State Management

Using by keyword

To use the by keyword in compose, import:

import androidx.compose.runtime.getValue
import androidx.compose.runtime.setValue

Manual Recompose

var count by remember { mutableStateOf(0) }
key(count){
    // recompose when the var count change
}

snapshotFlow

Kind of like LaunchedEffect but allows use in non-composable functions

snapshotFlow { searchQuery }
    .filter { it.length > 2 } // Only emit if query is longer than 2 characters
    .debounce(500) // Wait 500ms after last change
    .collect { query ->
        println("Search query: $query")
        // Example: Trigger a network search
    }
