Core Concepts
Responsive
Responsive breakpoints based on Tailwind CSS for adaptive layouts.
Forui contains responsive breakpoints based on Tailwind CSS.
Predefined Breakpoints
All breakpoints are in logical pixels. Mobile devices are typically smaller than sm (640), while tablet and desktop
devices are typically larger than md (768) and lg (1024) respectively.
| Breakpoint | Minimum width | Accessor |
|---|---|---|
sm | 640 | FThemeData.breakpoints.sm |
md | 768 | FThemeData.breakpoints.md |
lg | 1024 | FThemeData.breakpoints.lg |
xl | 1280 | FThemeData.breakpoints.xl |
xl2 | 1536 | FThemeData.breakpoints.xl2 |
Usage
1@override2Widget build(BuildContext context) {3 final breakpoints = context.theme.breakpoints;4 final width = MediaQuery.sizeOf(context).width;56 return switch (width) {7 _ when width < breakpoints.sm => const MobileWidget(),8 _ when width < breakpoints.lg => const TabletWidget(),9 _ => const DesktopWidget(),10 };11}12Custom Breakpoints
Additional breakpoints can be added via an extension on FBreakpoints:
1extension CustomBreakpoints on FBreakpoints {2 double get custom => 42;3}4After which, the custom breakpoint can be accessed like so:
1@override2Widget build(BuildContext context) {3 final breakpoints = context.theme.breakpoints;4 final width = MediaQuery.sizeOf(context).width;56 return switch (width) {7 _ when width < breakpoints.custom => const SuperSmallWidget(),8 _ when width < breakpoints.sm => const MobileWidget(),9 _ when width < breakpoints.lg => const TabletWidget(),10 _ => const DesktopWidget(),11 };12}13
