Udemy – Advanced Flutter[2025]: BLoC, Injectable, Flavors, i18n, Dio 2025-8

Advanced Flutter[2025]: BLoC, Injectable, Flavors, i18n, Dio. This course enables developers to build a complete, industrial-grade e-commerce application from the ground up. The course focuses on using professional architectural patterns and modern tools to create scalable, maintainable, and testable applications. Key technologies covered include the BLoC architecture for state management, the Injectable and GetIt libraries for dependency injection, and Dio for robust network communications including API integration, request tracking, and error handling. It also uses AutoRoute for advanced routing, Freezed for creating safe and immutable models, Flutter i18n for multilingual support, and Flavors for different configurations of development, staging, and production environments. Data storage is also handled with Hive. During the course, participants will implement practical features such as authentication system, paginated product display, shopping cart management, advanced search and filtering, and secure connection to the backend. This course is designed for developers who have mastered the basics of Flutter and who aim to build production-ready applications with enterprise development best practices and patterns.

What you will learn

• Connecting your application to backend services: You will learn how to connect your application to real backend services using Dio, handle responses and errors, and enforce clean isolation.
• Fault Management Architecture: You implement a scalable fault management architecture to properly handle network failures, timings, and server errors with custom exceptions.
• Search and Filters: You implement powerful search features with advanced filtering capabilities to improve the product discovery experience.
• Pagination: Load large data from APIs efficiently using scroll-based pagination techniques.
• State Management with BLoC: You will learn state management with BLoC and Freezed to manage complex application states in a clean, scalable, and testable way.
• Code generation with Freezed: Eliminate redundant code by generating immutable model classes, union states for BLoC, and more using Freezed.
• Dependency Injection: You set up a scalable and testable architecture using injectable and get_it, including support for multiple environments (flavors).
• Dio: You build a robust and reusable API layer with Dio interceptors and change configurations based on the application version (dev, staging, production).
• AutoRoute with Guards: You use auto_route navigation 2.0 for clean, declarative routing with route guards for protected routes (such as authentication).
• Authentication Flow: You implement a complete user authentication flow including login, registration, logout, and session persistence using Hive.
• Offline support with Hive: Store data locally with Hive for fast offline access and a smoother user experience.
• Internationalization (i18n): Using Flutter’s internationalization capabilities, you add multilingual support to your application to make it globally accessible.
• You implement shopping cart management.

This course is suitable for people who:

• Flutter developers: People looking to improve their skills by building real apps using best practices.
• Job seekers: Anyone preparing for Flutter job interviews or building an MVP.
• Developers who want to learn BLoC, Freezed, Dio, and dependency injection in depth.
• Anyone who builds scalable Flutter projects with clean architectural principles.
