Flutter App Development Training in Pune with Placement

Dart taught as a language before any widget appears. Variables and types, sound null safety and what `late` really promises, control flow, functions with named and optional parameters, classes, mixins and extension methods.

Dart 3 gets proper coverage because it changed how idiomatic Dart reads: records for lightweight multiple returns, pattern matching and destructuring, sealed classes with exhaustive switch expressions, and class modifiers. Asynchrony closes the week — `Future`, `async`/`await`, `Stream`, and the difference between a single-subscription and a broadcast stream.

The toolchain and the shape of a Flutter project. SDK installation with `flutter doctor` resolved properly on Windows and macOS, IDE setup in Android Studio or VS Code, and emulator plus physical-device runs on both platforms.

Then the project itself: `pubspec.yaml`, dependency and dev-dependency management, version constraints, assets and fonts, and platform folders. Hot reload versus hot restart is taught with its actual limits — what state survives, what does not, and why a `const` constructor sometimes stops a reload appearing.

Flutter is widgets all the way down, and the tree is the mental model everything else depends on. StatelessWidget versus StatefulWidget, the `build` method, `BuildContext` and what it can and cannot reach, the element tree, and keys — including the classic bug where reordering a list scrambles state because keys were omitted.

Layout follows: Column, Row, Stack, Container, Padding, Expanded and Flexible, Wrap, and the constraint model — constraints go down, sizes go up, parent sets position — which is the sentence that resolves most layout confusion.

Making an app look right on both platforms and on every screen size. The Material 3 widget set as the default, Cupertino widgets where an iOS-native feel is wanted, and an honest position on adaptive versus uniform design.

Theming covers ThemeData, colour schemes, typography, component themes and dynamic colour, plus light and dark mode. Responsive layout uses LayoutBuilder, MediaQuery, OrientationBuilder and breakpoints for phone, tablet and foldable, with safe areas, text scaling and accessibility handled as requirements.

State management as Pune Flutter teams actually do it, starting with why `setState` stops scaling. Riverpod is the modern default for new projects: providers and their variants, `ConsumerWidget` and `ref`, `AsyncValue` for representing loading, data and error in one type, and the `AsyncNotifier` pattern.

Code generation with `riverpod_generator` removes the boilerplate and gives compile-time safety. The module also covers provider scoping and overrides — the mechanism that makes Riverpod genuinely testable — plus dependency injection and caching with `keepAlive`.

The pattern a large share of Pune Flutter teams standardise on, and the one most likely to appear in an interview. Cubit first as the simpler form — states as immutable classes, `emit`, and `BlocBuilder`. Then full Bloc with events, event transformers for debounce and throttle, and `BlocListener` versus `BlocConsumer` for side effects.

State modelling gets real attention: sealed state classes with exhaustive handling, `Equatable` for correct rebuild behaviour, and `BlocObserver` for logging. The module ends with an honest comparison of Riverpod and Bloc, and guidance on choosing per team.

Routing that survives an app growing past ten screens. `go_router` as the modern default replacing hand-rolled `Navigator` calls: declarative route definitions, path and query parameters, nested and shell routes for persistent bottom navigation, and typed routes via code generation.

Redirection and route guards handle authentication flows, including the redirect-after-login pattern every real app needs. Deep linking closes the module — custom schemes, Android App Links and iOS Universal Links, with the platform configuration and verification each requires.

Input handling done to a production standard. The `Form` widget and `GlobalKey<FormState>`, `TextFormField`, controllers and focus nodes, and validation that runs at the right moment rather than on every keystroke.

Complex forms use `flutter_form_builder` or a reactive-forms approach, with cross-field validation and async validation against a backend. The module covers keyboard handling and the overflow it causes, input formatters and masks for phone and PAN entry, and accessibility — labels, focus order and error announcement.

The data layer's outward half. `http` for simple cases and Dio where interceptors, cancellation and upload progress matter — authentication and retry interceptors, timeouts tuned for poor networks, and structured error mapping.

JSON serialisation uses `json_serializable` with `build_runner`, including nested models and schema-mismatch tolerance. GraphQL is covered with `graphql_flutter` for teams on that stack, and the module ends on file upload and download, and mocking HTTP for tests.

Data that outlives the process. Drift as the typed Dart ORM over SQLite — tables, queries, joins, migrations and reactive streams that push updates into the UI. Isar as the NoSQL alternative, `shared_preferences` for simple key-value, and `flutter_secure_storage` for tokens.

Offline-first is the point of the module: the local database as single source of truth, a repository that reconciles remote and local, queued mutations while offline, conflict resolution, and connectivity awareness — the design Indian consumer apps need on unreliable networks.

Firebase as the backend most Flutter projects reach for first. FlutterFire setup across both platforms, Firebase Auth with email, Google and phone-number sign-in — the last dominant in the Indian market — and Firestore data modelling with real-time listeners.

Security rules are written and tested rather than left permissive. Cloud Storage handles user media, Cloud Messaging handles push including foreground, background and terminated-state delivery, and Crashlytics, Analytics and Remote Config close the module with a real crash report read and fixed.

The layer that makes an app feel considered rather than merely functional. Implicit animations (`AnimatedContainer`, `AnimatedOpacity`, `TweenAnimationBuilder`) for the common cases, then explicit animation with `AnimationController`, `Tween` and curves, and staggered sequences.

Hero transitions connect screens, and `CustomPainter` with `Canvas` covers charts, progress indicators and shapes no widget provides. Rive and Lottie integrate designer-produced motion, and the module ends on performance — keeping animation off the build phase and respecting reduced-motion settings.

Reaching past Dart when the platform requires it. Method channels for request-response calls into Kotlin and Swift, event channels for native-to-Dart streams, and the serialisation and threading rules that make channel code correct.

Pigeon generates type-safe channel bindings and removes the string-keyed fragility of hand-written ones. Dart FFI calls C libraries directly, and the module covers plugin package structure, federated plugins, platform permissions on each side, and the practical question of when to write a plugin versus find one.

Verifying and tuning what you built. Unit tests with the `test` package, widget tests with `flutter_test` including pumping, finders and matchers, golden tests for visual regressions, and integration tests via `integration_test` on a real device.

Mocking with `mocktail` and fakes for repositories keeps tests fast. Performance covers DevTools timeline and CPU profiling, the Impeller renderer, diagnosing jank and shader compilation stalls, `const` constructors and rebuild scope, list virtualisation and image caching, and memory-leak hunting.

Shipping to two stores from one codebase. Android release builds — keystore signing, App Bundle output, R8 and Dart obfuscation, and the Play Console flow with its Data Safety form and target-API requirements. iOS release — certificates, provisioning profiles, App Store Connect, TestFlight and the review-rejection causes that catch first-time submitters.

Build flavours and environment configuration keep dev, staging and production separate. CI/CD with Codemagic, Bitrise or GitHub Actions automates build, test, sign and upload for both platforms.

Full-time capstone work followed by structured interview preparation. You build and release a complete cross-platform application — Riverpod or Bloc state management, go_router navigation, a Dio data layer with Drift-backed offline-first storage, Firebase auth and push, animations, tests, and signed builds on both stores' test tracks.

Interview preparation matches Pune Flutter panels: a Dart and async round, a widget-tree and rendering round, a state-management round where you defend your choice, and a system-design round on offline sync. Resume, LinkedIn and GitHub polish included.
