    sdk: flutter

Then, run flutter pub get to install the package.

Usage

Here is a step-by-step guide to using the e_book_reader package in your Flutter application.

import 'package:e_book_reader/e_book_reader.dart';
import 'package:e_book_reader/reader_controller.dart';
import 'package:e_book_reader/reader_pull_to_refresh.dart';

Basic Setup

Create a ReaderController and configure it in your widget:

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  final ReaderController _readerController = ReaderController();

  @override
  void initState() {
    _readerController.load(longText);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text("E-Book Reader"),
      ),
      body: ReaderContent(
        controller: _readerController,
      ),
    );
  }
}

Add Scroll Listener

@override
void initState() {
  _readerController.load(longText);
  _readerController.addScrollListener(() {
    print("Scroll Position: ${_readerController.scrollPosition}");
  });
  super.initState();
}

Customizing the Reader

You can customize various aspects of the reader using the ReaderController:

_readerController.setFontSize(18);
_readerController.setFontWeight(FontWeight.bold);
_readerController.setFontStyle(FontStyle.italic);
_readerController.setTextAlign(TextAlign.justify);
_readerController.setColor(Colors.black, Colors.white);
_readerController.setAxis(Axis.horizontal);
_readerController.setLineHeight(1.8);
_readerController.setPadding(EdgeInsets.all(16));
_readerController.setFontFamily("serif");

Pull-to-Refresh

To enable pull-to-refresh functionality, wrap the ReaderContent widget with ReaderPullToRefresh:

ReaderPullToRefresh(
  onRefreshTop: () async {
    // Handle top refresh
  },
  onRefreshBottom: () async {
    // Handle bottom refresh
  },
  child: ReaderContent(
    controller: _readerController,
  ),
)
