close panel when i press on back

_pc.hide() should be replaced with _pc.close().

Here is a sample main.dart:

import 'package:flutter/material.dart';
import 'package:sliding_up_panel/sliding_up_panel.dart';

void main() => runApp(Playground());

class Playground extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Playground',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}


class _HomePageState extends State<HomePage> {
  PanelController _pc = new PanelController();

  Widget build(BuildContext context){
    return WillPopScope(
      onWillPop: _onWillPop,
      child: Material(
        child: SlidingUpPanel(
          panel: Center(child: Text("Panel")),
          body: Center(child: Text("Body"),),
          collapsed: Container(color: Colors.orange,),
          parallaxEnabled: true,
          controller: _pc,
        )
      ),
    );
  }

  Future<bool> _onWillPop() async{
    if(_pc.isPanelOpen()){
      _pc.close();
      return false;
    }else{
      return true;
    }
  }

}

          collapsed: Container(color: Colors.orange,),
          parallaxEnabled: true,
          controller: _pc,
        )
      ),
    );
  }

  Future<bool> _onWillPop() async{
    if(_pc.isPanelOpen()){
      _pc.close();
      return false;
    }else{
      return true;
    }
  }

}

This only works for collapsing the panel when pressing the back button.

But WillPopScope is preventing closing the application when the panel is not open.

Any solution for this?
