height property

@override double height

Constructs a TextPainter and uses the calculated TextPainter.height with the defaultPadding to calculate the height of the widget.

Implementation

@override
double get height =>
    (TextPainter(
      text: TextSpan(
        text: title,
        style: textStyle ?? TextStyle(fontWeight: defaultFontWeight),
      ),
      maxLines: 1,
    )..layout())
        .height +
    defaultPadding * 2;
