CustomListView breaks when switching from 0.1.5 to 0.2.6+2 in combination without adapter

Thank you.

I am using the package to display data from a custom data repository (an internal service thatloads data from rest api) and need the pull to refresh functionality to call the refresh of the data repository.

I have not found a better package for this usage.

Thank you. By the way, this package is using RefreshIndicator widget from flutter SDK. You can add it to any flutter list widget.

RefreshIndicator(
  onRefresh: () => Future.delayed(Duration(seconds: 2)),
  child: ListView(
    children: [],
  ),
),

I would suggest using it if you don't need additional stuff. Don't get me wrong 😅 That's just an advice to reduce dependencies on 3rd party code (like this package).

Some more detail regarding the error:

The exception happens in the custom_list_view.dart file in the SliverChildDelegate type function _buildDelegate(). To be more precise in line 299 when executing return widget.itemBuilder(context, index, items[index]); and the items list is empty instead of carrying all the loaded items.

Also, in the earlier version of the code there is a check if widget.adapter is null so it won't return the empty items list (line 167: https://github.com/TheMisir/flutter-listutils/blob/18a63bf9507d2d15384f0b061bb36bbda7afdcfe/lib/src/custom_list_view.dart). Why is this check not in use anymore?

@themisir Thanks for merging the fix. Is it possible to publish this newest version to pub.dev so we can use it directly?

[themisir]

Thanks for your contribution. I've just published to pub.dev.

I want to ask a question about package usage.

What feature are you using this package for?

What is the reason for using this package?

@themisir Thank you very much. I did not know RefreshIndicator and that it is quite simple to integrate it. Will try it out while refactoring!

However, I still like your package since it offers some nice options ;-)
