🔑 Golden Rule: Optimize only when needed — don’t overcomplicate.

🔒 Flutter Security Essentials: Protect Your App

Worried about app security? Let’s explore how to keep your Flutter app safe.

🔸 Why Security Matters
A secure app builds trust and protects user data.

1️⃣ Secure Storage
• Use flutter_secure_storage
• Keep tokens & passwords safe

2️⃣ Data Encryption
• Encrypt sensitive local data
• Use HTTPS for all API calls

3️⃣ API Keys Protection
• Never hardcode keys
• Use environment variables or backend proxies

4️⃣ Authentication
• Implement OAuth2 or Firebase Auth
• Always validate on the server

5️⃣ Obfuscation
• Run flutter build apk --obfuscate
• Makes reverse-engineering harder

🔑 Pro Tip: Security is not one-time — keep updating & auditing.

🌍 Flutter Internationalization (i18n): Go Global

Ready to launch worldwide? Let’s see how Flutter handles multiple languages.
