Building Your First Flutter App with Vibe Coding
A beginner-friendly guide to using Flutter, a mobile boilerplate, and AI coding agents to build a maintainable first app instead of a prototype that only works once.
Begin with the project conventions
Ask your AI agent to identify the app entry point, routing, state management, theme, data layer, and test commands. Do not let every prompt introduce a new package or architectural style. Consistency is more valuable than novelty in a first app.
Build reusable screens, not one-off widgets
Create a small design language early: spacing, text styles, colors, buttons, inputs, cards, and loading indicators. Ask Codex or another agent to reuse those primitives. A boilerplate can provide this foundation so your prompts focus on the product experience.
Keep business logic outside widgets
The UI should display state and dispatch actions. Authentication, validation, API calls, and persistence should live in testable services or controllers. This separation makes future AI changes safer because the agent can modify one layer without rewriting the entire screen.
Test on both platforms
An app can look correct on an Android emulator and still have keyboard, safe-area, permissions, or navigation issues on iOS. Test the core journey on both platforms before calling the feature complete.
Keep the first Flutter release focused
Start with one polished flow, responsive layouts, good empty states, and reliable error recovery. A smaller app with clear value is more useful than a large generated app with half-finished screens.
