init method

@override Cmd? init()

Returns an optional command to execute on program startup.

This is called once when the program starts, after the initial view has been rendered. Use it to:

• Start timers for animations
• Fetch initial data
• Set up subscriptions

Return null if no initialization is needed.

Implementation

@override
Cmd? init() {
  final cmds = <Cmd>[Cmd.requestBackgroundColorReport()];

  if (enableRenderMetricsInjection) {
    cmds.add(
      Cmd.listen<RenderMetricsInjection>(
        RenderMetricsInjector.instance.stream,
        onData: (injection) => _RenderMetricsInjectionMsg(injection),
      ),
    );
  }

  final initCmd = _tree.collectHandleInit();
  if (initCmd != null) cmds.add(initCmd);
  return ParallelCmd(cmds);
}
