finalinherited

no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- internalValue → T
-
no setterinherited
- isInitialized → bool
-
Check if a signal value is set (does not subscribe)
no setter
- node ↔ Node?
-
getter/setter pairinherited
- runtimeType → Type
-

- targets ↔ Node?
-
getter/setter pairinherited
- value → T

Methods
-
afterCreate(
T val) → void - Internal hook for after a signal is created
-
beforeUpdate(
T val) → void - Internal hook for after a signal is updated
-
call(
) → T -

) → void - Dispose the signal
-
get(
) → T -

-
onDispose(
void cleanup()) → EffectCleanup - Add a cleanup function to be called when the signal is disposed
-
peek(
) → T -
In the rare instance that you have an effect that should write to another signal based on the previous value, but you don't want the effect to be subscribed to that signal, you can read a signals's previous value via
signal.peek().inherited -
subscribe(
void fn(T value)) → void Function() -
Subscribe to value changes with a dispose function
inherited
-
subscribeToNode(
Node node) → void -
inherited
-
toJson(
) → dynamic -

inherited
-
