unknownEnumValue property Null safety

Enum? unknownEnumValue
final

The value to use for an enum field when the value provided is not in the source enum.

Valid only on enum fields with a compatible enum value.

If you want to use the value null when encountering an unknown value, use the value of JsonKey.nullForUndefinedEnumValue instead. This is only valid on a nullable enum field.

Implementation

final Enum? unknownEnumValue;
