Flutter Course for Beginners

Lesson 1 • Dart Language Core Concepts

Cover Dart variables, types, functions, and control flow. Dart proficiency is required before writing any Flutter widget logic.

Lesson 2 • Setting Up the Development Environment

Install Flutter SDK, configure an IDE, and connect a device or emulator. This foundation ensures every subsequent exercise runs without setup friction.

Lesson 3 • Object-Oriented Programming in Dart

Apply classes, inheritance, mixins, and interfaces to model real-world objects. These OOP patterns underpin every Flutter widget and state class.

Lesson 1 • Core Layout Widgets

Use Row, Column, Stack, and Expanded to arrange UI elements precisely. Layout mastery is the prerequisite for building any real screen.

Lesson 2 • Stateless and Stateful Widgets

Distinguish immutable stateless widgets from mutable stateful ones and choose the right type. Correct widget choice prevents unnecessary rebuilds and bugs.

Lesson 3 • Input and Form Widgets

Capture user input with TextField, Form, and validation logic. Forms are the primary data-entry mechanism in most production apps.

Lesson 4 • Scrollable and List Widgets

Build scrollable interfaces with ListView, GridView, and CustomScrollView. Efficient list rendering is critical for data-heavy Flutter apps.

Lesson 1 • Material Design and Theming

Configure MaterialApp ThemeData to set colours, typography, and component styles globally. A unified theme reduces redundant styling code across the app.

Lesson 2 • Responsive and Adaptive Layouts

Use MediaQuery, LayoutBuilder, and breakpoints to adapt layouts to phones, tablets, and desktops. Responsive design is mandatory for multi-platform Flutter apps.

Lesson 3 • Animations and Visual Effects

Implement implicit and explicit animations to enhance user experience. Smooth transitions signal quality and guide user attention effectively.

Lesson 1 • Dialogs, Sheets, and Overlays

Display modal dialogs, bottom sheets, and snack bars for contextual user interactions. Overlays communicate feedback without full-screen navigation.

Lesson 2 • Bottom Navigation and Tab Bars

Combine BottomNavigationBar and TabBar with persistent state across tabs. Tab-based navigation is the dominant pattern in consumer mobile apps.

Lesson 3 • Navigator 1.0 Basics

Push and pop routes imperatively using Navigator.push and named routes. This approach covers the majority of simple app navigation needs.

Lesson 1 • BLoC Pattern with flutter_bloc

Separate business logic from UI using Events, States, and Cubits. BLoC enforces strict unidirectional data flow suited to large team codebases.

Lesson 2 • Riverpod for Reactive State

Declare providers outside the widget tree with Riverpod for compile-safe, testable state. Riverpod eliminates context dependency and simplifies async state.

Lesson 3 • InheritedWidget and Provider

Share state across the widget tree with InheritedWidget, then simplify it using the Provider package. Provider is the gateway to scalable state management.

Lesson 1 • Relational Data with SQLite

Define schemas, run queries, and manage migrations using the sqflite package. SQLite handles structured offline data that key-value stores cannot.

Lesson 2 • Advanced Networking with Dio

Use Dio interceptors, request cancellation, and multipart uploads for production-grade networking. Dio provides features the basic http package lacks.

Lesson 3 • Real-Time Data with Firebase

Connect to Firestore and Realtime Database for live data sync across devices. Firebase accelerates backend development without managing a custom server.

Lesson 4 • HTTP Requests and REST APIs

Send GET, POST, PUT, and DELETE requests using the http package and handle responses. REST integration is the most common data source in mobile apps.

Lesson 1 • Unit Testing Dart Logic

Test pure Dart functions and classes with the test package and mock dependencies using Mockito. Unit tests validate business logic independently of the UI.

Lesson 2 • Debugging with Flutter DevTools

Use DevTools to inspect the widget tree, profile CPU and memory, and detect jank. Profiling skills separate performant apps from sluggish ones.

Lesson 3 • Widget Testing

Render widgets in a test environment and simulate user interactions with WidgetTester. Widget tests catch UI regressions without a physical device.

Lesson 1 • Signing and Release Builds

Generate signing keys, configure Gradle and Xcode for release, and produce signed artifacts. Signing is a mandatory step before any store submission.

Lesson 2 • Flutter Web and Desktop Deployment

Build and host Flutter web apps and configure desktop targets for Windows, macOS, and Linux. Multi-platform deployment maximises app reach from a single codebase.

Lesson 3 • App Configuration and Flavours

Manage app identifiers, permissions, and build flavours for dev, staging, and production. Proper configuration prevents environment-specific bugs in production.
