Flutter Sticky Headers: Enhance Your Scrollable Content

Flutter Sticky Headers is a powerful package that enables you to add sticky headers to your scrollable content. These headers remain fixed at the top of the container, providing users with a convenient way to navigate and identify different sections.

Usage

To use Flutter Sticky Headers, simply wrap your header and content inside a StickyHeader widget. You can use it within any scrollable widget, such as ListView, GridView, CustomScrollView, or SingleChildScrollView.

class Example extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemBuilder: (context, index) {
        return StickyHeader(
          header: Container(
            height: 50.0,
            color: Colors.blueGrey[700],
            padding: EdgeInsets.symmetric(horizontal: 16.0),
            alignment: Alignment.centerLeft,
            child: Text(
              'Header #$index',
              style: const TextStyle(color: Colors.white),
            ),
          ),
          content: Container(
            child: Image.network(
              imageForIndex(index),
              fit: BoxFit.cover,
              width: double.infinity,
              height: 200.0,
            ),
          ),
        );
      },
    );
  }
}

Examples

Example 1: Headers and Content

In this example, you can clearly see the sticky headers and their corresponding content as you scroll down.

import 'package:sticky_headers/sticky_headers.dart';

// ...

class Example extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemBuilder: (context, index) {
        return StickyHeader(
          header: Text('Header #$index'),
          content: Text('Content #$index'),
        );
      },
    );
  }
}

Example 2: Animated Headers with Content

This example showcases animated headers that smoothly transition as you scroll.

import 'package:sticky_headers/sticky_headers.dart';

// ...

class Example extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemBuilder: (context, index) {
        return StickyHeader(
          header: AnimatedContainer(
            duration: Duration(milliseconds: 200),
            height: 50.0,
            color: Colors.blueGrey[700 + (index * 100) % 200],
            padding: EdgeInsets.symmetric(horizontal: 16.0),
            alignment: Alignment.centerLeft,
            child: Text(
              'Header #$index',
              style: const TextStyle(color: Colors.white),
            ),
          ),
          content: Text('Content #$index'),
        );
      },
    );
  }
}

Example 3: Headers Overlapping the Content

You can also choose to have the headers overlap the content, providing a subtle but effective visual cue.

import 'package:sticky_headers/sticky_headers.dart';

// ...

class Example extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemBuilder: (context, index) {
        return StickyHeader(
          overlapsContent: true,
          header: Text('Header #$index'),
          content: Text('Content #$index'),
        );
      },
    );
  }
}

Conclusion

Flutter Sticky Headers is a versatile and powerful tool that can enhance the user experience of your scrolling content. With its ability to create sticky headers that seamlessly integrate with your content, you can provide users with a more organized and intuitive navigation system.
