DisplayFeature class Null safety

Area of the display that may be obstructed by a hardware feature.

This is populated only on Android.

The bounds are measured in logical pixels. On devices with two screens the coordinate system starts with 0,0 in the top-left corner of the left or top screen and expands to include both screens and the visual space between them.

The type describes the behaviour and if DisplayFeature obstructs the display. For example, DisplayFeatureType.hinge and DisplayFeatureType.cutout both obstruct the display, while DisplayFeatureType.fold does not.

Device with a hinge display feature

Device with a fold display feature

Device with a cutout display feature

The state contains information about the posture for foldable features (DisplayFeatureType.hinge and DisplayFeatureType.fold). The posture is the shape of the display, for example DisplayFeatureState.postureFlat or DisplayFeatureState.postureHalfOpened. For DisplayFeatureType.cutout, the state is not used and has the DisplayFeatureState.unknown value.
