Connecting Flutter Apps to REST APIs
Mobile applications rely on backend APIs to fetch, sync, and persist data. Connecting your frontend app seamlessly to remote APIs is a core skill for any professional mobile engineer. This course covers the patterns and tools used to integrate Flutter apps with REST APIs. You will learn to perform HTTP requests using the http and Dio packages, parse nested JSON data structures, and handle errors robustly. You will build a resilient service layer featuring authentication interceptors, automatic request retries, and paginated infinite scroll lists.
Web Development Intensive
Curriculum Outcomes
Integrate complex remote APIs with Flutter using standard and advanced libraries
Parse complex, nested JSON payloads into type-safe Dart data models
Build a decoupled API service layer featuring custom interceptors and error handling
Implement robust OAuth2 token-based authentication and secure session storage
Construct paginated list views with infinite scrolling and loading states
Modules
Step-by-step masteryHTTP in Flutter
Covers standard HTTP request configurations. Students compare http vs. Dio libraries, serialize JSON to Dart model classes, and construct robust error handlers.
API Integration Patterns
Focuses on advanced service design. Covers authentication token management, interceptor pipelines, auto-retrying failed calls, and infinite list scroll configurations.
Project - API-Connected App
An intermediate project building an API-connected client. Students map data structures, write service endpoints, connect state selectors, and handle credential storage.
Capstone Project - FlutterConnect - Full API-Integrated Mobile App
Students build a comprehensive client dashboard featuring secure token login, session refresh interceptors, lazy-loaded feed grids, and detailed error handlers.
