isNotOptional property Null safety

bool 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, this will return false for a named parameter that is annotated with the @required annotation.

Implementation

// TODO(brianwilkerson) Rename this to `isRequired`.
bool get isNotOptional;
