I’m working on a Flutter application where I have a ListView.separated widget. When I click the “Load More” button, I fetch new data from my controller and append it to the list. However, I want the ListView to automatically scroll down to the bottom to show the newly loaded data.
Here is the code I’m currently using:
onPressed: () async {
await controller.setSkip(controller.products.length);
controller.getProducts();
scrollController.animateTo(
scrollController.position.extentTotal,
duration: const Duration(milliseconds: 300),
curve: Curves.easeOut,
);
}
Despite using this code, the ListView doesn’t scroll to the bottom as expected. I’ve tried various approaches, but none seem to work. What alternative methods can I try to ensure the ListView scrolls to the bottom when new data is added?
Thank you for your help!
