EventualSingleBuilder class

EventualSingleBuilder provides up to four different builders that are used according to the current state of notifier.

  • If isLoading evaluates to true, then loadingBuilder will be built (if present).
  • If hasError evaluates to true, then errorBuilder will be built (if present).
  • If hasValue evaluates to false, then emptyBuilder will be built (if present).
  • In any other case, builder will be built.
