animateToIndex method

void animateToIndex(int index, { required double itemExtent, Duration duration = const Duration(milliseconds: 300), Curves curve = Curves.easeInOut, })

Animates smoothly to a specific item index given a fixed itemExtent in pixels.

Animation will be ignored when duration is zero.

• if scroll direction is vertical, itemExtent is the computed height of an item in the scrollable component's children.
• if scroll direction is horizontal, itemExtent is the computed width of an item in the scrollable component's children.

Example

final scrollController = ScrollController();
scrollController.animateToIndex(
  5,
  itemExtent: 100.0,
  duration: const Duration(milliseconds: 300),
  curve: Curves.easeInOut,
);

Implementation

void animateToIndex(
  int index, {
  required double itemExtent,
  Duration duration = const Duration(milliseconds: 300),
  Curves curve = Curves.easeInOut,
}) {
  animateTo(index * itemExtent, duration: duration, curve: curve);
}
