Results for “Semantics”

SemanticsProperties.focusable` and `SemanticsConfiguration.isFocusable` parameters were deprecated in favor of the `SemanticsProperties.focused` and `SemanticsConfiguration.isFocused` parameters. The `SemanticsConfiguration.isFocusable` property is deprecated in favor of `SemanticsConfiguration.isFocused`. This property is a nullable

import 'package:material_ui/material_ui.dart'; void main() { testWidgets('example test', (WidgetTester tester) async { final SemanticsHandle handle

properties and their related APIs were removed. The following properties are removed `SemanticsConfiguration.elevation`, `SemanticsConfiguration.thickness`, `SemanticsNode.thickness`, `SemanticsNode.elevation`, and `SemanticsNode.elevationAdjustment`. Both elevation and thickness semantics properties were created

Flutter now applies the semantic label of `button` to all interactive Material Chips for accessibility purposes. The outermost `Semantics` widget that wraps all Chip classes

platform implementations: If your code previously used `Semantics(header: true, ...)` or `SemanticsProperties(header: true, ...)` to declare headings, migrate your code to use `headingLevel: 1` (or another integer

corresponding semantics tree before this change should look like this: ```dart SemanticsNode#0 │ ├─SemanticsNode#1 │ │ │ └─SemanticsNode#5 │ │ flags: hasImplicitScrolling │ │ scrollChildren
