Pull request overview

This PR refactors the events logic in react-native-video from a property-based callback system to a subscription-based event listener pattern. The main changes include converting event callbacks from settable properties (onEvent: (arg) => void) to methods that return ListenerSubscription objects (addOnEventListener((arg) => { callback }): ListenerSubscription). Additionally, the Nitro modules dependency is updated from version 0.30.0 to 0.31.0.

Key changes:

• Introduced ListenerSubscription interface with a remove() method for managing event subscriptions
• Converted all event properties to addOn*Listener() methods in both VideoPlayerEventEmitter and VideoViewViewManager
• Updated event handling in VideoView.tsx to register/cleanup subscriptions via useEffect hooks
• Refactored VideoPlayerEvents class to use the new subscription-based API
