build method

@override Widget build({ required Animation<double> animation, required Widget child, Map<String, Object?> params = const {}, })

Builds the animated widget for the forward direction.

animation — 0.0 → 1.0 where 0.0 = invisible/start, 1.0 = visible/end. child — the widget being animated. params — optional configuration map (typed by each plugin).

Concrete subclasses must override this method.

Implementation

@override
Widget build({
  required Animation<double> animation,
  required Widget child,
  Map<String, Object?> params = const {},
}) {
  final waveHeight = (params['waveHeight'] as double?) ?? 20.0;
  final waveCount = (params['waveCount'] as double?) ?? 1.5;
  final fromBottom = (params['fromBottom'] as bool?) ?? true;

  return AnimatedBuilder(
    animation: animation,
    builder: (_, c) => ClipPath(
      clipper: _LiquidClipper(
        t: animation.value,
        waveHeight: waveHeight,
        waveCount: waveCount,
        fromBottom: fromBottom,
      ),
      child: c,
    ),
    child: child,
  );
}
