createBoxPainter method

  1. @override
BoxPainter createBoxPainter([
  1. VoidCallback? onChanged
])
override

Returns a BoxPainter that will paint this decoration.

The onChanged argument configures BoxPainter.onChanged. It can be omitted if there is no chance that the painter will change (for example, if it is a BoxDecoration with definitely no DecorationImage).

Implementation

@override
BoxPainter createBoxPainter([VoidCallback? onChanged]) {
  return _UnderlinePainter(
    decoration: this,
    onChanged: onChanged,
    animation: tabController?.animation,
    indicatorWidth: indicatorWidth,
    indicatorHeight: indicatorHeight,
  );
}
