EpubViewer.setConfig(
  themeColor: Theme.of(context).primaryColor,
  identifier: "iosBook",
  scrollDirection: EpubScrollDirection.VERTICAL,
  allowSharing: true,
  enableTts: true,
)

/**
* @bookPath
* @lastLocation (optional and only android)
*/
EpubViewer.open(
  'bookPath',
  lastLocation: EpubLocator.fromJson({
    "bookId": "2239",
    "href": "/OEBPS/ch06.xhtml",
    "created": 1539934158390,
    "locations": {
       "cfi": "epubcfi(/0!/4/4[simple_book]/2/2/6)"
    }
  }), // first page will open up if the value is null
);

// Get locator which you can save in your database
EpubViewer.locatorStream.listen((locator) {
   print('LOCATOR: ${EpubLocator.fromJson(jsonDecode(locator))}');
   // convert locator from string to json and save to your database to be retrieved later
});

You can also load epub from your assets using EpubViewer.openAsset()

await EpubViewer.openAsset(
  'assets/3.epub',
  lastLocation: EpubLocator.fromJson({
      "bookId": "2239",
      "href": "/OEBPS/ch06.xhtml",
      "created": 1539934158390,
      "locations": {
         "cfi": "epubcfi(/0!/4/4[simple_book]/2/2/6)"
      }
  }), // first page will open up if the value is null
 );

// Get locator which you can save in your database
EpubViewer.locatorStream.listen((locator) {
   print('LOCATOR: ${EpubLocator.fromJson(jsonDecode(locator))}');
   // convert locator from string to json and save to your database to be retrieved later
});
