Installation

dependencies:
  flutter_realistic_flipbook: ^0.1.4

flutter pub get

Import

import 'package:flutter_realistic_flipbook/flutter_realistic_flipbook.dart';

Basic Usage

final controller = FlipbookController();

RealisticFlipbook(
  controller: controller,
  pages: pages,
  flipDuration: const Duration(milliseconds: 1200),
);

Page Content Modes

Image Mode

Use image-based pages when content is static.

final pages = <FlipbookPage?>[
  null,
  const FlipbookPage(image: AssetImage('assets/pages/1.jpg')),
  const FlipbookPage(image: AssetImage('assets/pages/2.jpg')),
  const FlipbookPage(image: AssetImage('assets/pages/3.jpg')),
];

Widget Mode

Use widget-based pages when content is dynamic or interactive.

final pages = <FlipbookPage?>[
  null,
  FlipbookPage(
    sizeHint: const Size(1000, 1414),
    widgetBuilder: (context) => Container(
      color: const Color(0xFFFFF8E8),
      padding: const EdgeInsets.all(24),
      child: const Text('Dynamic page'),
    ),
  ),
  FlipbookPage(
    sizeHint: const Size(1000, 1414),
    widgetBuilder: (context) => Container(
      color: const Color(0xFFFFF8E8),
      child: const Center(child: Text('Another page')),
    ),
  ),
];

Gesture Integration

If your page widgets handle their own taps/presses, enable gesture pass-through:

RealisticFlipbook(
  pages: pages,
  allowPageWidgetGestures: true,
  tapToFlip: false,
  clickToZoom: false,
  dragToFlip: true,
)

Navigation Guard

Use onFlipGuard to block a flip before the animation starts:

RealisticFlipbook(
  pages: pages,
  onFlipGuard: (currentPage, targetPage, direction, auto) {
    final inAllowedRange = targetPage >= 10 && targetPage <= 30;
    return inAllowedRange;
  },
)

Core API

RealisticFlipbook

Main widget that renders and animates the book.

Use it to configure:

• pages and controller
• animation and navigation behavior
• single vs double page layout
• zoom and gesture behavior
• visual styling (paper/chrome)

FlipbookPage

Data model for one page.

A page can be defined with either:

• an image, or
• a widgetBuilder

You can also provide optional metadata (headerText, footerText, etc.).

FlipbookController

Imperative controller for navigation and zoom.

It exposes:

• state (page, numPages, canFlipLeft, canFlipRight, ...)
• actions (flipLeft, flipRight, zoomIn, zoomOut, goToPage)
