no setter, inherited

name → String?

Methods

$lifetime(Node node) → ReadLifetime<R>

Used by the registry to create a read lifetime. Bit hacky, but allows us to go from dynamic to T.

inherited

$read(AtomContext<R> ctx) → R

Used by the registry to read the atoms value.

inherited

$write(GetAtom get, SetAtom set, SetSelf<R> setSelf, W value) → void

When the atom recieves a write with the given value, this method determines the outcome.

asyncSelect<B>(B f(A value)) → AtomWithParent<Future<B>, Atom<FutureValue<A>>>

Available on Atom<FutureValue<A>>, provided by the FutureValueAtomExtension extension

Create a derived atom, that transforms an atoms value using the given function f.

filter(bool predicate(A value)) → AtomWithParent<FutureValue<A>, Atom<A>>

Available on Atom<A>, provided by the AtomExtension extension

Create a derived atom, that filters the values using the given predicate.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

rawSelect<B>(B f(FutureValue<A> value)) → AtomWithParent<B, Atom<FutureValue<A>>>

Available on Atom<FutureValue<A>>, provided by the FutureValueAtomExtension extension

Create a derived atom, that transforms an atoms value using the given function f.

select<B>(B f(A value)) → AtomWithParent<B, Atom<A>>

Available on Atom<A>, provided by the AtomExtension extension

Create a derived atom, that transforms an atoms value using the given function f.

select<B>(B f(A value)) → AtomWithParent<FutureValue<B>, Atom<FutureValue<A>>>

Available on Atom<FutureValue<A>>, provided by the FutureValueAtomExtension extension

Create a derived atom, that transforms an atoms value using the given function f.

toString() → String

A string representation of this object.

inherited

withInitialValue(R value, {bool keepAlive = true}) → AtomInitialValue<R>

Create an initial value override, which can be given to an AtomScope or AtomRegistry.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
