A practical introduction to Flutter accessibility using built-in tools. Covers the Semantics widget for adding labels, hints, and state flags to silent controls like IconButton, and the MergeSemantics widget for fixing double-announcement issues caused by overlapping semantic nodes. Includes testing guidance using TalkBack, VoiceOver, Android Ally plugin, Google Accessibility Scanner, and Xcode Accessibility Inspector. Also draws comparisons to Jetpack Compose and SwiftUI accessibility APIs, and touches on legal requirements like the EU Accessibility Act and ADA.
