Explain

NativeBase provides ready-to-use components like Buttons, Inputs, Modals, and more.

It works across iOS and Android, offering a unified look and feel.

It supports theming, responsive layouts, and integration with React Native ecosystem libraries.

Support for gestures and animations via React Native APIs

Basic Concepts Overview

NativeBaseProvider: top-level provider for theme and context

Components: building blocks for UI

Utilities: props for spacing, color, typography

Theming: light/dark mode and custom themes

Responsive design: adjust layouts for different screen sizes

Project Structure

App.js / index.js - entry point

components/ - reusable NativeBase UI components

screens/ - app screens using NativeBase
