toSet method
Returns a set of all of the cards in this collection.
This method is provided as a convenience, but is not guaranteed to be
cheap to compute. For use in a hot loop, or in a UI (i.e. Flutter
build()
methods), it's highly recommended to use the methods on this
class instead, or cache the result of this method.
Implementation
@useResult
Set<Card> toSet() => allCards.toSet();
