when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String userId,
    2. String? displayName,
    3. String domainId,
    4. String domainName,
    5. int topicCount,
    6. double avgMasteryScore,
    7. int topicsAtMastery,
    8. DateTime? lastActive,
    )
)

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 userId,  String? displayName,  String domainId,  String domainName,  int topicCount,  double avgMasteryScore,  int topicsAtMastery,  DateTime? lastActive)  $default,) {final _that = this;
switch (_that) {
case _TeamProgressEntry():
return $default(_that.userId,_that.displayName,_that.domainId,_that.domainName,_that.topicCount,_that.avgMasteryScore,_that.topicsAtMastery,_that.lastActive);case _:
  throw StateError('Unexpected subclass');

}
