DisplayState({required bool online, DisplayPower? power, DisplayShutter? shutter, bool? signal, double? temperatureC, TestPattern? pattern, String? lastSeen, List<DisplayCapability>? capabilities, List<DisplayFault>? faults, Map<String, Object?> extra = const {}})

Creates a DisplayState.

const

DisplayState.fromJson(Map<String, Object?> json, [String path = ''])

Methods

copyWith({bool? online, DisplayPower? power, DisplayShutter? shutter, bool? signal, double? temperatureC, TestPattern? pattern, String? lastSeen, List<DisplayCapability>? capabilities, List<DisplayFault>? faults, Map<String, Object?>? extra}) → DisplayState

A copy with the given members replaced (a member cannot be reset to null this way).

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, Object?>
