Hey fellow devs 👋

I wanted to share our latest deep dive (Dec 2024) on Jetpack Compose composition patterns.

Here’s a common challenge we tackle—handling UI variations without ending up in **“if-else hell”**:

kotlin // The problematic way - "if-else hell"  Composable  fun UserProfile(...) { Column(...) { // Strong coupling between components if (isSelf) { ... } if (isPremiumMember) { ... } if (shouldShowEmail) { ... } else { ... } } }

A Better Approach: Compound Component Pattern

Composable  fun UserProfile( user: User, content:  Composable  UserProfileScope.() -> Unit, ) { val scope = remember { DefaultUserProfileScope(user) } Column { // Common UI elements ProfileImage() Name() // Flexible content area with shared state scope.content() } } // Usage - Mix and match components as needed  Composable  fun SelfProfile(user: User) { UserProfile(user) { Bio() EditButtons() } }

The article dives deep into two patterns we’ve found particularly useful:

• Slot pattern (like Material’s TopAppBar)
• Compound Component pattern (sharing state through scope)

We’ve used these extensively in our Video SDK ( ) for flexible UI customization. But perhaps most interestingly, we found that sometimes a bit of duplication is better than forcing reuse through complex patterns.

Would love to hear your thoughts.

How do you handle component reuse vs. separation in your Compose projects?
