unable to open my custom widget picker

[jpainam]

Hi, i'm not able to open my custom widget using the api your provider PickerWidget. The example you gave uses a modalBottomSheet. What if i want to use a widget that takes the whole screen? Using this code. nothing is opened:

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:maraka/screens/publish/picker/picker_widget.dart';
import 'package:media_picker_builder/data/media_file.dart';
import 'package:media_picker_builder/media_picker_builder.dart';
import 'package:permission_handler/permission_handler.dart';

class PickImageScreen extends StatefulWidget {
  @override
  _PickImageScreenState createState() => _PickImageScreenState();
}

class _PickImageScreenState extends State<PickImageScreen> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text('Picker Demo'),
        ),
        body: Center(
          child: RaisedButton(
            child: const Text("Albums"),
            onPressed: () {
              _checkPermission().then((granted) {
                if (!granted) return;

                // To build your own custom picker use this api

                PickerWidget(
                  withImages: true,
                  withVideos: true,
                  onDone: (Set<MediaFile> selectedFiles) {
                    print(selectedFiles);
                    Navigator.pop(context);
                  },
                  onCancel: () {
                    print("Cancelled");
                    //Navigator.pop(context);
                  },
                );

                // If you are happy with the example picker then you use this!
                //_buildPicker();
              });
            },
          ),
        ),
    );
  }

  Future<bool> _checkPermission() async {
    final permissionStorageGroup =
    Platform.isIOS ? PermissionGroup.photos : PermissionGroup.storage;
    Map<PermissionGroup, PermissionStatus> res =
    await PermissionHandler().requestPermissions([
      permissionStorageGroup,
    ]);
    return res[permissionStorageGroup] == PermissionStatus.granted;
  }
}
