fromJson static method

UserNotificationCount? fromJson(dynamic value)

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

Implementation

// ignore: prefer_constructors_over_static_methods
static UserNotificationCount? 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(json[r'_id'] != null, 'Required key "UserNotificationCount[_id]" has a null value in JSON.');
