Flutter Build Guides
Step-by-step Flutter guides for the features every app needs — auth, payments, AI. Each one shows the hand-rolled path, then how The Flutter Kit ships it pre-wired.
Last updated: 2026-06-02
These Flutter guides walk through adding the features that take the longest to wire correctly — Firebase auth, RevenueCat payments, OpenAI chat — with real Dart code. They're honest tutorials: follow them to build it yourself, or use The Flutter Kit ($69 one-time) to skip straight to a production-ready version with all of it already integrated.
