maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({ TResult bytes(double value)?, TResult kb(double value)?, TResult mb(double value)?, TResult gb(double value)?, TResult tb(double value)?, 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( double value)?  bytes,TResult Function( double value)?  kb,TResult Function( double value)?  mb,TResult Function( double value)?  gb,TResult Function( double value)?  tb,required TResult orElse(),}) {final _that = this;
switch (_that) {
case BytesModel() when bytes != null:
return bytes(_that.value);case KbModel() when kb != null:
return kb(_that.value);case MbModel() when mb != null:
return mb(_that.value);case GbModel() when gb != null:
return gb(_that.value);case TbModel() when tb != null:
return tb(_that.value);case _:
  return orElse();
