Success class - stream_feed library

Properties

data → T: The T data associated with the result.
final
hashCode → int: The hash code for this object.
no setterinherited
isFailure → bool: Returns true if this instance represents a failed outcome. In this case isSuccess returns false.
no setterinherited
isSuccess → bool: Returns true if this instance represents a successful outcome. In this case isFailure returns false.
no setterinherited
props → List<Object?>: The list of properties that will be used to determine whether two instances are equal.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
stringify → bool?: If set to true, the toString method will be overridden to output this instance's props.
no setterinherited

Methods

exceptionOrNull() → Object?: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated Object error if this instance represents Failure or null if it is Success.
flatMap<R>(Result<R> transform(T value)) → Result<R>: Available on Result<T>, provided by the PatternMatching extension
Transforms this Result<T> to Result<R> by applying transform if this is a Success, or returns the Failure unchanged if this is a Failure.
flatMapAsync<R>(Future<Result<R>> transform(T value)) → Future<Result<R>>: Available on Result<T>, provided by the PatternMatching extension
Asynchronously transforms this Result<T> to Result<R> by applying transform if this is a Success, or returns the Failure unchanged if this is a Failure.
flatten<R>() → Result<R>: Available on Result<T>, provided by the PatternMatching extension
Flattens a nested Result of Result to a single Result. Only works when T is of type Result<R>.
fold<R>({required R onSuccess(T value), required R onFailure(Object error, StackTrace? stackTrace)}) → R: Available on Result<T>, provided by the PatternMatching extension
Returns the result of onSuccess for the encapsulated value if this instance represents Success or the result of onFailure function for the encapsulated error if it is Failure.
getOrDefault<R>(R defaultValue) → R: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated value if this instance represents Success or the defaultValue if it is Failure.
getOrElse<R>(R onFailure(Object error, StackTrace? stackTrace)) → R: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated value if this instance represents Success or the result of onFailure function for the encapsulated error if it is Failure.
getOrNull() → T?: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated value if this instance represents Success or null if it is Failure.
getOrThrow() → T: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated value if this instance represents Success or throws the encapsulated error if it is Failure.
map<R>(R transform(T value)) → Result<R>: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated result of the given transform function applied to the encapsulated value if this instance represents Success or the original encapsulated error if it is Failure.
mapAsync<R>(Future<R> transform(T value)) → Future<Result<R>>: Available on Result<T>, provided by the PatternMatching extension
Asynchronously returns the encapsulated result of the given transform function applied to the encapsulated value if this instance represents Success or the original encapsulated error if it is Failure.
mapCatching<R>(R transform(T value)) → Result<R>: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated result of the given transform function applied to the encapsulated value if this instance represents Success or the original encapsulated error if it is Failure.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

onFailure(void action(Object error, StackTrace? stackTrace)) → Result<T>: Available on Result<T>, provided by the PatternMatching extension
Performs the given action on the encapsulated error if this instance represents Failure. Returns the original Result unchanged.
onSuccess(void action(T value)) → Result<T>: Available on Result<T>, provided by the PatternMatching extension
Performs the given action on the encapsulated value if this instance represents Success. Returns the original Result unchanged.
recover<R>(R transform(Object error, StackTrace? stackTrace)) → Result<R>: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated result of the given transform function applied to the encapsulated error if this instance represents Failure or the original encapsulated value if it is Success.
recoverCatching<R>(R transform(Object error, StackTrace? stackTrace)) → Result<R>: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated result of the given transform function applied to the encapsulated error if this instance represents Failure or the original encapsulated value if it is Success.
stackTraceOrNull() → StackTrace?: Available on Result<T>, provided by the PatternMatching extension
Returns the encapsulated StackTrace if this instance represents Failure or null if it is Success.
toString() → String: A string representation of this object.
