Using State in Jetpack Compose for Reactive UI

In Jetpack Compose, managing UI state efficiently is crucial for creating responsive applications. By leveraging the state management capabilities of Compose, you can ensure that your UI updates automatically when the underlying data changes. A common practice is to use remember and mutableStateOf to hold the state of your composables. This allows your UI to react to changes without the need for complex lifecycle management.

import androidx.compose.runtime.Composable
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.material.Text
import androidx.compose.material.Button

@Composable
fun Counter() {
    val count = remember { mutableStateOf(0) }

    Button(onClick = { count.value++ }) {
        Text(text = "Count: ${count.value}")
    }
}
