Advanced Flutter[2025]: BLoC, Injectable, Flavors, i18n, Dio

Build an e-commerce app using Flutter with BLoC, Injectable, Flavors, AutoRoute, i18n, Flavors, Dio & API integration

What you'll learn
- Learn how to connect your app to real-world backend services using Dio, handle responses, errors, and apply clean separation of concerns.
- Implement a scalable error-handling architecture to gracefully manage network failures, timeouts, and server errors with custom exceptions
- (Search &Filters) Implement powerful search features with advanced filtering capabilities to enhance the product discovery experience
- (Pagination) Efficiently load large datasets from APIs using scroll-based pagination techniques.
- (BLoC) State Management with BLoC along with Freezed to manage complex app states in a clean, scalable, and testable way
- (Code Generation with Freezed) Eliminate boilerplate by generating immutable model classes, union states for BLoC, and more using freezed.
- (Dependency Injection) Set up scalable and testable architecture using injectable and get_it, including support for multiple environments (flavors).
- (Dio) Build a robust and reusable API layer with Dio interceptors, and switch configurations based on app flavor (dev, staging, production).
- (AutoRoute with Guards) Use auto_route navigation 2.0 for clean, declarative navigation with route guards for protected routes (e.g., authentication).
- (Authentication Flow) Implement complete user authentication: login, signup, logout, and session persistence using Hive.
- (Offline Support with Hive) Store data locally with Hive for fast offline access and smoother user experience.
- (Internationalization (i18n) ) Add multi-language support to your app using Flutter's internationalization capabilities, making your app globally accessible.
- Implement Cart Management

Requirements
- You should know how to create simple Flutter apps.
- Understanding of widgets, navigation, and UI layouts.

Description
Are you ready to take your Flutter skills to the next level?In this advanced course, you'll build a complete e-commerce application from scratch using powerful Flutter tools and architectural patterns trusted by professionals.

You'll go beyond the basics and learn how to structure scalable, maintainable, and testable Flutter applications using:

BLoC (Business Logic Component)for state management

Injectable + GetItfor dependency injection

Diofor complete networking setup, API integration, interceptors, and error handling

AutoRoutefor advanced navigation

Freezedfor immutable models, union types, and sealed classes

Flutter i18nfor internationalization

Flavorsfor environment-based builds (dev, staging, production)

Hivefor local storage and lightweight data persistence

Along the way, you'll implement real-world features like user authentication, product listing with pagination support, cart management, search functionality with filtering support, and secure API communication — all while following best practices used by top Flutter developers.

This course is perfect for Flutter developers who are comfortable with the basics and want to build production-ready apps with professional tooling, advanced patterns, and scalable code structures.

Whether you're preparing for a job, freelancing, working on a team, or launching your own product — this course gives you the skills, confidence, and reusable code patterns to succeed in any advanced Flutter project.

Who this course is for:
- Flutter developers looking to level up by building real-world apps with best practices
- Anyone preparing for Flutter job interviews or building an MVP
- Developers who want to learn BLoC, Freezed, Dio, and dependency injection in-depth
- Anyone building scalable Flutter projects with clean architecture principles
