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.

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<

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.
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 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.
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?
-
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
