Flutter E-commerce App Build

I want a complete, production-ready e-commerce mobile application written in Flutter and handed over within the next month. The core flow is familiar—secure user sign-up/sign-in, browsable product catalogue, cart, and a seamless checkout with payment integration—yet I expect the execution to feel polished and scalable. Clean, well-documented code, intuitive UI, and thoughtful state management are non-negotiable because I maintain and extend the project myself once it goes live.

You’ll be working directly with me: I hold an MCA, have already shipped full-stack e-commerce and reminder apps, and value clear technical discussions and fast feedback loops. That means you’ll get concise requirements, quick answers, and decisive reviews so we keep momentum.

Deliverables I need from you:
• Flutter source code in a private Git repository
• A reproducible build guide and one signed APK/AAB for testing
• Brief documentation on architecture choices, third-party packages, and payment gateway setup

Show me your most relevant Flutter commerce work, mention your preferred state-management pattern (Provider, Bloc, Riverpod, etc.), and outline how you plan to meet the one-month window. Let’s build something reliable, maintainable, and user-friendly together.
