I have 2 pages PAGE A and PAGE B. I navigate form PAGE A -> PAGE B and do edit some data, or toggle a setting. Now I want to navigate form PAGE B -> PAGE A and also what that a parameter would be send on navigator pop method. Now my question:

How I can access to these parameter in PAGE A?

 Navigator.pop(context, this.selectedEquipmentId);

In fact you got to return something when you ends PageA. I put you an exemple with a popup to select an adress i made recently, this work exactly the same if this is not a popup.

Future<PlacesDetailsResponse> showAdressPicker(@required BuildContext context) async 
 assert(context != null);
 return await showDialog<PlacesDetailsResponse>(
 context: context,
 builder: (BuildContext context) => AdressPickerComponent(),
 );

You can send a result from Navigator.pop(...) and get it from PageA

Navigator.pop(context, result)

Just put anything you want in result, (here i created a class named PlacesDetailsResponse, use yours or just Int, String...).
Now In pageA when you call this

showAdressPicker(context: context).then((PlacesDetailsResponse value) 
 //do whatever you want here
 // this fires when PageB call previous to PageA
);
