Best practices for implementing Flow in Android?

// Example of implementing Flow in Android

import androidx.lifecycle.ViewModel
import androidx.lifecycle.viewModelScope
import kotlinx.coroutines.flow.Flow
import kotlinx.coroutines.flow.collect
import kotlinx.coroutines.flow.flow
import kotlinx.coroutines.launch

class ExampleViewModel : ViewModel() {

    // A simple Flow that emits integers
    private val numberFlow: Flow = flow {
        for (i in 1..5) {
            emit(i) // Emit next number
            kotlinx.coroutines.delay(1000) // Simulate some delay
        }
    }

    fun startFlow() {
        viewModelScope.launch {
            numberFlow.collect { number ->
                // Handle the emitted number
                println("Received number: $number")
            }
        }
    }
}
