multiple_result

Bug Fixes

• Error.getOrThrow() now correctly passes <S, E> to SuccessResultNotFoundException, so toString() shows the actual types instead of dynamic.

New Features

• Result.tryCatch(action, onError) — static factory that wraps a potentially-throwing synchronous computation.
• getOrElse(orElse) — returns the success value or a fallback computed from the error.
• onSuccess(action) / onError(action) — side-effect tap methods that execute an action without transforming the result, returning this for chaining.
• flatMapError(mapper) — symmetric counterpart to flatMap for the error channel.
• recover(mapper) — alias for flatMapError.
• swap() — converts Success to Error and vice versa.
• AsyncResult<S, E> — zero-cost Future<Result<S, E>> wrapper via Dart extension types, with a full mirrored API (mapSuccess, mapError, map, flatMap, flatMapAsync, flatMapError, swap, onSuccess, onError, getOrThrow, getOrElse, tryGetSuccess, tryGetError, when, isSuccess, isError, and tryCatch).
• AsyncResultOf<S, E> typedef alias for AsyncResult<S, E>.
