Semantic Labels
// Icons & buttons
Semantics(label: 'Settings', button: true, child: Icon(Icons.settings))
// Images (or ExcludeSemantics if decorative)
Semantics(label: 'Profile picture', image: true, child: Image.network(url))
// Interactive (prefer InkWell over GestureDetector)
Semantics(button: true, label: 'Open', child: InkWell(...))Dynamic Announcements
import 'package:flutter/semantics.dart';
SemanticsService.announce('Button unlocked!', TextDirection.ltr);Touch Targets & Forms
// Minimum 48x48 dp
IconButton(iconSize: 48, ...)
// Forms need labels
TextField(decoration: InputDecoration(
labelText: 'Email',
errorText: isValid ? null : 'Invalid',
))Color Contrast
// Use ColorPalette (WCAG-compliant)
Text('Text', style: TextStyle(
color: ColorPalette.coloursBasicText.platformBrightnessColor(context),
))Focus Management
FocusTraversalGroup(
policy: OrderedTraversalPolicy(),
child: Column(children: [
FocusTraversalOrder(order: NumericFocusOrder(1), child: TextField(...)),
FocusTraversalOrder(order: NumericFocusOrder(2), child: Button(...)),
]),
)Testing
// Automated
await expectLater(tester, meetsGuideline(textContrastGuideline));
await expectLater(tester, meetsGuideline(androidTapTargetGuideline));Checklist
- Semantic labels on interactive elements
- Touch targets ≥ 48x48 dp
- Contrast ≥ 4.5:1 (text), 3:1 (UI)
- Forms have labels + errors
- Dynamic changes announced
- Logical focus order
- Tested with VoiceOver + TalkBack
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
