fromJson static method

SystemMetaDataEncrypted? fromJson(dynamic value)

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

Implementation

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

    return SystemMetaDataEncrypted(
      secretForeignKeys: json[r'secretForeignKeys'] == null ? const [] : (json[r'secretForeignKeys'] as List).cast<String>(),
      cryptedForeignKeys: json[r'cryptedForeignKeys'] == null ? const {} : Delegation.mapListFromJson(json[r'cryptedForeignKeys']),
      delegations: json[r'delegations'] == null ? const {} : Delegation.mapListFromJson(json[r'delegations']),
