whenOrNull<TResult extends Object?> method
- @optionalTypeArgs
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? base, String? complete, String? empty, String? focus, String? invalid, bool? webkitAutofill)? $default,) {final _that = this;
switch (_that) {
case _CardElementClasses() when $default != null:
return $default(_that.base,_that.complete,_that.empty,_that.focus,_that.invalid,_that.webkitAutofill);case _:
return null;
}
}
