Redux Toolkit setup in React Native - UI Render Trace

Component - Redux Toolkit setup

This UI component shows how to set up Redux Toolkit in a React Native app. It creates a store, provides it to the app, and connects a simple counter component to the store.

Widget Tree

Provider
└── App
    └── View
        ├── Text (Counter Display)
        └── Button (Increment)

The Provider wraps the whole app to give access to the Redux store. Inside App, a View contains a Text showing the counter value and a Button to increase it.
