AsyncError<T> class

Creates an AsyncValue in the error state.

I don't have a StackTrace, what can I do? You can still construct an AsyncError by passing StackTrace.current:

AsyncValue.error(error, StackTrace.current);

Constructors

AsyncError(Object error, StackTrace stackTrace)
Creates an AsyncValue in the error state.

Properties

asData → AsyncData<T>?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Upcast AsyncValue into an AsyncData, or return null if the AsyncValue is an AsyncLoading/AsyncError.
no setter
asError → AsyncError<T>?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Upcast AsyncValue into an AsyncError, or return null if the AsyncValue is an AsyncLoading/AsyncData.
no setter
error → Object
The error.
final
hasError → bool

Available on AsyncValue<T>, provided by the AsyncValueX extension

Whether error is not null.
no setter
hashCode → int
The hash code for this object.
no setterinherited
hasValue → bool
Whether value is set.
final
isLoading → bool
Whether some new value is currently asynchronously loading.
final
isRefreshing → bool

Available on AsyncValue<T>, provided by the AsyncValueX extension

Whether the associated provider was forced to recompute even though none of its dependencies has changed, after at least one value/error was emitted.
no setter
isReloading → bool

Available on AsyncValue<T>, provided by the AsyncValueX extension

Whether the associated provider was recomputed because of a dependency change (using Ref.watch), after at least one value/error was emitted.
no setter
requireValue → T

Available on AsyncValue<T>, provided by the AsyncValueX extension

If hasValue is true, returns the value. Otherwise if hasError, rethrows the error. Finally if in loading state, throws a StateError.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stackTrace → StackTrace
The stacktrace of error.
final
value → T?
The value currently exposed.
no setteroverride
valueOrNull → T?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Return the value or previous value if in loading/error state.
no setter

Methods

copyWithPrevious(AsyncValue<T> previous, {bool isRefresh = true}) → AsyncError<T>
Clone an AsyncValue, merging it with previous.
override
map<R>({required R data(AsyncData<T> data), required R error(AsyncError<T> error), required R loading(AsyncLoading<T> loading)}) → R
Perform some action based on the current state of the AsyncValue.
override
mapOrNull<R>({R? data(AsyncData<T> data)?, R? error(AsyncError<T> error)?, R? loading(AsyncLoading<T> loading)?}) → R?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform some actions based on the state of the AsyncValue, or return null if the current state wasn't tested.
maybeMap<R>({R data(AsyncData<T> data)?, R error(AsyncError<T> error)?, R loading(AsyncLoading<T> loading)?, required R orElse()}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform some actions based on the state of the AsyncValue, or call orElse if the current state was not tested.
maybeWhen<R>({bool skipLoadingOnReload = false, bool skipLoadingOnRefresh = true, bool skipError = false, R data(T data)?, R error(Object error, StackTrace stackTrace)?, R loading()?, required R orElse()}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Switch-case over the state of the AsyncValue while purposefully not handling some cases.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
unwrapPrevious() → AsyncValue<T>
The opposite of copyWithPrevious, reverting to the raw AsyncValue with no information on the previous state.
inherited
when<R>({bool skipLoadingOnReload = false, bool skipLoadingOnRefresh = true, bool skipError = false, required R data(T data), required R error(Object error, StackTrace stackTrace), required R loading()}) → R

Available on AsyncValue<T>, provided by the AsyncValueX extension

Performs an action based on the state of the AsyncValue.
whenData<R>(R cb(T value)) → AsyncValue<R>

Available on AsyncValue<T>, provided by the AsyncValueX extension

Shorthand for when to handle only the data case.
whenOrNull<R>({bool skipLoadingOnReload = false, bool skipLoadingOnRefresh = true, bool skipError = false, R? data(T data)?, R? error(Object error, StackTrace stackTrace)?, R? loading()?}) → R?

Available on AsyncValue<T>, provided by the AsyncValueX extension

Perform actions conditionally based on the state of the AsyncValue.

Operators

operator ==(Object other) → bool
The equality operator.
