when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. PlanTier plan,
    2. EntitlementSource source,
    3. DateTime? expiresAt,
    4. DateTime? trialExpiresAt,
    5. DateTime? trialStartedAt,
    6. Map<String, dynamic> entitlements,
    7. List<String> grantsApplied,

    9. int? aiWeeklyCap,
    10. int? aiTotalCap,
    11. int aiBoost,
    )
)

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( PlanTier plan,  EntitlementSource source,  DateTime? expiresAt,  DateTime? trialExpiresAt,  DateTime? trialStartedAt,  Map<String, dynamic> entitlements,  List<String> grantsApplied,  int? aiDailyCap,  int? aiWeeklyCap,  int? aiTotalCap,  int aiBoost)  $default,) {final _that = this;
switch (_that) {
case _Entitlement():
return $default(_that.plan,_that.source,_that.expiresAt,_that.trialExpiresAt,_that.trialStartedAt,_that.entitlements,_that.grantsApplied,_that.aiDailyCap,_that.aiWeeklyCap,_that.aiTotalCap,_that.aiBoost);case _:
  throw StateError('Unexpected subclass');
