Properties
-
allTransitiveDependencies
→ Iterable<
ProviderOrFamily> ? -
All the dependencies of a provider and their dependencies too.
finalinherited
- argument → Object?
-
If this provider was created with the
.family
modifier, argument is the variable that was used.final - debugGetCreateSourceHash → DebugGetCreateSourceHash?
-
A debug-only fucntion for obtaining a hash of the source code of the
initialization function.
final
-
dependencies
→ Iterable<
ProviderOrFamily> ? -
The list of providers that this provider potentially depends on.
finalinherited
-
from
→ Family<
Object?> ? -
If this provider was created with the
.family
modifier, from is the.family
instance.final - hashCode → int
-
The hash code for this object.

- name → String?
-
A custom label for providers.

Methods
-
addListener(
Node node, void listener(StateT? previous, StateT next), {required void onError(Object error, StackTrace stackTrace)?, required void onDependencyMayHaveChanged()?, required bool fireImmediately}) → ProviderSubscription< StateT> -
Starts listening to this transformer
override
-
createElement(
) → ProviderElementBase< StateT> - An internal method that defines how a provider behaves.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
read(
Node node) → StateT -
Obtains the result of this provider expression without adding listener.
override
-
select<
Selected> (Selected selector(StateT value)) → ProviderListenable< Selected> -
Partially listen to a provider.
inherited
-
toString(
) → String -
A string representation of this object.
override
Operators
-
operator ==(
Object other) → bool -
