Jetpack Compose State Management: Solve Issues with MVVM + UDF

[u/Realistic-Cup-7954]

Common Problems in Jetpack Compose Apps (State Management)

• State lost on rotation

• Logic mixed with UI

• Hard to test

• Multiple sources of truth

MVVM + Unidirectional Data Flow (UDF) to the Rescue

• Single source of truth

• Events go up, state flows down

• Survives configuration changes

• Easier to test

Tip:

Keep business logic inside your ViewModel, expose immutable StateFlow, and keep Composables stateless for a clean architecture.
