🌿 envified

Stop rebuilding. Start switching. ⚡
Runtime environment magic for Flutter apps. No hot reload needed.

The Problem

You're a Flutter developer. Every time you need to test a different API endpoint—local dev server, staging, production—you rebuild the app. With --dart-define flags. Or .env files baked into the binary. Or multiple entry points. It's tedious. It's error-prone. It breaks flow.

What if you could swap environments in 0.2 seconds? No rebuild. No compilation. Just tap, tap, done.

That's envified.

What is envified?

envified is a production-grade environment manager for Flutter that lives entirely at runtime.

• 🚀 Swap dev ↔ prod in 200ms — no rebuild, no hot reload
• 🔒 Prod lock by default — prevent accidental data disasters
• 🧪 Override any URL — test against local tunnels, PR branches, anywhere
• 🔐 Premium PIN gate — secure the debug panel with glassmorphic UI
• 📋 Full audit trail — log every switch and URL change
• ⚙️ Zero production overhead — stripped out completely in release builds
• 🎨 Premium debug UI — dark-luxury design, fully customizable

It's not just a config switcher. It's enterprise-grade security meets developer quality of life.

🚀 Zero-Config Auto-Discovery (v2.1.0+)

envified now automatically scans your assets/env/ directory for any .env.* files. No manual mapping required!

// No need to specify URLs — they're discovered automatically!
await EnvConfigService.instance.init();

// ✅ Finds .env.dev, .env.staging, .env.prod, .env.uat, etc.
// ✅ Extracts BASE_URL from each
// ✅ Auto-populates the UI

The debug panel automatically generates buttons for every discovered environment. A standalone .env file is treated as Production by default.

Quick Start (3 Steps)

1️⃣ Install

dependencies:
  envified: ^2.1.0

2️⃣ Add .env Files

Create in assets/env/:

# .env.dev
BASE_URL=https://dev.api.myapp.com
DEBUG=true

# .env.prod
BASE_URL=https://api.myapp.com
DEBUG=false

Register in pubspec.yaml:

flutter:
  assets:
    - assets/env/

3️⃣ Initialize

In main.dart, before runApp():

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await EnvConfigService.instance.init(
    defaultEnv: Env.dev,
    allowProdSwitch: false,    // ⚠️ Lock prod by default
    verifyIntegrity: true,     // 🔐 Detect tampering (Prod only)
  );

  runApp(const MyApp());
}

Wrap your app with the overlay:

MaterialApp(
  builder: (context, child) => EnvifiedOverlay(
    service: EnvConfigService.instance,
    enabled: kDebugMode,                        // 🚫 Hidden in production
    gate: EnvGate(pin: '1234'),                 // 🔐 Secure PIN gate
    child: child ?? const SizedBox.shrink(),
  ),
  home: const MyApp(),
)

Core Usage Patterns

Reading Values

final svc = EnvConfigService.instance;

final name     = svc.get('APP_NAME');
final timeout  = svc.getInt('TIMEOUT', fallback: 30);
final debug    = svc.getBool('DEBUG');
final apiUrl   = svc.getUri('BASE_URL');

Reacting to Switches

EnvConfigService.current is a ValueNotifier.

EnvConfigService.instance.current.addListener(() {
  final config = EnvConfigService.instance.current.value;
  dio.options.baseUrl = config.baseUrl;
  print('Active env: ${config.env.name}');
});

---

Security & Production Safety

🔒 Production Lock

By default, allowProdSwitch: false locks the production environment. Once the app starts in a production-identified environment (e.g., via .env.prod), switching is disabled.

✅ Tamper Detection

When verifyIntegrity: true is set, envified computes a SHA-256 hash of your production .env files. If the files are modified (e.g., on a rooted device), it throws EnvifiedTamperException.

⚙️ Zero Production Overhead

All debug components (buttons, panels, gates) are wrapped in kDebugMode checks. Flutter's tree-shaker removes them entirely from release builds. Zero bytes added to your production IPA/APK.

🔄 API Reference

Env (Class)

Replaced the enum with a dynamic class.

• Env.dev, Env.staging, Env.prod (Standard constants)
• Env.fromFileName(name) (Factory for discovered files)
• env.isProduction (Boolean flag)

EnvConfigService

• init(): Discover files and load state.
• switchTo(Env): Change environment at runtime.
• setBaseUrl(url): Override the current URL.
• current: ValueNotifier<EnvConfig>.
