React Native Development Training in Pune with Placement

React Native from a React-aware starting point, beginning with the differences that actually trip people up. There is no DOM — the primitives are `View`, `Text`, `Image`, `ScrollView` and `FlatList` — and `StyleSheet` is not CSS: no cascade, no inheritance beyond text, a different unit model.

The New Architecture is covered because it is the default from 0.76: the Fabric renderer, TurboModules, JSI and Bridgeless mode, and what each changed relative to the old asynchronous bridge. Understanding it is what lets you answer performance questions credibly in an interview.

Expo is the recommended path for most new apps, and the course treats it as the default rather than a beginner's shortcut. The managed workflow, the Expo SDK module set, and config plugins for native configuration without ejecting.

Expo Router provides file-based navigation with typed routes, layouts and nested stacks. The critical distinction between Expo Go and a custom development build is taught early, since Expo Go silently lacks any native module outside the SDK — the cause of a great deal of beginner confusion. Prebuild and the bare workflow close the module.

Building screens that behave on both platforms. Flexbox in React Native — same concepts as web with different defaults, `flexDirection: column` being the one that surprises everyone — plus absolute positioning, aspect ratio and percentage sizing.

Safe areas, notches, the home indicator and keyboard avoidance are handled properly rather than with magic numbers. Lists get real attention: `FlatList` and `SectionList` configuration, `keyExtractor`, `getItemLayout`, and FlashList for the long lists where FlatList starts to drop frames.

Styling at the scale of a real app rather than a demo screen. The `StyleSheet` API and its performance characteristics, composition and conditional styles, and the platform-specific style patterns that keep one codebase looking correct on both.

NativeWind brings Tailwind syntax to React Native and is the fastest-growing choice in Pune teams; styled-components is covered as the alternative. The module builds a small design system — tokens, spacing scale, typography, themed components — plus dark mode, dynamic text sizing and accessibility contrast.

Modern React applied in a mobile context. The core hooks revisited where mobile changes the calculus — `useState`, `useEffect` and its cleanup discipline, `useMemo` and `useCallback` and when they genuinely help, `useRef` for imperative handles.

React 19 additions get direct treatment: `useTransition` for keeping input responsive, `useOptimistic` for instant-feeling mutations on slow networks, and `use` for promise consumption. The React Compiler removes most manual memoisation, and the module is explicit about what it does and does not cover. Custom hooks and Context close it.

React Navigation 7 is the de-facto routing library and the layer Expo Router is built on, so it is taught directly. Native stack, bottom tabs, top tabs and drawers; nesting navigators without creating the state bugs that nesting invites; and modals and presentation styles per platform.

Params and typed navigation with TypeScript keep routes safe. Auth flows use the conditional-navigator pattern rather than imperative resets. Deep linking covers URL configuration, Android App Links, iOS Universal Links, and handling a link that arrives on a cold start.

Two subjects that transfer directly from web React, which is precisely why they are worth doing well. React Hook Form with Zod for schema validation — the same stack Pune web teams use, so the skill moves in both directions — plus controlled inputs, focus management and keyboard handling on mobile.

Server state uses TanStack Query: queries and mutations, cache keys and invalidation, optimistic updates with rollback, pagination and infinite queries, and background refetch. Persisting the query cache and `NetInfo` awareness make the app behave sensibly offline.

Animation that runs on the UI thread rather than the JavaScript one, which is the difference between smooth and janky on a mid-range Android device. Reanimated 3 shared values, `useAnimatedStyle`, worklets and the threading model that makes them work.

WithTiming, withSpring and withSequence cover the common motion vocabulary; layout animations and entering and exiting transitions handle list and screen changes. Scroll-driven animation, interpolation and `react-native-skia` for advanced graphics close the module, with reduced-motion respected throughout.

The features that distinguish a real app from a web page in a shell. Gesture Handler 2 — tap, pan, pinch, long press and swipeable rows — composed with Reanimated for natively responsive interaction, including a bottom sheet built rather than installed.

Device capabilities follow: camera and media library, location and background geolocation, push notifications end to end, secure storage, biometric authentication with `expo-local-authentication`, haptics, and the permission flows and rationale screens each of these requires on both platforms.

What to do when no package exists. First the judgement call — when a native module is genuinely required versus when a community package or config plugin will do — then the mechanics.

TurboModules under the New Architecture with codegen and type-safe interfaces, and the Expo Modules API as the modern authoring path: TypeScript on the React side, Swift and Kotlin on the native side, with far less boilerplate than the classic bridge. The module covers native view components, autolinking, patching a third-party package with `patch-package`, and testing native code.

Correctness and speed. Jest for unit tests, React Native Testing Library for component tests written against user-visible behaviour, mocking native modules, and end-to-end coverage with Maestro or Detox.

Performance starts with the Hermes engine — bytecode precompilation, startup cost and memory — then profiling with React Native DevTools and the Performance Monitor. The module works through the real causes of jank: re-render storms, unvirtualised lists, oversized images, expensive `useEffect` chains, and bundle size with Hermes source maps for production stack traces.

Shipping to both stores from one codebase, without owning a Mac for the iOS half. EAS Build for cloud builds with build profiles for development, preview and production; credential management, keystores and provisioning handled by EAS; and EAS Submit for automated store upload.

The store flows are covered concretely: the Play Console with its Data Safety form and target-API requirements, and App Store Connect with TestFlight and the review rejections that catch first submissions. EAS Update delivers over-the-air JavaScript changes, with an honest account of what OTA may and may not change under store policy.

Full-time capstone work followed by structured interview preparation. You build and release a complete cross-platform application — Expo Router navigation, TanStack Query server state with offline persistence, Reanimated interaction, camera or location, push notifications, tests, and EAS builds submitted to both stores' test tracks.

Interview preparation matches Pune React Native panels: a React and hooks round, a React Native internals round on the New Architecture and rendering, a performance-debugging round, and a mobile system-design round. Resume, LinkedIn and GitHub polish included.
