maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult resultAvailable(
    1. ResultAvailable data
    )?,
  2. TResult resultUnavailable(
    1. ResultUnavailable data
    )?,
  3. TResult unknown(
    1. Map<String, dynamic> data
    )?,
  4. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({TResult Function( ResultAvailable data)?  resultAvailable,TResult Function( ResultUnavailable data)?  resultUnavailable,TResult Function( Map<String, dynamic> data)?  unknown,required TResult orElse(),}) {final _that = this;
switch (_that) {
case UTempCheckHandleAvailabilityResultResultAvailable() when resultAvailable != null:
return resultAvailable(_that.data);case UTempCheckHandleAvailabilityResultResultUnavailable() when resultUnavailable != null:
return resultUnavailable(_that.data);case UTempCheckHandleAvailabilityResultUnknown() when unknown != null:
return unknown(_that.data);case _:
  return orElse();

}
