In your flutter project add the dependency:
dependencies:
epub_view: any
Usage example: #
import 'dart:typed_data';
import 'package:flutter/material.dart';
import 'package:flutter_epub/flutter_epub.dart';
import 'package:flutter/services.dart' show rootBundle;
Future<Uint8List> _loadFromAssets(String assetName) async {
final bytes = await rootBundle.load(assetName);
return bytes.buffer.asUint8List();
}
EpubController _epubController;
@override
void initState() {
_epubController = EpubController(
// Load document
document: EpubReader.readBook(_loadFromAssets('assets/book.epub')),
// Set start point
epubCfi: 'epubcfi(/6/6[chapter-2]!/4/2/1612)',
);
super.initState();
}
@override
Widget build(BuildContext context) => Scaffold(
appBar: AppBar(
// Show actual chapter name
title: EpubActualChapter(
controller: _epubController,
builder: (chapterValue) => Text(
'Chapter ${chapterValue.chapter.Title ?? ''}',
textAlign: TextAlign.start,
),
),
),
// Show table of contents
drawer: Drawer(
child: EpubReaderTableOfContents(
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)');
