build method

double build(double t)

Returns the value of the curve at the given progress.

t is the progress of the animation, ranging from 0.0 (start) to 1.0 (end).

Implementation

double build(double t) {
  switch (type) {
    case 'ease-in-out':
      return _EaseInOutCurve.build(t);
    case 'linear':
      return _LinearCurve.build(t);
    case 'ease-in':
      return _EaseInCurve.build(t);
    case 'ease-out':
      return _EaseOutCurve.build(t);
    case 'ease-in-out-back':
      return _EaseInOutBackCurve.build(t);
    case 'ease-out-back':
      return _EaseOutBackCurve.build(t);
    case 'bounce-in':
      return _BounceInCurve.build(t);
    case 'bounce-out':
      return _BounceOutCurve.build(t);
    default:
      throw UnimplementedError(
        'Unknown curve type: $type',
      );
  }
}
