fromJson static method

Device? fromJson(dynamic value)

Returns a new Device instance and imports its values from value if it's a Map, null otherwise.

Implementation

// ignore: prefer_constructors_over_static_methods
static Device? fromJson(dynamic value) {
  if (value is Map) {
    final json = value.cast<String, dynamic>();

    // Ensure that the map contains the required keys.
    // Note 1: the values aren't checked for validity beyond being non-null.
    // Note 2: this code is stripped in release mode!
    assert(() {
      for (var key in requiredKeys) {
        assert(json.containsKey(key),
            'Required key "Device[$key]" is missing from JSON.');
        assert(json[key] != null,
            'Required key "Device[$key]" has a null value in JSON.');
      }
      return true;
    }());

    return Device(
      name: mapValueOfType<String>(json, r'name'),
      deviceId: mapValueOfType<String>(json, r'deviceId')!,
      availability: DeviceAvailability.listFromJson(json[r'availability'])!,
      ip: mapValueOfType<String>(json, r'ip'),
      owned: mapValueOfType<bool>(json, r'owned')!,
      configured: mapValueOfType<bool>(json, r'configured')!,
