Constructors
- ExpandableText.lines(String text, {required int? lines, Color? arrowColor, double arrowSize = 24, ArrowBuilder? arrowWidgetBuilder, Duration animationDuration = const Duration(milliseconds: 150), TextStyle? textStyle, StrutStyle? strutStyle, TextAlign textAlign = TextAlign.start, TextDirection textDirection = TextDirection.ltr, Locale? locale, double textScaleFactor = 1, TextWidthBasis textWidthBasis = TextWidthBasis.parent, bool expand = false, Alignment alignment = Alignment.topCenter, Key? key})
-
Auto control
Collapse text to max lines.
If the text's line <
maxLines, then will show text directly - ExpandableText.manual(String text, {required bool expand, required TickerProvider? vsync, Duration animationDuration = const Duration(milliseconds: 150), TextStyle? textStyle, StrutStyle? strutStyle, TextAlign textAlign = TextAlign.start, TextDirection textDirection = TextDirection.ltr, Locale? locale, double textScaleFactor = 1, TextWidthBasis textWidthBasis = TextWidthBasis.parent, Alignment alignment = Alignment.topCenter, Key? key})
- Manual control Show and hide text completely
- ExpandableText.showHide(String text, {Color? arrowColor, double arrowSize = 24, ArrowBuilder? arrowWidgetBuilder, Duration animationDuration = const Duration(milliseconds: 150), TextStyle? textStyle, StrutStyle? strutStyle, TextAlign textAlign = TextAlign.start, TextDirection textDirection = TextDirection.ltr, Locale? locale, double textScaleFactor = 1, TextWidthBasis textWidthBasis = TextWidthBasis.parent, bool expand = false, Alignment alignment = Alignment.topCenter, Key? key})
- Auto control Show and hide text completely. With a arrow at the bottom.
