setObservable method

Implementation

void setObservable(String? key, dynamic value)
{
  Binding? binding = Binding.fromString(key);

  if(binding == null) return;

  // Find Observable
  Observable? observable = getObservable(binding);

  // Set Value
  if (value is String && Observable.isEvalSignature(value))
  {
    value = Observable.getEvalSignature(value);
    value = Observable.doEvaluation(value);
  }

  // Create the Observable
  if (observable == null)
  {
    Scope? scope = this;
    if (binding.scope != null) scope = System.app?.scopeManager.of(binding.scope);
    if (scope != null)
    {
      var observable = StringObservable(binding.key, value, scope: this);
      scope.register(observable);
    }
  }

  // Set the Value
  else {
    observable.set(value);
