Get.back(closeOverlays) needs better documentation

[xEyad]

Description Get.back(closeOverlays) states that it will close all open overlays until it hits a screen. in the demonstrated scenario, it will literally close all overlays including the intermediate screens. and i expected it will only close overlays until it hits the first screen.

My suggested solution my suggestion is that it should behave as i expected. or Update the documentation to reflect the current behavior. currently i solved my issue by using double Get.back() instead of Get.back(closeOverlays). but it wasted some of my time to debug it, thinking it was a problem. hopefully this saves someone else time.

Reproduction code

  runApp(sandbox());

dynamic sandbox()
{
  return GetMaterialApp(
        title: 'Getx issue',
        debugShowCheckedModeBanner: false,
        home: EntryPage()); 
}


class EntryPage extends StatelessWidget 
{
   @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Entry page'),),
      body: Center(
        child: RaisedButton(child: Text("open BottomSheet "),onPressed: ()=>Get.bottomSheet(BottomSheet1()),
    ),
      ));
  }
}

class Screen1 extends StatelessWidget 
{
  Screen1();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(child: 
      Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
        RaisedButton(child: Text("go to entry page"),onPressed: ()=>Get.off(EntryPage()))
      ],)
    ,),
    );
  }
}

class Screen2 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(child: RaisedButton(child: Text('open dialog '),onPressed: ()=>Get.dialog(Dialog1()),)),
    );
  }
}


class Dialog1 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Center(child: RaisedButton(child: Text('Get.back(closeOverlays:true)'),onPressed: ()=>Get.back(closeOverlays:true),color: Colors.cyanAccent,));
  }
}

class BottomSheet1 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return RaisedButton(child: Text('Go to Screen 2'),onPressed: ()=>Get.to(Screen2()),);
  }
}

To Reproduce Steps to reproduce the behavior:

1. follow the buttons in the demo
2. notice the behavior when clicking Get.back(closeOverlays:true) button

Expected behavior it will only close overlays until it hits the first full screen.
