Implementation

@override
void initAnimation(AnimationController controller) {
  final direction = textDirection;

  const double inIntervalEnd = 1.0;

  _slideIn = AlignmentTween(
    begin: Alignment.topCenter.add(alignment).resolve(direction),
    end: Alignment.center.add(alignment).resolve(direction),
  ).animate(
    CurvedAnimation(
      parent: controller,
      curve: const Interval(0.0, inIntervalEnd, curve: Curves.linear),
    ),
  );

  _fadeIn = Tween<double>(begin: 0.0, end: 1.0).animate(
    CurvedAnimation(
      parent: controller,
      curve: const Interval(0.0, inIntervalEnd, curve: Curves.easeOut),
    ),
  );
}
