secondaryOverlay property

  1. @JsonKey(name: 'secondaryOverlay')
String? secondaryOverlay
getter/setter pair

Pulled from the secondary icon, this is the "secondary background" of the secondary icon. Confusing? Sure, that's why I call it "overlay" here: because as far as it's been used thus far, it has been for an optional overlay image. We'll see if that holds up, but at least for now it explains what this image is a bit better.

Implementation

@JsonKey(name:'secondaryOverlay')
String? secondaryOverlay;
