AutoSizeText class

Flutter widget that automatically resizes text to fit perfectly within its bounds.

All size constraints as well as maxLines are taken into account. If the text overflows anyway, you should check if the parent widget actually constraints the size of this widget.

Properties

data → String
The text to display. [...]
final
group AutoSizeGroup
Synchronizes the size of multiple AutoSizeTexts. [...]
final
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 resized according to the specified bounds and if necessary truncated according to overflow. [...]
final
minFontSize → double
The minimum text size constraint to be used when auto-sizing text. [...]
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
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
If non-null, the style to use for this text. [...]
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
textSpan TextSpan
The text to display as a TextSpan. [...]
final
wrapWords → bool
Whether words which don't fit in one line should be wrapped. [...]
final
hashCode → int
The hash code for this object.
read-only, inherited
key Key
Controls how one widget replaces another widget in the tree. [...]
final, inherited
runtimeType → Type
A representation of the runtime type of the object.

Methods

createState() → _AutoSizeTextState
Creates the mutable state for this widget at a given location in the tree. [...]
override
createElement() StatefulElement
Creates a StatefulElement to manage this widget's location in the tree. [...]
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children. [...]
@protected, inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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.debug }) → String
Returns 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.
