NeuronControllerShorthand extension

Extension providing ultra-short signal factory methods on NeuronController.

This extension uses $ prefix for maximum brevity. Choose this style if you prefer concise code and your team is familiar with the convention.

Usage

class CounterController extends NeuronController {
  late final count = $(0);           // Signal<int>
  late final name = $('');           // Signal<String>
  late final user = $async<User>();
  late final doubled = $computed(() => count.val * 2);
}

Comparison

Verbose Clean Short
Signal<int>(0).bind(this) signal(0) $(0)
AsyncSignal<T>().bind(this) asyncSignal<T>() $async<T>()
Computed(() => x).bind(this) computed(() => x) $computed(() => x)
on
