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? access, String? error, LogLevel? loglevel, bool? dnsLog, String? maskAddress)? $default,) {final _that = this;
switch (_that) {
case _LogConfig() when $default != null:
return $default(_that.access,_that.error,_that.loglevel,_that.dnsLog,_that.maskAddress);case _:
return null;
}
}
