when<TResult extends Object?> method
- @optionalTypeArgs
A switch-like method, using callbacks.
As opposed to map, this offers destructuring.
It is equivalent to doing:
switch (sealedClass) {
case Subclass(:final field):
return ...;
case Subclass2(:final field2):
return ...;
}
Implementation
@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( int sizeBytes, String mimeType, String? name, int? durationMs, int? width, int? height, Map<String, dynamic>? $unknown) $default,) {final _that = this;
switch (_that) {
case _VideoStartUploadInput():
return $default(_that.sizeBytes,_that.mimeType,_that.name,_that.durationMs,_that.width,_that.height,_that.$unknown);case _:
throw StateError('Unexpected subclass');
}
}
