✨ What's new

1. Animate the lines

TimelineTile(
  alignment: TimelineAlign.manual,
  lineXY: 0.1,

  enableAfterLineAnimation: true,
  enableBeforeLineAnimation: true,
  tweenBeginColor: Colors.blue,
  tweenEndColor: Colors.red,

  isFirst: index == 0,
  isLast: index == examples.length - 1,
  indicatorStyle: IndicatorStyle(
    width: 40,
    height: 40,
    indicator: _IndicatorExample(number: '${index + 1}'),
    drawGap: true,
  ),
  beforeLineStyle: LineStyle(
    color: Colors.white.withOpacity(0.2),
  ),
  endChild: GestureDetector(
    child: _RowExample(example: example),
    onTap: () {
      Navigator.push(
        context,
        MaterialPageRoute<ShowcaseTimeline>(
          builder: (_) => ShowcaseTimeline(example: example),
        ),
      );
    },
  ),
);

2. Dotted and dashed lines

LineStyle now supports:

• dotted with dotRadius and dotSpacing
• isDashed with dashLength and dashSpacing

TimelineTile(
  beforeLineStyle: const LineStyle(
    color: Colors.blue,
    thickness: 4,
    isDashed: true,
    dashLength: 6,
    dashSpacing: 4,
  ),
  afterLineStyle: const LineStyle(
    color: Colors.blue,
    dotted: true,
    dotRadius: 2,
    dotSpacing: 6,
  ),
);
