The process of emitting a flow value from a separate function in Kotlin Coroutines involves the following steps:
Create a flow object using the flow builder function.
Use the emit() function to emit values from the flow object.
Create a separate function that returns the flow object.
Call the function and collect the emitted values using the collect() function.
For example, consider the following code:
fun myFlow(): Flow<Int> = flow {
for (i in 1..10) {
emit(i)
}
}
fun main() {
runBlocking {
myFlow().collect {
println(it)
}
}
}
In this example, the myFlow() function creates a flow object that emits values from 1 to 10 using the emit() function. The main() function calls the myFlow() function and collects the emitted values using the collect() function. The output will be the values 1 to 10 printed to the console.
