如何在Flutter中显示epub文件的封面

dependencies:
  epub: ^3.0.0

import 'package:epub/epub.dart';

Future<EpubBook> loadEpubBook(String epubFilePath) async {
  final bytes = await File(epubFilePath).readAsBytes();
  final epubBook = await EpubReader.readBook(bytes);
  return epubBook;
}

String getCoverImagePath(EpubBook epubBook) {
  final coverImage = epubBook.CoverImage;
  if (coverImage != null) {
    return coverImage.Content.Images.first.ImagePath;
  }
  return null;
}

import 'package:flutter/material.dart';

class EpubCoverPage extends StatelessWidget {
  final String coverImagePath;

  EpubCoverPage(this.coverImagePath);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: coverImagePath != null
            ? Image.file(File(coverImagePath))
            : Text('No cover image available'),
      ),
    );
  }
}

Navigator.push(
  context,
  MaterialPageRoute(
    builder: (context) => EpubCoverPage(coverImagePath),
  ),
);
