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.override -
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, {Locale? inheritedLocale, bool inheritedSpellOut = false}) → void -
Walks the InlineSpan tree and accumulates a list of
InlineSpanSemanticsInformation objects.
override
-
computeToPlainText(
StringBuffer buffer, {bool includeSemanticsLabels = true, bool includePlaceholders = true}) → void -
PlaceholderSpans are flattened to a
0xFFFC
object replacement character in the plain text representation whenincludePlaceholders
is true.override -
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.override -
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}) → 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.inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
