prprompts-flutter-generator: Command for Claude Code

Generate Complete PRPROMPTS Folder

IMPORTANT: Generate a complete, secure, and adaptive PRPROMPTS/ folder for a large-scale Flutter project using Clean Architecture, BLoC/Cubit, and dynamic team structuring.

DEFINITIONS

PRP (Prompt Reference Pattern)

Every file MUST follow this exact structure:

## FEATURE
What this guide helps you accomplish

## EXAMPLES
Real code with actual file paths (e.g., lib/features/login/presentation/login_page.dart)

## CONSTRAINTS
✅ DO / ❌ DON'T rules

## VALIDATION GATES
Manual checklist + automated CI checks

## BEST PRACTICES
Junior-friendly explanations with "Why?" sections

## REFERENCES
Official docs, compliance guides, internal ADRs

Clean Architecture

Uncle Bob's layered approach:

• Presentation Layer: UI, BLoC/Cubit, Widgets
• Domain Layer: Entities, Use Cases, Repository Interfaces
• Data Layer: Repository Implementations, Data Sources, Models

JWT in Flutter (CRITICAL)

• ❌ NEVER sign tokens in Flutter
• ✅ Backend signs tokens (e.g., Node.js with node-jsonwebtoken, RS256)
• ✅ Flutter only verifies tokens using public key (dart_jsonwebtoken package)
• ❌ NEVER store private keys or secrets in Flutter code
• ✅ Always verify claims: aud, iss, exp, sub

Example (Backend - Node.js):

const token = jwt.sign(payload, privateKey, {
  algorithm: 'RS256',
  expiresIn: '15m',
  audience: 'my-flutter-app',
  issuer: 'api.example.com'
});

Example (Flutter - Verification Only):

import 'package:dart_jsonwebtoken/dart_jsonwebtoken.dart';

Future<bool> verifyToken(String token) async {
  try {
    final jwt = JWT.verify(
      token,
      RSAPublicKey(publicKeyString),
      audience: Audience(['my-flutter-app']),
      issuer: 'api.example.com',
    );
    return jwt.payload['exp'] > DateTime.now().millisecondsSinceEpoch / 1000;
  } catch (e) {
    return false;
  }
}
