CollectionView's scroll is not continuous

[echolumaque]

Description

I have a .NET MAUI application that only targets Android. Now it works fine, data is there and loaded. But one thing I noticed is that when I scrolled to the bottom, there is a noticeable delay where it stops my scrolling and then resumes once the data is loaded. I haven't encountered this in Xamarin and it's very frustrating that I have to rely on a third party package just to resolve this buggy scroll.

Also please see the attached videos of debug and release configuration

Debug configuration	Release configuration
debug.mp4	release.mp4

Steps to Reproduce

Create a CollectionView and bind it to an arbitrary amount of items. I would suggest create a layout that would make the CollectionView go beyond its axis. To reproduce it in the attached project, accept the onboarding page, accept the T&C popup and go to inventory tab and start scrolling.
[ EDIT ]: Since I am pushing on this repo from time to time, anyone who would like to check this out should checkout this commit Organisasyon-ng-mga-Malalakas/HealthMate@3e183bd as my reproduction insturction might be invalid due to code changes that is shifting towards real data.

[angelru]

@echolumaque CollecionView in principle I think it has been improved in NET 8.

They suggested using other controls, you can also try:
https://github.com/Keflon/FunctionZero.Maui.Controls#listviewzero

Why doesn't it show an ActivityIndicator in the footer?

Why doesn't it show an ActivityIndicator in the footer?

@angelru I don't know. Is it supposed to show it out of the box?

[ZeBrody]

I only have this behavoiur when adding an ItemsLayout to the CollectionView (wich is required if you want to set spacing)

            <CollectionView.ItemsLayout>
                <LinearItemsLayout Orientation="Vertical" ItemSpacing="10"/>
            </CollectionView.ItemsLayout>

I'm using margin in the ItemTemplate instead of ItemSpacing as a workaround.

By 'behavior' you mean like the video I attached where it pauses for a noticeable time and loads data?

Yes exactly, it scrolls without abrupt interruption without it.
See #13946

[NicoaraBogdan]

Can confirm that using Margin instead of VerticalItemSpacing solves the pauses

[Gloryorb1]

Can confirm that using Margin instead of VerticalItemSpacing solves the pauses

Can confirm this as well.
Edit: Even though the solution by @NicoaraBogdan makes the continuous scrolling possible my swipeview items go invisiable but are still click able.
I also added the a margin to my swipe view and the items still went invisible.

However I removed the margins and used padding instead which seems to allow both the continuous scroll and visible swipe items.

Below is an example:

<CollectionView.ItemsLayout>
    <LinearItemsLayout Orientation="Vertical" /> <!-- Removed ItemSpacing="30" -->
</CollectionView.ItemsLayout>
<CollectionView.ItemTemplate>
    <DataTemplate >
        <SwipeView > <!-- Removed Margin ="0,0,0,30" -->
            <SwipeView.LeftItems>
                <SwipeItem Text="Update" Clicked="MenuUpdate_Clicked" CommandParameter="{Binding ID}"/>
                <SwipeItem Text="View" Clicked="MenuView_Clicked" CommandParameter="{Binding ID}"  />
                <SwipeItem Text="Delete" Clicked="MenuDelete_Clicked" CommandParameter="{Binding ID}"  />
                <SwipeItem Text="+ Ins" Clicked="MenuAddIns_Clicked" CommandParameter="{Binding ID}"  />
            </SwipeView.LeftItems>

            <Grid 
                Padding="20, 0, 0, 30" 
                ColumnSpacing="10"
                RowSpacing="10"
                > <!-- Removed Margin ="0,0,0,30" -->
