animateToYearPicker method

Future<void> animateToYearPicker([ DateTime? date, Duration duration = const Duration(milliseconds: 200), Curve curve = Curves.ease ])

Shows the year picker for the given date's year, or the current year if date is null.

If the year picker is already shown, its grid animates to the decade; otherwise it is shown immediately.

Implementation

Future<void> animateToYearPicker([
  DateTime? date,
  Duration duration = const Duration(milliseconds: 200),
  Curve curve = Curves.ease,
]) async {
  final target = _clamp(start, switch (date) {
    null => _currentMonth,
    final m => .utc(m.year, m.month),
  }, end);

  if (year.controller.hasClients) {
    await year.animateTo(target, duration: duration, curve: curve);
  } else {
    _reattach(year, .year, target);
  }
}
