Comment

To avoid such type of errors check if exist

if (_scrollController.hasClients) {
	_scrollController.animateTo(0.0, curve: Curves.easeOut, duration: const Duration(milliseconds: 300))
}

If this is false, then members that interact with the [ScrollPosition], such as
[position], [offset], [animateTo], and [jumpTo], must not be called.
