when<R> method

R when<R>({
  1. required R data(
    1. T data
  2. required R error(
    1. Object error,
    2. StackTrace? stackTrace
  3. required R loading(),

Performs an action based on the state of the AsyncValue.

All cases are required, which allows returning a non-nullable value.


R when<R>({
  required R Function(T data) data,
  required R Function(Object error, StackTrace? stackTrace) error,
  required R Function() loading,
}) {
  return _map(
    data: (d) => data(d.value),
    error: (e) => error(e.error, e.stackTrace),
    loading: (l) => loading(),
