I have two data sources which I want to combine ```private val workouts = flow emit userRepository getWorkouts private val exercises = flow emit userRepository getExercises val workoutsByExerciseId Flow lt Map lt String Workout gt gt = do some transformation which combines both sources``` I want to create `workoutsByExerciseId` which should depend on both `workouts` and `exercises` If either source changes `workoutsByExerciseId` should always re emit with the latest data Which flow operator do I need here

I have two data sources which I want to combine ```private v kotlinlang #flow

I have two data sources which I want to combine:

private val workouts = flow { emit(userRepository.getWorkouts()) }
private val exercises = flow { emit(userRepository.getExercises()) }

val workoutsByExerciseId: Flow<Map<String, Workout>> = ? // do some transformation which combines both sources

I want to create

workoutsByExerciseId

which should depend on both

workouts

exercises

. If either source changes,

workoutsByExerciseId

should always re-emit with the latest data. Which flow operator do I need here?
