About Flutter

Flutter provides a widget-based framework for building applications from a shared Dart codebase. Build a small application with responsive layouts, navigation, asynchronous data, and tests while checking platform-specific behavior rather than assuming identical behavior everywhere.

Flutter Course Objectives

  • Use Dart and Flutter's widget lifecycle to build an application.
  • Design responsive, accessible screens and forms.
  • Separate interface state from data access and business rules.
  • Handle navigation, asynchronous requests, and local persistence.
  • Test and package an application for an agreed target platform.

Pre-requisites

  • Programming experience with functions, objects, and asynchronous operations.
  • Basic HTTP and JSON knowledge.
  • Dart fundamentals are introduced; prior mobile-development experience is useful but not required.

Lab Setup

  • Flutter SDK, Dart tooling, Git, and a supported editor.
  • A configured Android emulator, physical test device, or browser target and supplied local API.
  • Verify target-platform toolchains with flutter doctor before teaching time. iOS builds require compatible macOS and Xcode tooling.

Detailed Course Outline

Dart Foundations

  • Types, null safety, collections, and functions
  • Classes, constructors, and interfaces
  • Futures, async/await, and streams
  • Package management and project organization

Flutter Application Structure

  • Widgets, elements, and the build process
  • Stateless and stateful widgets
  • Widget lifecycle and disposing resources
  • Hot reload, hot restart, and debugging

Layout and Styling

  • Layout constraints and sizing
  • Rows, columns, stacks, and scrolling lists
  • Themes, typography, and reusable components
  • Responsive and adaptive layouts

Interaction and Forms

  • Input widgets and focus handling
  • Form validation and error messages
  • Keyboard and accessibility support
  • Loading, empty, and retry states
  • Routes, navigation, and deep-link concepts
  • Local state and shared application state
  • Selecting a state-management approach
  • Keeping business rules outside widgets

Networking and Persistence

  • HTTP requests and JSON serialization
  • Asynchronous cancellation and lifecycle concerns
  • Local settings and data persistence
  • Handling offline and network-error cases

Platform Integration

  • Packages and plugin selection
  • Permissions and platform-specific configuration
  • Platform-channel responsibilities
  • Checking differences between target platforms

Testing and Performance

  • Unit, widget, and integration tests
  • Flutter DevTools and layout inspection
  • Avoiding unnecessary rebuilds
  • Profiling scrolling and resource usage

Packaging and Release

  • Build modes and environment configuration
  • Assets, app identifiers, and signing concepts
  • Reproducible builds for the agreed target
  • Release checks and dependency maintenance

Practical Exercise

  • Build a multi-screen application using a supplied API
  • Validate a form and preserve state across navigation
  • Test successful, empty, and failed data requests
  • Produce a target-platform build and a test/report checklist
