Original post Build a Flutter app with Very Good CLI and AWS Amplify
Article Summary
Very Good Ventures shows how to build production-ready Flutter authentication in hours, not days. Their approach combines AWS Amplify with battle-tested architecture patterns for 100% test coverage.
This comprehensive tutorial demonstrates integrating AWS Amplify authentication into a Flutter app using Very Good CLI and layered architecture. The guide walks through everything from AWS IAM setup to implementing sign-in, sign-up, and confirmation flows with proper separation of concerns.
Key Takeaways
- Very Good CLI generates starter apps with layered architecture and full test coverage
- AWS Amplify provides authentication, storage, and GraphQL APIs through simple CLI commands
- Custom auth_client package abstracts Amplify implementation from business logic

What This Article Covers
Flutter developers using AWS Amplify often struggle with authentication. Managing sign-up, sign-in, and confirmation code verification requires careful attention to clean architecture and test coverage.
Very Good Ventures built a layered architecture with custom auth_client and user_repository packages. These packages wrap AWS Amplify's AmplifyAuthCognito plugin. They paired this with BLoC state management and Formz for form validation across multiple features.
The tutorial shows how to achieve 100% test coverage with production-ready authentication. It uses modular packages and AWS Amplify's pre-built UI components with email verification. Developers can now build full-stack Flutter apps that follow enterprise-grade security patterns.
