Showcase #

Getting Started #

In your flutter project add the dependency:

flutter pub add epub_view

Usage example: #

import 'dart:typed_data';

import 'package:flutter/material.dart';
import 'package:flutter_epub/flutter_epub.dart';

late EpubController _epubController;

@override
void initState() {
  super.initState();
  _epubController = EpubController(
    // Load document
    document: EpubDocument.openAsset('assets/book.epub'),
    // Set start point
    epubCfi: 'epubcfi(/6/6[chapter-2]!/4/2/1612)',
  );
}

@override
Widget build(BuildContext context) => Scaffold(
  appBar: AppBar(
    // Show actual chapter name
    title: EpubViewActualChapter(
      controller: _epubController,
      builder: (chapterValue) => Text(
        'Chapter: ' + (chapterValue?.chapter?.Title?.replaceAll('\n', '').trim() ?? ''),
        textAlign: TextAlign.start,
      )
    ),
  ),
  // Show table of contents
  drawer: Drawer(
    child: EpubViewTableOfContents(
      controller: _epubController,
    ),
  ),
  // Show epub document
  body: EpubView(
    controller: _epubController,
  ),
);

How start from last view position? #

This method allows you to keep the exact reading position even inside the chapter:

_epubController = EpubController(
  // initialize with epub cfi string for open book from last position
  epubCfi: 'epubcfi(/6/6[chapter-2]!/4/2/1612)',
);

// Attach controller
EpubView(
  controller: _epubController,
);

// Get epub cfi string
// for example output - epubcfi(/6/6[chapter-2]!/4/2/1612)
final cfi = _epubController.generateEpubCfi();

// or usage controller for navigate
_epubController.gotoEpubCfi('epubcfi(/6/6[chapter-2]!/4/2/1612)');

Api #

Open document #

Local document open:

EpubDocument.openAsset('assets/sample.pdf')

EpubDocument.openData(FutureOr<Uint8List> data)

// Not supports on Web
EpubDocument.openFile('path/to/file/on/device')

Network document open:

Install [network_file] package (supports all platforms):

flutter pub add internet_file

And use it

import 'package:internet_file/internet_file.dart';

// The cors policy is required on the server. 
// You can raise your cors proxy.
EpubDocument.openData(InternetFile.get('https://link.to/book.epub'))

Control document #

// Get epub cfi string of actual view insets
// for example output - epubcfi(/6/6[chapter-2]!/4/2/1612)
final cfi = _epubController.generateEpubCfi();

// Navigate to paragraph in document
_epubController.gotoEpubCfi('epubcfi(/6/6[chapter-2]!/4/2/1612)');

  controller: epubController,
