responsive-layout SKILL.md skillA
responsive-layout from smicolon/ai-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Builds responsive and adaptive Flutter user interfaces across mobile, tablet, desktop, and web form factors using LayoutBuilder, MediaQuery, and adaptive breakpoints.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Responsive Layout in Flutter
Techniques for building cross-platform Flutter layouts that adapt to phones, tablets, foldables, and desktops.
## Breakpoint System
```dart
class ResponsiveBreakpoints {
static const double mobile = 600;
static const double tablet = 900;
static const double desktop = 1200;
static bool isMobile(BuildContext context) =>
MediaQuery.sizeOf(context).width < mobile;
static bool isTablet(BuildContext context) =>
MediaQuery.sizeOf(context).width >= mobile &&
MediaQuery.sizeOf(context).width < desktop;
static bool isDesktop(BuildContext context) =>
MediaQuery.sizeOf(context).width >= desktop;
}
```
## Pattern 1: `LayoutBuilder` for Component Adaptability
Use `LayoutBuilder` when a component should adapt based on its parent container's width, rather than the entire screen:
```dart
class AdaptiveCardList extends StatelessWidget {
const AdaptiveCardList({super.key});
@override
Widget build(BuildContext context) {
return LayoutBuilder(
builder: (context, constraints) {
if (constraints.maxWidth > 800) {
// Grid layout on wide containers
return GridView.builder(

How to install
mdr add smicolon/ai-kit/responsive-layout@sha256:d3266d03b4f0f4d9The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
