value property

@override T get value

Returns the current value and establishes a reactive dependency.

When accessed within a reactive context (like a Computed or Effect), the context will be notified when this signal changes.

Example:

final counter = Signal(0);
final doubled = Computed(() => counter.value * 2); // Creates dependency

Implementation

@override
T get value {
  // Trigger lazy initialization
  if (!_isInitialized) {
    _loadSync();
  }
  return super.value;
}

@override set value (T newValue)

Sets a new value for the signal and notifies subscribers when it changes.

Parameters:

• value: The new value to set

Example:

final counter = Signal(0);
counter.value = 10;
counter.set(11);

Sets a new value for the signal and notifies subscribers when it changes.

Parameters:

• value: The new value to set

Example:

final counter = Signal(0);
counter.value = 10;
counter.set(11);

Implementation

@override
set value(T newValue) {
  if (!_isInitialized) {
    _loadSync();
  }

  super.value = newValue;
  _version++;

  _scheduleWrite(newValue);
}
