val recordedActivityUiState = MutableStateFlow(ActivityUiState())
// State used only to update the recordedActivity UI state
val recordedActivityState = activitiesRepository.getRecordedActivity().map { recordedActivity ->
if (recordedActivity != null) {
recordedActivityUiState.update {
ActivityUiState(
id = recordedActivity.id,
title = recordedActivity.title,
note = recordedActivity.note,
startTime = recordedActivity.startTime
)
}
}
}

Gibt es eine Möglichkeit, einen mutablestateFlow mit Daten aus der Datenbank zu initiieren? Ich habe den folgenden Ansatz ausprobiert, aber der RecordedActivityUistate wird nicht mit dem Objekt aus dem ActivitiesRepository .
