Flutter Tutorial - Adding Pagination with a NotificationListener widget and ScrollNotifications

#Flutter #TensorProgramming #FlutterPagination

In this Tutorial, we look at how to implement Pagination in a simple API BLoC example. We use a Notification Listener Widget and Scroll Notifications to accomplish this task. We also use Bloc, Provider and RxDart in this example.

Great video as always we missed your flutter videos even for a little short while as it is always educative. this topic was on my mind the last few days and i am shock you addressed it on clean and clear matter. so i have one request and one question. can we have a tutorial on rxdart (i mean deep one explaining core and advance use cases) as still this one of the challenging topics in dart to use. also none related question if i have an old project made with scooped model and currently after the Provider package came it is much easier to use. what if i want to use Provider in that project? should i add it on top as a parent to the Scoped model "will be there performance issue or any other issue" or i have to convert all project to Provider to use it? (Which i don't want to because it is a lot to do) ... simply put can i use both Scoped model and Provider on same project?

Thank you for the video. Would you show later how to use together? or redux + redux remote devtools.

Hi tensor great tutorial. I'm really struggling with state management particularly using the 'provider' pubspec package. Can you go over an example.

[atehrosius]

Hi Tensor, thanks for the videos. However, data duplicates, when you click on a list item(i created a Details screen for list items), navigate to the details screen, then press the back button on appbar to return to the main screen which has the infinite loop. The first stream of results get shown twice. Do you know what the issue?

Thank you, I was stucked at futurebuilder's trouble with large data. So I paginated my api to response page by page. But when I get last page it goes on and gets 404 error. Error handling is not my solution, I want my app to know it is the last page?? In ur example we cant see because 5000 is too big to try.

Do you share your VSCode config anywhere?

Please can you do an example using a gridview

[erivanbarbosa]

I realized that "onNotification" is called many times for a single scroll gesture. Is that right?

[MlgTheUno]

hey Tensor... the code run well on android emulator ... but i tried it on an iphone simulator it does work... onNotification at the end of the 50 items does not trigger a new call to the api... "bloc.sink.add(scrollInfo)" is never called ...

[hurbes]

can you please share for the same in with firestore please

When i clear the photos at the beginning of the build function and I navigate to another page the data starts from the last one but the past one is erased. I am using a page controller to navigate between pages

[ericel]

Little bug here...Navigating from a page with the infinite scroll, and back to the page, automatically pushes pageNumber to 2 and displays only pageNumber 2 results.
