My Question or Issue

I am developing an app using the Spotify Web API with Flutter. I want to support playback in the app. I was attempting to use a web view to host the web playback sdk to serve as the player for the app.

Current State: On iOS, the song will play for 10 seconds and then stop. On android, the song will not play at all.

My question is:

Is my goal possible? Is there any Flutter SDK that works for both iOS and android that would support playback?
