Issue / Feature - Feature
Platform (android, iOS or both) - Android preferably

Bookmark feature is not available in folioreader, can this be achieved here? One way I was thinking to store the last location on some button press, is this possible, any insight would be helpful.

                            print(
                                'LOCATOR: ${EpubLocator.fromJson(jsonDecode(locator))}');
                            // convert locator from string to json and save to your database to be retrieved later

how to read book from "network URL"?

Hi @JideGuru
The page viewer shows the remaining pages for the current chapter of the epub, and not the complete epub itself and it doesn't work in Horizontal scroll at all. In horizontal scroll, it sticks at 1 page left.
I have tested these on android only.

Platform - Both

how can i remove Copy, Share , Define functionalities ?

for example : When i select text only appears colors highlight

When i am running app on android (realme device) i got error such as below:
E/AndroidRuntime(22852): java.lang.RuntimeException: Font asset not found /system/fonts/MyanmarZg_exp.ttf
How to fix that?

Issue / Feature - Opening Assets and Network Epubs
Platform (android, iOS or both) -
Crash / Error - The app runs perfectly on the emulator but the same apk crashes when installed on a real device.

Steps to reproduce / Describe in detail - I just installed the plugin and wrote the code as directed.

Can you help me in a direction that can help me solve this issue? Any help will be appreciated.

hello,
would you mind trying a sdk change to Readium, a more stable & well maintained epub sdk for android?
folio is not fixing some big issues, like randering a big TOC, and opening big epub files.
thanks,
Tayeb.

1.downloaded the codes(comment everything thats not related to "load from assets") note: had some issues and started to fix them one by one. 2.put assets in lib folder 3.write lib/assets/book.epub in both pubspec.yaml and in code (it doesnt even open the file otherwise)

Hi @JideGuru,
I wanted to disable the screenshot inside FolioReader but both flutter_windowmanager as well as adding code to the native side don't seem to work. They disable screenshot inside the app but don't have any effect on folioReader. Is there any way to include this functionality?

Thanks lot for this amazing package.
