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 Container(
    decoration: BoxDecoration(
      borderRadius: BorderRadius.circular(borderRadius),
      border: Border.all(
        color: backgroundColor,
        width: borderAnimation.value,
        strokeAlign: BorderSide.strokeAlignInside,
      ),
      color: kTransparent,
    ),
    padding: EdgeInsets.symmetric(
      vertical: verticalBorderAnimation.value,
      horizontal: horizontalBorderAnimation.value,
    ),
    child: child,
  );
}
