FtrResultExt<S, E> extension

Extension methods for FtrResult to provide convenient asynchronous operations. This extension allows chaining operations on Future

on

• FtrResult<S, E>

Properties

isError → Future<bool>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously checks if this result represents an error.

no setter

isSuccess → Future<bool>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously checks if this result represents a success.

no setter

Methods

execute() → Future<void>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously forces evaluation of the result without returning any value.

flat() → Future<(S?, E?)>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously flattens the result into a tuple.

getOrNull() → Future<S?>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously extracts the success value or returns null if the result is an error.

getOrThrow() → Future<S>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously extracts the success value or throws an exception if the result is an error.

mapError<E2>(E2 mapper(E err)) → FtrResult<S, E2>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously transforms the error value using a simple mapper function.

mapOnError<E2>(FutureOr<Result<S, E2>> mapper(E err)) → FtrResult<S, E2>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously transforms the error value using a mapper that returns a Result.

mapOnSuccess<S2>(FutureOr<Result<S2, E>> mapper(S data)) → FtrResult<S2, E>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously transforms the success value using a mapper that returns a Result.

mapSuccess<S2>(S2 mapper(S data)) → FtrResult<S2, E>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously transforms the success value using a simple mapper function.

nullable() → FtrResult<S?, E>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously converts the result to allow nullable success values.

onError(void onError(E error)) → FtrResult<S, E>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously executes a side effect if the result is an error.

onSuccess(void onSuccess(S data)) → FtrResult<S, E>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously executes a side effect if the result is successful.

resolve({required S onError(E error)}) → Future<Success<S, E>>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously converts any error result into a successful result.

when<T>({required T success(S data), required T error(E error)}) → Future<T>

Available on FtrResult<S, E>, provided by the FtrResultExt extension

Asynchronously pattern matches on the result and executes the appropriate callback.
