onInit method

@override void onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

Implementation

@override
void onInit() {
  super.onInit();

  // Receive painter engine from navigation arguments
  final args = Sint.arguments;
  if (args is List && args.isNotEmpty && args.first is NeomFrequencyPainterEngine) {
    _painterEngine = args.first;
  } else if (args is NeomFrequencyPainterEngine) {
    _painterEngine = args;
  }

  _ticker = Ticker(_onTick);
  _loadAndStart();
}
