ParallelWaitError class - dart:async library (original) (raw)
Error thrown when waiting for multiple futures, when some have errors.
The V and E types will have the same basic shape as the original collection of futures that was waited on.
For example, if the original awaited futures were a record(Future<T1>, ..., Future<Tn>), the type V will be (T1?, ..., Tn?) which allows keeping the values of futures that completed with a value, and E will be (AsyncError?, ..., AsyncError?), also with _n_fields, which can contain the errors for the futures which completed with an error.
Waiting for a list or iterable of futures should provide a list of nullable values and errors of the same length.
