This article provides a practical guide to Flutter accessibility, focusing on the fundamental concepts and tools for building accessible applications. It highlights the importance of accessibility, not just for legal compliance but also for creating better user experiences. The core of Flutter’s accessibility is the Semantics widget, which provides an invisible layer of information for assistive technologies. The article explains how to use Semantics to add labels, hints, values, roles, and actions to widgets. It also addresses the “double announcement” problem and introduces the MergeSemantics widget to solve it by combining semantic information from multiple widgets into a single node. Finally, it covers essential testing tools like TalkBack for Android and VoiceOver for iOS.
