Implementation

Future<bool> trigger() async
{
  for (int i = 0; i < cases.length; i++)
  {
    if (cases[i].when != null && cases[i].call != null)
    {
      if (S.toBool(cases[i].when) == true)
      {
        await EventHandler(this).execute(cases[i].callObservable);
        if (type == 'single')
        {
          i = cases.length;
          return true;
        }
      }
