whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String? name,
    3. String? lang,
    4. String? contentMarkdown,
    5. String? subject,
    6. String? updatedBy,
    7. bool? disabled,
    8. Map<String, dynamic>? $unknown,
    )?
)

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 id,  String? name,  String? lang,  String? contentMarkdown,  String? subject,  String? updatedBy,  bool? disabled,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _CommunicationUpdateTemplateInput() when $default != null:
return $default(_that.id,_that.name,_that.lang,_that.contentMarkdown,_that.subject,_that.updatedBy,_that.disabled,_that.$unknown);case _:
  return null;

}
}
