We are building a social network application likes OwnMates but we couldn't find a good solution, which language is good either Kotlin or flutter?

Guidelines

Short version: for a social-network MVP like OwnMates, Flutter is usually the faster choice — not because it's inherently "better" than Kotlin, but because one codebase covers Android + iOS and lets a small team move quickly.

Why Flutter often wins for an MVP:

• Single Dart codebase → Android, iOS (plus web/desktop later), so you ship features roughly twice as fast as maintaining two native apps.
• Hot reload keeps product iterations cheap, which matters while you're still validating the idea.
• Ecosystem: you pair it with a BaaS (Firebase or Supabase) for auth, realtime chat, push notifications, and storage — most of what a social app needs on day one.

Why you'd pick Kotlin instead:

• You're Android-first and don't need iOS at launch.
• Your team already has strong Kotlin/JVM skills.
• The product needs deep OS/background behavior (foreground services, background sync, live/video processing) where native access is much cleaner.

If you later want to share logic while going native on iOS, Kotlin Multiplatform is the bridge — but that's a refinement, not an MVP-branch decision.

One caveat: for a social app, the language is rarely what makes or breaks the MVP. The hard parts are the backend — feed serving, realtime messaging, moderation, and scaling. Budget most of your effort there and pick the frontend your team can iterate fastest on. If time-to-test matters most, I'd go Flutter.

Thank you for recommendation and think' bout Flutter. Can you suggest one more things? On security basis which is most reliable flutter or kotlin?

From a security perspective, neither Flutter nor Kotlin is inherently insecure. The bigger factor is how the application is architected and implemented.

If you're comparing native Android Kotlin vs Flutter, I'd give Kotlin a slight advantage when your priority is Android-specific security and deep platform integration. Kotlin has direct access to Android's security APIs and platform features such as Android Keystore, biometric authentication, secure storage, and permissions.

Flutter can also be very secure, though, and for a cross-platform social-network MVP I'd still choose Flutter if you need Android + iOS from one codebase. You just need to make sure sensitive operations are properly handled through secure platform APIs/native plugins and, most importantly, that your backend/API security is strong.

For a social network, I'd pay particular attention to:
🔐 Secure authentication/session management
🔒 HTTPS/TLS everywhere
🗝️ Secure token/key storage
🛡️ Server-side authorization (never trust the client)
🚫 Input validation and rate limiting
📱 Secure handling of local data
🔎 Dependency and package security
🧑‍💻 Proper backend access controls

So my recommendation would be:
Android-only + maximum native platform control go with Kotlin
Android + iOS + faster MVP development go with Flutter

But don't choose Kotlin just because you think Flutter is less secure. A well-designed Flutter application can be significantly more secure than a poorly designed Kotlin application. 👍
