AutoSizeStyledText class

Text widget with formatting via tags.

Formatting is specified as xml tags. For each tag, you can specify a style, icon, etc. in the tags parameter.

Example:

StyledText(
  text: '<red>Red</red> text.',
  tags: [
    'red': StyledTextTag(style: TextStyle(color: Colors.red)),
  ],
)

Create a text widget with formatting via tags.

Properties

group → AutoSizeGroup?
Synchronizes the size of multiple AutoSizeTexts.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
locale → Locale?
Used to select a font when the same Unicode character can be rendered differently, depending on the locale.
final
maxFontSize → double
The maximum text size constraint to be used when auto-sizing text.
final
maxLines → int?
An optional maximum number of lines for the text to span, wrapping if necessary. If the text exceeds the given number of lines, it will be truncated according to overflow.
final
minFontSize → double
The minimum text size constraint to be used when auto-sizing text.
final
newLineAsBreaks → bool
Treat newlines as line breaks.
final
overflow → TextOverflow
How visual overflow should be handled.
final
overflowReplacement → Widget?
If the text is overflowing and does not fit its bounds, this widget is displayed instead.
final
presetFontSizes → List<double>?
Predefines all the possible font sizes.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticsLabel → String?
An alternative semantics label for this text.
final
softWrap → bool
Whether the text should break at soft line breaks.
final
stepGranularity → double
The step size in which the font size is being adapted to constraints.
final
strutStyle → StrutStyle?
The strut style to use. Strut style defines the strut, which sets minimum vertical layout metrics.
final
style → TextStyle?
Default text style.
final
styles → Map<String, TextStyle>
Style map for tags in text.
final
tags → Map<String, AutoSizeStyledTextTagBase>
Map of tag assignments to text style classes and tag handlers.
final
text → String
The text to display in this widget. The text must be valid xml.
final
textAlign → TextAlign
How the text should be aligned horizontally.
final
textDirection → TextDirection?
The directionality of the text.
final
textScaleFactor → double
The number of font pixels for each logical pixel.
final
wrapWords → bool
Whether words which don't fit in one line should be wrapped.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → _AutoSizeStyledTextState
Creates the mutable state for this widget at a given location in the tree.
override
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
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
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 short, textual description of this widget.
