fromMap static method

Position fromMap(dynamic message)

Converts the supplied Map to an instance of the Position class.

Implementation

static Position fromMap(dynamic message) {
  final Map<dynamic, dynamic> positionMap = message;

  if (!positionMap.containsKey('latitude')) {
    throw ArgumentError.value(positionMap, 'positionMap',
        'The supplied map doesn\'t contain the mandatory key `latitude`.');
  }

  if (!positionMap.containsKey('longitude')) {
    throw ArgumentError.value(positionMap, 'positionMap',
        'The supplied map doesn\'t contain the mandatory key `longitude`.');
  }

  final timestamp = positionMap['timestamp'] != null
      ? DateTime.fromMillisecondsSinceEpoch(positionMap['timestamp'].toInt(),
          isUtc: true)
      : null;

  return Position(
    latitude: positionMap['latitude'],
    longitude: positionMap['longitude'],
    timestamp: timestamp,
    altitude: positionMap['altitude'] ?? 0.0,
    accuracy: positionMap['accuracy'] ?? 0.0,
    heading: positionMap['heading'] ?? 0.0,
    floor: positionMap['floor'],
    speed: positionMap['speed'] ?? 0.0,
    speedAccuracy: positionMap['speed_accuracy'] ?? 0.0,
    isMocked: positionMap['is_mocked'] ?? false,
  );
