Properties
-
asData
→ AsyncData<
ValueT> ? -
Available on AsyncValue<
Upcast AsyncValue into an AsyncData, or return null if the AsyncValue is an AsyncLoading/AsyncError.ValueT> , provided by the AsyncValueExtensions extensionno setter -
asError
→ AsyncError<
ValueT> ? -
Available on AsyncValue<
Upcast AsyncValue into an AsyncError, or return null if the AsyncValue is an AsyncLoading/AsyncData.ValueT> , provided by the AsyncValueExtensions extensionno setter - error → Object?
-
The error.
no setterinherited
- hasError → bool
-
Available on AsyncValue<
Whether error is not null.ValueT> , provided by the AsyncValueExtensions extensionno setter - hashCode → int
-
The hash code for this object.
no setterinherited
- hasValue → bool
-
Available on AsyncValue<
Whether value is set.ValueT> , provided by the AsyncValueExtensions extensionno setter - isFromCache → bool
-
Available on AsyncValue<
Whether the value was obtained using Riverpod's offline-persistence feature.ValueT> , provided by the AsyncValueExtensions extensionno setter - isLoading → bool
-
Available on AsyncValue<
Whether some new value is currently asynchronously loading.ValueT> , provided by the AsyncValueExtensions extensionno setter - isRefreshing → bool
-
Available on AsyncValue<
Whether the associated provider was forced to recompute even though none of its dependencies has changed, after at least one value/error was emitted.ValueT> , provided by the AsyncValueExtensions extensionno setter - isReloading → bool
-
Available on AsyncValue<
Whether the associated provider was recomputed because of a dependency change (using Ref.watch), after at least one value/error was emitted.ValueT> , provided by the AsyncValueExtensions extensionno setter - progress → num?
-
Available on AsyncValue<
The current progress of the asynchronous operation.ValueT> , provided by the AsyncValueExtensions extensionno setter - requireValue → ValueT
-
If hasValue is true, returns the value.
Otherwise if hasError, rethrows the error.
Finally if in loading state, throws a StateError.
no setterinherited
- retrying → bool
-
Available on AsyncValue<
If an error was emitted, whether that error is currently being retried.ValueT> , provided by the AsyncValueExtensions extensionno setter - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- stackTrace → StackTrace?
-
The stacktrace of error.
no setterinherited
- value → ValueT?
-
The value currently exposed.

whenData<
NewT> (NewT cb(ValueT value)) → AsyncValue< NewT> -
Available on AsyncValue<
Shorthand for when to handle only theValueT> , provided by the AsyncValueExtensions extensiondata
