Overall, Flutter sticky headers are a valuable tool for enhancing both the usability and visual appeal of your app.

To begin, create a new Flutter project or navigate to your existing root directory. The first step is to update your yaml file with the necessary dependencies. Once you’ve updated the yaml file, run a package get command to import the new package into your Flutter project.

dependencies:
  flutter_sticky_header: ^version

Once the dependencies have been successfully included, make sure to import the library package into your project using the following line of code:

import 'package:flutter_sticky_header/flutter_sticky_header.dart';

Alright! You’ve successfully added the Flutter Sticky Header package and are halfway there. Next, we’ll explore different Flutter Sticky Header library methods.

Using SliverStickyHeader

Flutter’s SliverStickyHeader widget makes adding sticky headers to your app a breeze. Simply wrap your desired header widget along with a scrollable content widget (like SliverList or SliverGrid) inside a CustomScrollView. This powerful combination ensures your header stays fixed at the top while users scroll through the content below, offering them constant access to navigation or other important information.

A basic implementation would look like this:

SliverStickyHeader(
  header: Container(
    height: 60.0,
    color: Colors.lightBlue,
    padding: EdgeInsets.symmetric(horizontal: 16.0),
    alignment: Alignment.centerLeft,
    child: Text(
      'Header #0',
      style: const TextStyle(color: Colors.white),
    ),
  ),
  sliver: SliverList(
    delegate: SliverChildBuilderDelegate(
      (context, i) => ListTile(
            leading: CircleAvatar(
              child: Text('0'),
            ),
            title: Text('List tile #$i'),
          ),
      childCount: 4,
    ),
  ),
);

In this code block, we’ve designed a Container for the header and defined the sticky header widget. The Alignment.centerLeft part aligns with the header’s text.

Users will appreciate the ability to effortlessly navigate through content while keeping essential information readily available. This guide has equipped you with the knowledge to implement sticky headers effectively. Remember to prioritize user experience, explore different packages, and customize header behavior to seamlessly integrate with your app’s design. With sticky headers in your arsenal, you can craft intuitive navigation that keeps users engaged and coming back for more.
