when<TResult extends Object?> method
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 plan, String source, DateTime? expiresAt, DateTime? trialExpiresAt, DateTime? trialStartedAt, Map<String, dynamic> entitlements, List<String> grantsApplied, EntitlementAiModel ai) $default,) {final _that = this;
switch (_that) {
case _EntitlementModel():
return $default(_that.plan,_that.source,_that.expiresAt,_that.trialExpiresAt,_that.trialStartedAt,_that.entitlements,_that.grantsApplied,_that.ai);case _:
throw StateError('Unexpected subclass');
}
}
