How to use the @react-native-firebase/app/lib/common.isDate function in @react-native-firebase/app

if (isArray(value)) {
    return getTypeMapInt('array', buildNativeArray(value));
  }

  if (isObject(value)) {
    if (value instanceof FirestoreDocumentReference) {
      return getTypeMapInt('reference', value.path);
    }

    if (value instanceof FirestoreGeoPoint) {
      return getTypeMapInt('geopoint', [value.latitude, value.longitude]);
    }

    // Handle Date objects are Timestamps as per web sdk
    if (isDate(value)) {
      const timestamp = FirestoreTimestamp.fromDate(value);
      return getTypeMapInt('timestamp', [timestamp.seconds, timestamp.nanoseconds]);
    }

    if (value instanceof FirestoreTimestamp) {
      return getTypeMapInt('timestamp', [value.seconds, value.nanoseconds]);
    }

    if (value instanceof FirestoreBlob) {
      return getTypeMapInt('blob', value.toBase64());
    }

    if (value instanceof FirestoreFieldValue) {
      return getTypeMapInt('fieldvalue', [value._type, value._elements]);
    }

static fromDate(date) {
    if (!isDate(date)) {
      throw new Error(
        "firebase.firestore.Timestamp.fromDate(*) 'date' expected a valid Date object.",
      );
    }

    return FirestoreTimestamp.fromMillis(date.getTime());
  }
