Implement WCAG 2 and EN 301 549 accessibility standards and adaptive layouts in Flutter apps. Implements, audits, and enforces accessibility (a11y) and adaptive design standards in Flutter applications. Ensures compliance with WCAG 2 and EN 301 549 by applying proper semantic roles, contrast ratios, tap target sizes, and assistive technology integrations. Constructs adaptive layouts that respond to available screen space and input modalities (touch, mouse, keyboard) without relying on hardware-specific checks or locked orientations. When implementing UI components, follow this decision tree to determine the required accessibility and adaptive design implementations: Initialize Web Accessibility (If Applicable) For web targets, accessibility is disabled by default for performance. Force enable it at the entry point. Apply Semantic Annotations Use Semantics , MergeSemantics , and ExcludeSemantics to build a clean accessibility tree. For custom web components, explicitly define the SemanticsRole .
