First of all, thanks for the project!

How can I reset the list (initialData)? I do have search input + other filters that I need to apply to the search.

Thanks again.

Hi. Can anyone help me with pagefetch logic, below is my code for the current pagefetch logic. Currently the page number is set as static but i want it to return an empty list on the last page of my Map's length.

PageFetch: Future<List<User>> pageFetch(int offset) async { print(offset); print(moreRestaurantsMap['data'].length); page = (offset / 4).round(); final Faker faker = Faker(); final List<User> nextUsersList = List.generate( 5, (int index) => User( faker.person.name() + ' - $page$index', faker.internet.email(), ), ); await Future<List<User>>.delayed(Duration(seconds: 1)); return page == 24 ? [] : nextUsersList; }

Below is the error I receive

Total number of restaurants at the backend is 104 but it should not matter as pagefetch should be dynamic and should be able to handle the length properly

I can't set page variable to 0 and cant print 'refreshed' to console when i pull.Beause of that every time i'm getting next page when im refresh.But i want to refresh all from first page.Am i doing something wrong ?

fetch and refresh methods

 Future<List<Entry>> fetchPage(int offset) async {
    page++;
    String url = craw.BASE + currentHref + pageText();
    print(url);
    EntryPageModel model = await craw.crawEntryPage(url);
    pageModel = model;

    return pageModel.entries;
  }

  Future<List<Entry>> refresh(int offset) async {
    print('refreshed');
    page = 0;
    return fetchPage(offset);
  }

This is my pagination_view

PaginationView<Entry>(
                    key: paginationKey,
                    shrinkWrap: true,
                    separatorBuilder: (context, index) {
                      if (index % 9 == 0 && index != 0)
                        return TextDivider(
                            text: '${(index / 10).round()}. sayfa sonu');
                      else
                        return Divider(color: Colors.white30, thickness: 1);
                    },
                    preloadedItems: [],
                    paginationViewType: PaginationViewType.listView,
                    pageFetch: this.fetchPage,
                    pageRefresh: this.refresh,
                    pullToRefresh: true,
                    onError: (dynamic error) => Center(
                      child: Text('Some error occured'),
                    ),
                    onEmpty: Center(
                      child: Text('Sorry! This is empty'),
                    ),
                    bottomLoader: Center(
                      child: CircularProgressIndicator(),
                    ),
                    itemBuilder: (context, entry, index) {
                      return AnimationConfiguration.staggeredList(
                        position: index,
                        child: SlideAnimation(
                          horizontalOffset: 25,
                          duration: Duration(milliseconds: 100),
                          child: EntryWidget(
                            entry: entry,
                          ),
                        ),
                      );
                    },
                  )

I made a refresh feature. You can refresh the page by referring to the PaginationViewState using a global key and can call key.currentState.refresh().

Hi. When i try to scroll down, the pagefetch method gets called multiple times and the backend gets throttled. Is there any way to hit the method only once?

There is any way to refresh a PaginatedView programmatically ?

I'm have the pagination_view widget and a form on the same page. When the form is submitted, I need to refetch, to update the list I'm showing with PaginatedView

Thanks

I have the main UI code which starts from header and the main parent is a gesture Detector widget. After updating to the latest null safety version, I am getting the below error:

The following assertion was thrown building NotificationListener<ScrollNotification>: A RenderShrinkWrappingViewport expected a child of type RenderSliver but received a child of type RenderRepaintBoundary. RenderObjects expect specific types of children because they coordinate with their children during layout and paint. For example, a RenderSliver cannot be the child of a RenderBox because a RenderSliver does not understand the RenderBox layout protocol. The RenderShrinkWrappingViewport that expected a RenderSliver child was created by: ShrinkWrappingViewport ← IgnorePointer-[GlobalKey#58bb2] ← Semantics ← Listener ← _GestureSemantics ← RawGestureDetector-[LabeledGlobalKey<RawGestureDetectorState>#b659b] ← Listener ← _ScrollableScope ← _ScrollSemantics-[GlobalKey#4bfcf] ← RepaintBoundary ← CustomPaint ← RepaintBoundary ← ⋯ The RenderRepaintBoundary that did not match the expected child type was created by: RepaintBoundary ← NotificationListener<ScrollNotification> ← GlowingOverscrollIndicator ← Scrollable ← PrimaryScrollController ← SingleChildScrollView ← ShrinkWrappingViewport ← IgnorePointer-[GlobalKey#58bb2] ← Semantics ← Listener ← _GestureSemantics ← RawGestureDetector-[LabeledGlobalKey<RawGestureDetectorState>#b659b] ← ⋯

1. make make 'AlwaysScrollableScrollPhysics()' by default. so it can pull to refresh although the list / child view is not scrollable
2. fix onEmpty and on error that can not be pulled to refresh

Hello, am having a frustrating problem with Pagination View, am retrieving list of movies from my API and displaying them in my pagination view, the data is retrieved in a ChangNotifier class and the pagination view widget is wrapped in a consumer, but the pagination view doesn't load the new data when they arrive, unless i pull down refresh.

this is a video demo to better describe my problem https://streamable.com/ca8k8g

I apologize if am making a rookie mistake, am learning flutter and i may have missed a pretty obvious step to setting up this function.

Thanks for the awesome widget; but when I try it inside the SliverToBoxAdapter, it automatically execute pageFetch function until get all data; the same when put it in another ListView, shrinkWrap is set true.

Hello, I was trying to implement this package and I noticed that when I fetch data from an API and the number of data returned is not enough to cover the whole view or enough to have it scroll, it causes the bottomLoader to maintain its visibility. Can you help me, please?

Here is a screenshot

Hi! I faced a situation when it's necessary to have several sliver widgets in header or footer and I didn't find other solution except update this component. Please review it.

PS Very thanks for this component! It saved a lot of mine time

Change log for version 2.0.0 details breaking issue where header and footer only accept Sliver Widget. Example code uses Text() Widget. As a result the example code does not run and causes dart framework to crash. Please correct example code.

I only found this b/c another user in an unrelated Stack Overflow post mentioned not using Sliver in a custom scroll view caused a similar error. Then I stumbled across the change log and made the connection. Other devs may not be so lucky.

Hi there!

I updated some dependencies. I hope you can create a new release soon since te latest available release on pub.dev required flutter_bloc: 7.*.*

Fixes #58

Hi there!

I have the issue the elements can occur multiple times in the PaginationView. This is the case if new elements are added to the top of my list in the backend. More detailed steps to explain my problem:

1. If I open my PaginationeView for the first time, I see the first 15 items like expected (15 is always my limit for API requests). The request is send to my backend with offset=0 and limit = 15.
2. Waiting some time. Meanwhile, a new item is added in my backend at the top of the list.
3. Now scrolling down will trigger a second API request with offset=15 and limit=15. PaginationView automatically append both results to a list of 30 items. But in the described scenario an item it duplicated (position 15, last of the first request and position 16, first of second request)

There might be multiple solutions for this specific problem. I'm not sure what is best practice here. From my point of view, I'd like to have a optional parameter expiration of type Duration which forces the PaginationView to reload the whole list even if it has already loaded many items and the user scrolls down.

What do you think about this?
