DisplayFeatureType enum Null safety

Type of DisplayFeature, describing the DisplayFeature behaviour and if it obstructs the display.

Some types of DisplayFeature, like DisplayFeatureType.fold, can be reported without actually impeding drawing on the screen. They are useful for knowing where the display is bent or has a crease. The DisplayFeature.bounds can be 0-width in such cases.

The shape formed by the screens for types DisplayFeatureType.fold and DisplayFeatureType.hinge is called the posture and is exposed in DisplayFeature.state. For example, the DisplayFeatureState.postureFlat posture means the screens form a flat surface, while DisplayFeatureState.postureFlipped posture means the screens are facing opposite directions.
