Methods

combine<R2>(Either<L, R2> other) → Either<L, (R, R2)>

inherited

doOnLeft(void block(L v)) → Either<L, R>

Available on Either<L, R>, provided by the DoEither extension

Performs a side-effect by running block function if the value is left and returns the same Either.

doOnLeftAsync(FutureOr<void> block(L v)) → AsyncEither<L, R>

Available on Either<L, R>, provided by the EitherAsync extension

doOnRight(void block(R v)) → Either<L, R>

Available on Either<L, R>, provided by the DoEither extension

Performs a side-effect by running block function if the value is right and returns the same Either.

doOnRightAsync(FutureOr<void> block(R v)) → AsyncEither<L, R>

Available on Either<L, R>, provided by the EitherAsync extension

flatMap<T>(Either<L, T> f(R)) → Either<L, T>

override

flatMapAsync<T>(FutureOr<Either<L, T>> f(R)) → AsyncEither<L, T>

Available on Either<L, R>, provided by the EitherAsync extension

flatMapLeftAsync<T>(FutureOr<Either<T, R>> f(L)) → Future<Either<T, R>>

Available on Either<L, R>, provided by the EitherAsync extension

inherited

map<T>(T f(R)) → Either<L, T>

override

mapAsync<T>(FutureOr<T> f(R)) → AsyncEither<L, T>

Available on Either<L, R>, provided by the EitherAsync extension

mapLeft<L1>(L1 f(L)) → Either<L1, R>

inherited

mapLeftAsync<T>(FutureOr<T> f(L)) → Future<Either<T, R>>

Available on Either<L, R>, provided by the EitherAsync extension
