFF' },
sub: { fontSize: 14, color: 'rgba(255,255,255,0.8)' }
});
flexWrap: 'wrap' combined with percentage widths (e.g., 47% for 2 columns with a gap) is the cleanest way to build a responsive widget layout.LinearGradient from expo-linear-gradient or react-native-linear-gradient, apply StyleSheet.absoluteFillObject so it sits behind the text.@Composable

LazyVerticalGrid with GridCells.Fixed(2) and GridItemSpan perfectly recreate iOS widget grids.RoundedCornerShape(24.dp) is essential to sell the look.tools

Builds two parameterized UI modes—流光溢彩白 (iridescent white) and 五彩斑斓黑 (colorful black)—with OKLCH, WebGL/CSS fallback, vision gating, screenshot QA, and total/per-color intensity reports. Use when a UI request names either mode or needs measured color parameters.
