movietray's Issues

Progress bar is keep on loading even though the network call is completed and the error message is displayed.

it can be fixed by showing the loader only when the state is loading in the LoadStateViewHolder.

Shared element transition to specific movie

It would be cool to see shared element transition to movie page and back :)

Try to find issues with the app and propose a solution.

The app is built in Kotlin with the architectural pattern, dependency injection and Navigation component integrated.

Run the app -> try to find issues -> Write down the steps to reproduce -> Propose a solution for the issue

The progress bar is displayed even after the network call is completed and the error message toast is displayed.

@niharika2810 can I work on this issue, can you assign this to me?

There is no retry option or any button to retry if the data is empty or if it's the first time the user has opened and without an internet connection.

@niharika2810 i would like to work on this one too
