Question

请帮助我使用凝结器颤振软件包时遇到麻烦，我不知道出了什么问题，但是没有打印位置。我的功能被调用，但是纬度和经度没有被打印我已经在物理设备上授予了位置许可，我还在清单文件中添加了Internet许可

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

class LoadingScreen extends StatefulWidget {
  @override
  _LoadingScreenState createState() => _LoadingScreenState();
}

class _LoadingScreenState extends State<LoadingScreen> {
  void getLocation() async {
    print("inside get locaion");
    Position position = await Geolocator()
        .getCurrentPosition(desiredAccuracy: LocationAccuracy.low);
    print(position);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RaisedButton(
          onPressed: () {
            print("calling get location");
            getLocation();
          },
          child: Text('Get Location'),
        ),
      ),
    );
  }
}

这是我的androidManifest.xml文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="co.appbrewery.clima">
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />

    <!-- io.flutter.app.FlutterApplication is an android.app.Application that
         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->

            <!-- This keeps the window background of the activity showing

            <meta-data
