when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. int activeUsers7d,
    2. int activeUsers30d,
    3. double avgMastery,
    4. int totalSessions7d,
    5. int totalSessions30d,
    6. double assignmentsOnTrackPct,
    7. int assignmentsOverdueCount,
    )
)

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(@JsonKey(name: 'active_users_7d')  int activeUsers7d, @JsonKey(name: 'active_users_30d')  int activeUsers30d,  double avgMastery, @JsonKey(name: 'total_sessions_7d')  int totalSessions7d, @JsonKey(name: 'total_sessions_30d')  int totalSessions30d,  double assignmentsOnTrackPct,  int assignmentsOverdueCount)  $default,) {final _that = this;
switch (_that) {
case _OrgAnalyticsSummaryModel():
return $default(_that.activeUsers7d,_that.activeUsers30d,_that.avgMastery,_that.totalSessions7d,_that.totalSessions30d,_that.assignmentsOnTrackPct,_that.assignmentsOverdueCount);case _:
  throw StateError('Unexpected subclass');
