maybeMap<TResult extends Object?> method

TResult maybeMap<TResult extends Object?>({

    1. UModerationCauseBlocking value
    )?,
  2. TResult blockedBy(
    1. UModerationCauseBlockedBy value

    )?,
  7. TResult hidden(
    1. UModerationCauseHidden value
    )?,
  8. required TResult orElse(),
})

A variant of map that fallback to returning orElse.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({TResult Function( UModerationCauseBlocking value)?  blocking,TResult Function( UModerationCauseBlockedBy value)?  blockedBy,TResult Function( UModerationCauseBlockOther value)?  blockOther,TResult Function( UModerationCauseLabel value)?  label,TResult Function( UModerationCauseMuted value)?  muted,TResult Function( UModerationCauseMuteWord value)?  muteWord,TResult Function( UModerationCauseHidden value)?  hidden,required TResult orElse(),}){
final _that = this;
switch (_that) {
case UModerationCauseBlocking() when blocking != null:
return blocking(_that);case UModerationCauseBlockedBy() when blockedBy != null:
