I am trying to add a player using Sliding Up Panel but the app crashes on startup. If you want to see my full code; https://github.com/Kailash8460/poptune.git

MainActivity.java

I know there are a lot of questions about that error. Tried many solutions, I realized something was different in my case. Can anyone please help? I tried to apply searchview to recyclerview, and inserted filter() in reyclerview adapter and setOnQueryTextListener in mainactivity.

I am trying to create an app. I want to change an attribute in a parent class (so it can display a Visibility item, SlidingUpPanel) after submitting a query in the child class (which is a search bar).

I've used SlidingUpPanel in my main class. and in the main class, I have a bottom sheet, and then clicking on the bottom sheets icon, load page. now when I've to use SlidingUpPanel, I have problem loading pages in the body. can anyone help me with how can I load pages of the bottom navigation in the body of SlidingUpPanel?

dependencies used:

• sliding_up_panel: ^1.0.2

• image_picker: ^0.6.6+5
