zhixinpeng/anchor_tabs

This project is a way to implement a anchor tabs panel like the one of the rhymit.

The idea is that sometimes you have a big list where you can scroll, but you still want buttons to help the user to navigate to different scroll positions, and also want that the selected button keeps updated as you scroll

Anchor tabs provide a great user experience as it let the user do what they like most: keep scrolling. While providing a way to navigate to specific positions of that scroll.

I made this video explaining how to use this package: https://www.youtube.com/watch?v=CPql7o1utiM

Features

Tab button scroll to the block Scrolling will update the tab button selected

Getting started

Add the dependency to your pubspec.yaml:

anchor_tabs: ^0.0.5

Usage

class SimpleExample extends StatelessWidget {
  const SimpleExample({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    List<String> tabsText = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

    List<Widget> tabs = [];
    List<Widget> body = [];

    for (var element in tabsText) {
      // Create a tab item
      tabs.add(Text(element));

      // Create a target item
      body.add(ListView.builder(
          scrollDirection: Axis.vertical,
          shrinkWrap: true,
          controller: ScrollController(),
          itemCount: 40,
          itemBuilder: (BuildContext ctxt, int i) {
            return Text('$element  $i',
                style: Theme.of(ctxt).textTheme.headline6);
          }));
    }

    return Container(
      margin: const EdgeInsets.all(10),
      child: Column(
        children: [
          const Text('Simple example of anchor tabs'),
          Expanded(child: AnchorTabPanel(tabs: tabs, body: body)),
        ],
      ),
