fromJson static method

Session? fromJson(dynamic value)

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

Implementation

// ignore: prefer_constructors_over_static_methods
static Session? 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(() {
      assert(json.containsKey(r'id'), 'Required key "Session[id]" is missing from JSON.');
      assert(json[r'id'] != null, 'Required key "Session[id]" has a null value in JSON.');
      return true;
    }());

    return Session(
      id: mapValueOfType<String>(json, r'id')!,
      ipAddress: mapValueOfType<String>(json, r'ipAddress'),
      userAgent: mapValueOfType<String>(json, r'userAgent'),
      deviceType: mapValueOfType<String>(json, r'deviceType'),
      browser: mapValueOfType<String>(json, r'browser'),
      os: mapValueOfType<String>(json, r'os'),
      country: mapValueOfType<String>(json, r'country'),

      createdAt: mapDateTime(json, r'createdAt', r''),
      lastActiveAt: mapDateTime(json, r'lastActiveAt', r''),
      isCurrent: mapValueOfType<bool>(json, r'isCurrent'),
