grouped_list

Grouped list package for Flutter.

A flutter ListView in which list items can be grouped to sections.

Features

• Sound null safety support!
• Easy creation of chat dialog.
• List Items can be separated in groups.
• For the groups an individual header can be set.
• Almost all fields from ListView.builder available.

Getting Started

Add the package to your pubspec.yaml:

 grouped_list: ^6.0.0

In your dart file, import the library:

import 'package:grouped_list/grouped_list.dart';

Instead of using a ListView create a GroupedListView Widget:

 GroupedListView<dynamic, String>(
   elements: _elements,
   groupBy: (element) => element['group'],
   groupSeparatorBuilder: (String groupByValue) => Text(groupByValue),
   itemBuilder: (context, dynamic element) => Text(element['name']),
   itemComparator: (item1, item2) => item1['name'].compareTo(item2['name']), // optional
   useStickyGroupSeparators: true, // optional
   floatingHeader: true, // optional
   order: GroupedListOrder.ASC, // optional
   footer: Text("Widget at the bottom of list"), // optional
 ),

Parameters:

Also the fields from ListView.builder can be used.

Highlight - SilverGroupedList

Now supporting a grouped list based on a silver list. Just use SilverGroupedListView instead of GroupedListView. An example can be found under example/lib/example_silver. Note that some options of the GroupedListView are currently not available in SilverGroupedListView.

Highlight - Chat Dialog

Easy creation of chat dialogs. Just set the option reverse to true and order to GroupedListOrder.DESC. A full example can be found in the examples. The list will be scrolled to the end in the initial state and therefore scrolling will be against redeaing direction.
