whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String originalText,
    2. String translatedText,
    3. String originalLanguageCode,
    4. String translatedLanguageCode,
    5. bool isApproved,
    6. DateTime createdAt,
    7. DateTime updatedAt,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( String originalText,  String translatedText,  String originalLanguageCode,  String translatedLanguageCode,  bool isApproved,  DateTime createdAt,  DateTime updatedAt)?  $default,) {final _that = this;
switch (_that) {
case _TranslationResponse() when $default != null:
return $default(_that.originalText,_that.translatedText,_that.originalLanguageCode,_that.translatedLanguageCode,_that.isApproved,_that.createdAt,_that.updatedAt);case _:
  return null;

}
}
