AutoSizeText class Null safety

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.

Creates a AutoSizeText widget.
const
AutoSizeText.rich(TextSpan textSpan, {Key? key, Key? textKey, TextStyle? style, StrutStyle? strutStyle, double minFontSize = 12, double maxFontSize = double.infinity, double stepGranularity = 1, List<double>? presetFontSizes, AutoSizeGroup? group, TextAlign? textAlign, TextDirection? textDirection, Locale? locale, bool? softWrap, bool wrapWords = true, TextOverflow? overflow, Widget? overflowReplacement, double? textScaleFactor, int? maxLines, String? semanticsLabel})

Properties

data String?
The text to display.
final
group AutoSizeGroup?
Synchronizes the size of multiple AutoSizeTexts.
final
hashCode int
The hash code for this object.
@nonVirtualread-onlyinherited
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 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
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
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
textKey Key?
Sets the key for the resulting Text widget.
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
