Hey I'm running the code in Intelli J with Flutter Plugin. Everything works great, except I can't open any of the books. Here's the issue that I get. What do you think could be the issue?

I want to update a book state from a page, but I got this error.

flutter: ══╡ EXCEPTION CAUGHT BY FOUNDATION LIBRARY ╞════════════════════════════════════════════════════════
        flutter: The following assertion was thrown while dispatching notifications for Book:
        flutter: setState() or markNeedsBuild() called during build.

class BookCard extends StatelessWidget {
  final String img, filename, url;
  Book book;
  BookCard(
      {Key key,
      @required this.img,
      @required this.url,
      this.filename,
      this.book})
      : super(key: key);

@override
  Widget build(BuildContext context) {
    final BookProvider = Provider.of<BookProvider>(context);
    BookProvider.setEntry(book);
    return Container(
    child:  BookProvider.downloaded
                    ? GestureDetector(
                        onTap: () => {
                                     //Read the book without trying to download it*
                                      }
                    : GestureDetector(
                        onTap: () => {
                                       //Download it*
                                      }

And in the Provider Class

class BookProvider extends ChangeNotifier {
  final database = DownloadsDB.instance;
  bool downloaded = false;
  Book book;

void setEntry(value) {
    book = value;
    notifyListeners();
  }
...
}

Target of URI doesn't exist: 'package:flutter/material.dart'. Try creating the file referenced by the URI, or Try using a URI for a file that does exist.

E/flutter (21181): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: FileSystemException: Creation failed, path = '/storage/emulated/0/Flutter Ebook App' (OS Error: Permission denied, errno = 13)

After downloading any book, clicking on the read now button to read the epub causes the app to instantly crash, it works fine in debug mode but crashes in release mode.

Local directory (In android device, so download is not working) not created if we used targetSdkVersion 29 and 30 on build.gradle file. We need set minimum 29 and 30 for playstore console.

An overflow error caused due to harcoding size of the book-section-container .

Pull request addressing this issue : https://github.com/JideGuru/FlutterEbookApp/pull/41

The Container size was hardcoded as 200 therfore it would overflow in many devices as shown below.

Image demonstrating the fix :

• Simply removing the hardcoded size, the container would automatically adjust itself according to its children's size, thus fixing the overflow issue .

I think there is a problem with the description_text.dart component where for description with less than 300 texts it still shows ... at the end without the show more.

Hello I really i am lost here, i downloaded the app source files, added them to Flutter, dart is enabled, flutter is fine, but when i just try to run it on my android for testing with flutter i got this error :

i tested with Android 9 real device. Forexample if we run with release mode then if you set targetSdkVersion is 25 it is working but if you install and uninstall app or manually deleting the data then downloads section shows only 1 book.

In targetSdkVersion 28 and 29 it is not working. I also upgraded the "cached_network_image to 2.5.1" because of the error. But i tested many times reading book and the download page not working. Reading book shows blank page after reloading and download page shows only the latest book.

On terminal it print "Unknown chunk type '200' " and also "Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.WindowInsetsAnimation$Callback" on path:"

if we run with debug mode then extra error invalid image data but same things not working also in debug mode.

hi buddy thanks for such a good library. I have to release a flutter app which can read epub books on android and web. I want to know if you have any plan for new update on this library for supporting flutter web application also or not? I could not find any flutter epub reader library for supporting web applications.
