Answer 1

I have completed with this question, i do like this:

view dialog:

class ProcessWashingDialog extends BaseWidget<ProcessWashingDialogController> {
  final int id;
  final String title;
  final VoidCallback onPressed;
  final VoidCallback onBackPressed;
  final ProcessWashingDialogController _controller;

  ProcessWashingDialog(
  this._controller,
  {
    required this.id,
    required this.title,
    required this.onPressed,
    required this.onBackPressed,
  }) : super(_controller) {
    _controller.setArguments(id);
  };

controller dialog:

void setArguments(int id) {
   _getTimeRegister(id);
}

Method 1: you can write a function that returns the value you need and then retrieves it from the controller.

Method 2: You create an id variable in the controller and then get it straight from that controller.

class Controller {
  String id;

  void getData() {
    // call api
    id = data;
  }
}

View

Text(controller.id)

Method 3: You can callback with params

Class controller {
  Function(int) onSuccess;

  void getData() {
    // call api
    onSuccess(id);
  }
}

View

void onSuccess(int id) {
  // handle id
}
