when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. Sub2ApiAdminDashboardFilter filter,
    2. Sub2ApiAdminUsageGranularity granularity,
    3. String? model,
    4. bool includeStats,
    5. bool includeTrend,
    6. bool includeModelStats,
    7. bool includeGroupStats,
    8. bool includeUsersTrend,
    9. int usersTrendLimit,
    )
)

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 ...;
}
