XMLStreamException-位置[1,0]处的流意外结束

Question

我正在Android项目中使用Simple框架从文件夹中读取xml文件。在这里，我正在浏览文件夹。我已经确认文件确实存在。

import 'package:flutter/material.dart';
import 'package:location/location.dart';
import 'package:flutter/services.dart';
import 'package:simple_permissions/simple_permissions.dart';
import 'package:baby_names/Widgets/babies.dart';
import 'package:baby_names/Widgets/location.dart';

class LocationState extends State {

  final myController = TextEditingController();
  Location _location = new Location();
  Map<String, double> _currentLocation;

  String error;

  _getLocation() async {
    Map<String, double> location;
    try {
      await SimplePermissions.requestPermission(Permission.AccessFineLocation);
      location = await _location.getLocation();
      error = null;
    } on PlatformException catch (e) {
      if (e.code == 'PERMISSION_DENIED') {
        error = 'Permission denied';
      } else if (e.code == 'PERMISSION_DENIED_NEVER_ASK') {
        error =
        'Permission denied - please ask the user to enable it from the app settings';
      }
      location = null;
    }
    print("error $error");

    setState(() {
      _currentLocation = location;
      update_controller(_currentLocation);
      print(_currentLocation);
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Baby Name Votes')),
      body: _buildBody(context),
    );
  }

  Widget _buildBody(BuildContext context) {
    return
      Column(
        children: <Widget>[
          LocationCapture(_getLocation, myController),
          Expanded(
            child: BabiesVotes(),
          ),
        ],
      );
  }

  void update_controller(Map<String, double> currentLocation) {
    myController.text = ('${_currentLocation["latitude"]}, ${_currentLocation["longitude"]}' ?? 'Grant location Access');
  }
}

我从文件中读取的部分似乎出了点问题。根据文档，我做得正确，但是，我遇到了以下异常：
