mapOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? mapOrNull<TResult extends Object?>({
  1. TResult? mode(
    1. CreateAssistantRequestResponseFormatEnumeration value
    )?,
  2. TResult? responseFormat(
    1. CreateAssistantRequestResponseFormatResponseFormat value
    )?,
})

A variant of map that fallback to returning null.

It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs
TResult? mapOrNull<TResult extends Object?>({
  TResult? Function(CreateAssistantRequestResponseFormatEnumeration value)?
      mode,
  TResult? Function(CreateAssistantRequestResponseFormatResponseFormat value)?
      responseFormat,
}) {
  final _that = this;
  switch (_that) {
    case CreateAssistantRequestResponseFormatEnumeration() when mode != null:
      return mode(_that);
    case CreateAssistantRequestResponseFormatResponseFormat()
        when responseFormat != null:
      return responseFormat(_that);
    case _:
      return null;
  }
}
