isNotOptional property

@Deprecated('Use isRequired instead') bool get isNotOptional

Return true if this parameter is a required parameter. Required parameters are always positional, unless the experiment 'non-nullable' is enabled, in which case named parameters can also be required.

Note: regardless of the state of the 'non-nullable' experiment, the presence or absence of the @required annotation does not change the meaning of this getter. The parameter {@required int x} will return false and the parameter {@required required int x} will return true

Implementation
