when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String jobId,
    3. String did,
    4. @JobStatusStateConverter() JobStatusState state,
    5. int? progress,
    6. @BlobConverter() Blob? blob,
    7. String? error,
    8. String? message,
    9. Map<String, dynamic>? $unknown,
    )
)

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( String $type,  String jobId,  String did, @JobStatusStateConverter()  JobStatusState state,  int? progress, @BlobConverter()  Blob? blob,  String? error,  String? message,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _JobStatus():
return $default(_that.$type,_that.jobId,_that.did,_that.state,_that.progress,_that.blob,_that.error,_that.message,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
