FlexiPageView

FlexiPageView is a drop-in replacement for Flutter's PageView widget. It provides the same API as PageView while dynamically adjusting its height (cross-axis dimension) to match the height of the currently visible page. This makes it ideal for scenarios where pages have varying heights.

Web Demo is available here

Features

• Dynamic Height Adjustment: The height of FlexiPageView smoothly transitions to match the height of the currently visible page.
• Drop-in Replacement: Fully compatible with the PageView API, making it easy to integrate into existing projects.
• Customizable: Supports all standard PageView properties, such as controller, scrollDirection, and physics.

Installation

Add the following dependency to your pubspec.yaml:

dependencies:
  flexi_page_view: <latest_version>

Run flutter pub get to fetch the package.

Usage

Replace your PageView widget with FlexiPageView. The API remains the same, but now the height of the widget will dynamically adjust based on the height of the current page.

Example

import 'package:flexi_page_view/flexi_page_view.dart';

class ExamplePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: FlexiPageView(
        children: [
          Container(
            height: 100,
            color: Colors.red,
            child: Center(child: Text('Page 1')),
          ),
          Container(
            height: 200,
            color: Colors.green,
            child: Center(child: Text('Page 2')),
          ),
          Container(
            height: 150,
            color: Colors.blue,
            child: Center(child: Text('Page 3')),
          ),
        ],
      ),
    );
  }
}

Key Properties

FlexiPageView supports all properties of PageView, including:

• controller: Controls the page view's scrolling behavior.
• scrollDirection: Specifies the axis along which the pages scroll (Axis.horizontal or Axis.vertical).
• physics: Defines the scroll physics for the page view.
• children: A list of widgets representing the pages.

How It Works

FlexiPageView calculates the height of the currently visible page and smoothly animates the widget's height during page transitions. This ensures a seamless user experience when navigating between pages with different heights.

Compatibility

FlexiPageView is compatible with all Flutter versions that support PageView. It can be used in any project where dynamic height adjustment is required.
