innerAnimateTo method

Future innerAnimateTo({ required int index, required Duration duration, required Curve curve, EdgeInsets padding = EdgeInsets.zero, BuildContext? sliverContext, bool isFixedHeight = false, double alignment = 0, ObserverLocateIndexOffsetCallback? offset, ObserverRenderSliverType? renderSliverType, })

Jump to the specified index position with animation.

If the height of the child widget and the height of the separator are fixed, please pass the isFixedHeight parameter and the renderSliverType parameter.

The renderSliverType parameter is used to specify the type of sliver. If you do not pass the renderSliverType parameter, the sliding position will be calculated based on the actual type of obj, and there may be deviations in the calculation of elements for third-party libraries.

The alignment specifies the desired position for the leading edge of the child widget. It must be a value in the range 0.0, 1.0.

Implementation

Future innerAnimateTo({
  required int index,
  required Duration duration,
  required Curve curve,
  EdgeInsets padding = EdgeInsets.zero,
  BuildContext? sliverContext,
  bool isFixedHeight = false,
  double alignment = 0,
  ObserverLocateIndexOffsetCallback? offset,
  ObserverRenderSliverType? renderSliverType,
}) {
  Completer completer = Completer();
  _scrollToIndex(
    completer: completer,
    index: index,
    isFixedHeight: isFixedHeight,
    alignment: alignment,
    padding: padding,
    sliverContext: sliverContext,
    duration: duration,
    curve: curve,
    offset: offset,
    renderSliverType: renderSliverType,
  );
  return completer.future;
