How to Get More Out of Cursor When Your Flutter Project Has Structured AI Context

FlutterInit projects ship Cursor rules plus AGENTS.md and DESIGN.md. Here’s how to use that context so agents extend your stack instead of rewriting it.

Cursor works best when the repo already knows its own rules. A FlutterInit project drops .cursor/rules/flutter-project.mdc (always apply) plus AGENTS.md and DESIGN.md. Your job is to point the agent at work, not re-explain Riverpod vs Bloc every chat.

What Cursor already knows

The generated Cursor rule includes:

  • Stack summary (architecture, state, navigation, backend)
  • Architecture and state-management rules
  • Navigation and networking conventions
  • Pointers to AGENTS.md, DESIGN.md, and SETUP.md for deep work

You don’t need to paste “we use Feature-First and go_router” into every prompt. Start with the feature.

Prompts that work on a FlutterInit repo

Good: “Add a todos feature following AGENTS.md. Domain entity, repository interface, data impl, Riverpod notifier, screen, and a go_router route.”

Bad: “Build a todo app with state management and Firebase however you want.”

The first prompt respects zones. The second invites a parallel architecture.

Use DESIGN.md for UI work

Before restyling screens, tell Cursor to read DESIGN.md. It documents:

  • Theme preset and Material 3 / Cupertino notes
  • context.colors / context.appColors (no hardcoding hex)
  • Typography roles
  • AppSpacing, AppBorders, AppShadows, AppDurations

Agents that skip DESIGN.md invent one-off paddings and colors. Agents that read it reuse tokens.

Safe zones vs caution zones

AGENTS.md splits the tree:

  • Safe: feature folders, shared widgets, tests
  • Caution: app_router.dart, main.dart, app_config.dart, theme, pubspec
  • Don’t touch: native folders, secret .env values

Ask for changes in safe zones first. When you must touch routing or config, say so explicitly and ask for a minimal diff.

Verification loop

After an agent change, run what AGENTS.md already recommends:

BASH
flutter pub get
flutter analyze
flutter test

If the stack uses AutoRoute or MobX codegen, run build_runner as documented in the generated notes.

Pair with Claude Code

Same project can use Cursor and Claude Code. FlutterInit emits both .cursor/rules and CLAUDE.md so you’re not maintaining two hand-written briefs.

More on that in Why We Generate CLAUDE.md and AGENTS.md. For the generation philosophy, see Deterministic Generation vs AI Boilerplate.

Scaffold a stack on /create, then open Cursor on the unzipped project and try one feature add — you’ll feel the difference.
