sticky_header_list

Sticky Header list for Flutter.

Usage

You need to wrap your widgets with StickyListRow. Use HeaderRow for headers that sticks and RegularRow for regular rows that scroll normally.

Height is optional, but if you include it, it will avoid usage of GlobalKeys to determine height:

new StickyRow(child: yourWidget, height: 20.0)

Usage is similar to ListView. You can either supply list:

new StickyList(
      children: <StickyListRow>[
        new HeaderRow(child: yourWidget),
        new RegularRow(child: yourWidget),
        new RegularRow(child: yourWidget),
        new HeaderRow(child: yourWidget),
        new RegularRow(child: yourWidget),
        /...
      ],
    );
    

Or you can use builder:

 new StickyList.builder(
      builder: (BuildContext context, int index) {
        if (something)
          return new HeaderRow(yourWidget)
        else
          return new RegularRow(yourWidget)
      },
      itemCount: 20,
    );
