build method

@override Widget build(BuildContext context)

Override this method to build widgets that depend on the state of the listenable (e.g., the current value of the animation).

Implementation

@override
Widget build(BuildContext context) {
  return AnimatedBuilder(
    animation: animation,
    builder: (context, child) {
      return _BouncingCircleBgRenderObjectWidget(
        circles
            .map((e) => e.copyWith(
                width: ((e.max - e.min) * animation.value) + e.min))
            .toList(),
        child: child,
      );
    },
    child: child,
  );
}
