MasterStudy LMS Mobile App – Key questions!

Does the user have the capability to pay for the course, downloadable products and membership using the app?

Does the user have the option to pay for the course, product and membership through the app?

We are using the shop page for downloadable products – meaning, the user should be able to buy the downloadable products using the app.

Please confirm if the above can be achieved with your app without any form of customization.

Is this requires some form of customization, how does it works? What needs to be customized – the exact components that need customization?

Thank you and kind regards,

Is there any video security like download restriction, screenshot restriction, recording restriction, share restriction by user/student ?

Pre-purchase question 1. This requires the wordpress theme or its a stand alone? 2. do you offer customization work? 3. Is there a offline payment option?

There are still error by compile APK in Gradle Android mode

Error: Cannot run with sound null safety, because the following dependencies don’t support null safety:

- package:html_unescape
- package:flutter_rating_bar
- package:share
- package:transparent_image
- package:shimmer
- package:equatable
- package:package_info

Thanks for Update the App. But there is still a Bug with Number of lessons shows in Category. Actually in Category View, Favorites and Search Tab you can see only 10 Courses!!!! The rest will not appear. Please Fix it to show all Courses in Category View, Search Tab and Favorites Tab.

And add this to text_lesson_screen.dart to get Nav working for text lessons

int.tryParse(state.lessonResponse.next_lesson)! int.tryParse(state.lessonResponse.prev_lesson)!

Please update your changelog

is there any way to change from LTR to RTL ??

Today 21.11.2022 new version is out. Can you provide the Flutter settings or Version? I have tried to compile the main.dart but the output comes with Errors. For now the new version is useless.

Can you update the App to get it working in last version of Android Studio Dolphin an Flutter 3.x. The last Update from June not working anymore.

Here are almost 750 comments. Most of them is about App code is not working. But many customers already purchased. Why did you sell it without any test? Please update it all as workable

Any Progress with new App Version??. It seems to be since 3 Months no support anymore.
