Methods

build(ParagraphBuilder builder, {TextScaler textScaler = TextScaler.noScaling, List<PlaceholderDimensions>? dimensions}) → void: Adds a placeholder box to the paragraph builder if a size has been calculated for the widget.
inherited
codeUnitAt(int index) → int?: Returns the UTF-16 code unit at the given index in the flattened string.
inherited
codeUnitAtVisitor(int index, Accumulator offset) → int?: Performs the check at each InlineSpan for if the index falls within the range of the span and returns the corresponding code unit. Returns null otherwise.
inherited
compareTo(InlineSpan other) → RenderComparison: Describe the difference between this span and another, in terms of how much damage it will make to the rendering. The comparison is deep.
inherited
computeSemanticsInformation(List<InlineSpanSemanticsInformation> collector) → void: Walks the InlineSpan tree and accumulates a list of InlineSpanSemanticsInformation objects.
inherited
computeToPlainText(StringBuffer buffer, {bool includeSemanticsLabels = true, bool includePlaceholders = true}) → void: PlaceholderSpans are flattened to a 0xFFFC object replacement character in the plain text representation when includePlaceholders is true.
inherited
debugAssertIsValid() → bool: In debug mode, throws an exception if the object is not in a valid configuration. Otherwise, returns true.
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
getSemanticsInformation() → List<InlineSpanSemanticsInformation>: Flattens the InlineSpan tree to a list of InlineSpanSemanticsInformation objects.
inherited
getSpanForPosition(TextPosition position) → InlineSpan?: Returns the text span that contains the given position in the text.
inherited
getSpanForPositionVisitor(TextPosition position, Accumulator offset) → InlineSpan?: Performs the check at each InlineSpan for if the position falls within the range of the span and returns the span if it does.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toPlainText({bool includeSemanticsLabels = true, bool includePlaceholders = true}) → String: Flattens the InlineSpan tree into a single string.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A brief description of this object, usually just the runtimeType and the hashCode.
inherited
visitChildren(InlineSpanVisitor visitor) → bool: Calls visitor on this WidgetSpan. There are no children spans to walk.
inherited
visitDirectChildren(InlineSpanVisitor visitor) → bool: Calls visitor for each immediate child of this InlineSpan.

Operators

operator ==(Object other) → bool: The equality operator.
