flutter_sticky_headers

flutter_sticky_headers copied to clipboard

When SliverAppBar inside CustomScrollView is set to be shown only on scroll up (floating: true), header stays on its place e.g. goes below appbar. How to make it shift down on appbar showing?

P.S.: I don't want to use this flutter_sticky_header, since it can't work with ListView builder.

You can try sticky_and_expandable_list, just use as one SliverList.

It works, but for some reason sticky headers now go below statusbar in collapsed mode (code from example_sliver.dart).

The hidden height is statusbar height, I have updated the example project. Just wrap Scaffold with SafeArea.

@tp7309 Great, bug is fixed now! Thanks!

My only question remaining is -- how to make headers and content share the same index in list? In my case of usage each section contains only one header and one child, and I want them to share the same index.

Echo itemBuilder return the section model and item model, you can get section/header index from section model, example:

            SliverExpandableList(
              builder: SliverExpandableChildDelegate<String, Section>(
                  sectionList: sectionList,
                  headerBuilder: _buildHeader,
                  itemBuilder: (context, section, item, index) {
                    //get sectionIndex by sectionList
                    int sectionIndex = sectionList.indexOf(section);
                    return ListTile(
                      leading: CircleAvatar(
                        child: Text("$sectionIndex"),
                      ),
                      title: Text(item),
                    );
                  }),
            )

@tp7309 Works great now, thanks a lot! Thanks for your help with my issue.

Your package is a great alternative for the two existing 'sticky-headers' packages. Some ideas for improving:

1. Built-in collapse animation for setSectionExpanded() method;
2. Ability to integrate with LiveSliverList from auto_animated package;
3. Make Section() constructor not only String-oriented, but to accept widgets as well.

@emvaized Good idea! Animation support coming soon, you can star repo for receive lastest version update. Some explanations about Option 3.

@tp7309 Cool, thanks for your work! I'll try it. I also created a few new issues for further improvement of your package :)

However, I will leave this issue open, since the problem still exists in discussed package.

@slightfoot Is this project abandoned?
