mappings property

UnmodifiableMapView<MidiMappingId, MidiMapping> mappings

The mappings that are currently considered to be present.

This is updated optimistically with respect to the back end. When create is called, the mapping is added, assuming that the backend will not error. If there is an error, the mapping is removed.

Implementation

UnmodifiableMapView<MidiMappingId, MidiMapping> get mappings => _mappingsView;
