Probably should explicitly provide duration and curve.

I tried to use this package but i do not understand how padding works. In example with horizontal padding there is only padding.left property used. If i remove padding property - snap list item have 0 lef padding, but still it is centered vertical, so i assume it has vertical padding. How can i remoe all paddins or set my own?

This could be circumvented by either using the snaplist or using other widgets, but if it is easy to accomplish it would be great to pass a parameter during build that can disable the ability to scroll for scenarios where the items in the snaplist are smaller than the space allotted and are more of a static list than a scroll widget. Is that something you guys would consider implementing?

Including the library and perfomre the "Showcase" example does not work. Nothing happens. The examples also didn't work. You have to copy the example code and create new files then import them. Anyways, how to get to work the "showcase" example?

In my code, the data.center is not showing the correct indexes, sometimes it's even showing the same center index for different pages.

SnapList(
    padding: EdgeInsets.only(
        left: (screenSize.width - cardSize.width) / 2),
    sizeProvider: (index, data) => cardSize,
    separatorProvider: (index, data) => Size(10.0, 10.0),
    positionUpdate: (int index) {
        print("Current Index: ${index}/${pageCards.length}");
        if (index == pageCards.length - 1) {
            //                          loadMore();
        }
    },
    builder: (context, index, data) {
        print("###########################");
        print("Index: ${index}");
        print("Center: ${data.center}");
        print("Next: ${data.next}");
        print("Progress: ${data.progress}");
        return ProfileCard(pageCards[index], image1, offset,
            () {}, dismissCard);
    },
    count: pageCards.length,
)

When changing a parameter on the Snaplist itself the app has to be restarted to apply changes.

It would be great if the "next" property was documented on the main readme page.

@ariedov Hi,

how did you get the pop effect of the card in the vertical scroll list. I am referring to the screenshot you have with list of diff movies.

I am able to get the scroll but can't figure out the pop of effect of the card when it comes to the center.

Thanks

Hi,
Thanks for this great plugin. But I am facing one issue in this.

Once you bind the SnapList on page it is not updating when data changed.
I tried this with streambuilder, futurebuilder & async data list.

In FutureBuilder & StreamBuilder, its loading the data & list count is changed but SnapList items are not changing. Also it keep firing positionUpdate callback after list refresh.

In async data list, one the page load I am getting the data from server & when I call setState its showing first item. No gesture is working & positionUpdate callback fires with index as "-1".

I am trying now with this project's branch. Will let you know if I found something.

I want to use it in my flutter project. I know how to import it, but the main question is that if I have widget which has an image in it, I want that to be shown in the view, but don't know how to implement it. I just want the view same the horizontal view of the example. If you could show me the code of your example, I will get it somehow. But right now I'm clueless on how to use it in my project. Any help would be appreciated.

Hello Sir
I have been trying to use your package for a while now and I am not able to Re-size your widget dynamically
(actually i can, but the current snapped object goes off the view) and I am not able to maintain the current object in view(it goes off left).
HERE is a link to a small video showcasing the issue :
and here is the code of the SliverPersistentHeaderDelegate I attempted to do :
CodePile code.
I also mailed you on your email ID
Ps: SizeConfig is nothing more than just
((MeDiaQuery.of(context).size.[widthORheight])/100) = percentage of the screen in blocs

Probable solution is to forcefully wrap every child to a fixed size Container or SizedBox.

In the above GIF, you have dismissed the movie Predator.

How was that possible? I have been trying to do it for hours now and fail

Update:
I can't make it so the right card moves to the left to take place of the removed card

Migration to null saftey

I try to using setPosition. The functional working well except it doesn't have animation. It just jumps directly to the position. I try to set snipDuration but not effect. Can anyone help me?. Thanks

First, thank you for this awesome plugin. Looking forward to using it.

Because there is no controller accepted as a parameter to the SnapList constructor, there is no way to facilitate starting at an initial index, or scrolling to a particular index. It would be wonderful if such functionality could be added.

When changing the locale to RTL languages, the vertical scroll remains its direction.
