whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<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 variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( int activeUsers7d,  int activeUsers30d,  double avgMastery,  int totalSessions7d,  int totalSessions30d,  double assignmentsOnTrackPct,  int assignmentsOverdueCount)?  $default,) {final _that = this;
switch (_that) {
case _OrgAnalyticsSummary() when $default != null:
return $default(_that.activeUsers7d,_that.activeUsers30d,_that.avgMastery,_that.totalSessions7d,_that.totalSessions30d,_that.assignmentsOnTrackPct,_that.assignmentsOverdueCount);case _:
  return null;

}
