Flutter 中获取设备信息 以及 获取地 理位置

一、Flutter 中获取设备信息

https://pub.dev/packages/device_info

设备信息代码

import ‘package:flutter/material.dart‘;import ‘package:device_info/device_info.dart‘;

class DevicPage extends StatefulWidget{  DevicPage({Key key});  _DevicPage createState() => _DevicPage();}

class _DevicPage extends State {  var _text;  @override  initState() {    super.initState();    _getDevice();  }  _getDevice() async{    DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();    AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;    print(‘设备信息 ${androidInfo}‘);    _text = androidInfo;  }  Widget build(BuildContext context) {    // TODO: implement build    return Scaffold(        appBar: AppBar(title: Text(‘device‘),),        body: ListView(          children: <Widget>[            Text(‘${_text.version}‘),            Text(‘${_text.board}‘),            Text(‘${_text.bootloader}‘),            Text(‘${_text.brand}‘),            Text(‘${_text.device}‘),            Text(‘${_text.display}‘),            Text(‘${_text.fingerprint}‘),            Text(‘${_text.hardware}‘),            Text(‘${_text.host}‘),            Text(‘${_text.id}‘),            Text(‘${_text.manufacturer}‘),            Text(‘${_text.model}‘),            Text(‘${_text.product}‘),            Text(‘${_text.tags}‘),            Text(‘${_text.type}‘),            Text(‘${_text.isPhysicalDevice}‘),            Text(‘${_text.androidId}‘),          ],        )    );  }}

二、Flutter 中获取设备信息

https://pub.dev/packages/device_info

三、Flutter 中使用高德定位准备工作获取 key

1、申请成为开发者

2、创建应用配置获取 Key （参考教程演示）

https://lbs.amap.com/api/android-sdk/guide/create-project/get-key

四、Flutter 实现用高德定位

https://pub.dev/packages/amap_location

注意点

manifestPlaceholders = [AMAP_KEY : "ad2d13e8fab8a607b4707a598e32fc70"]  // 自己的高德key

注意 添加 dependencies 到 andriod 里面 和 manifestPlaceholders = [AMAP_KEY : "ad2d13e8fab8a607b4707a598e32fc70"] 配置同级,不是外层的 dependencies

dependencies {    /// 注意这里需要在主项目增加一条依赖，否则可能发生编译不通过的情况    implementation ‘com.amap.api:location:latest.integration‘}

定位案例代码

import ‘package:flutter/material.dart‘;import ‘package:amap_location/amap_location.dart‘;

class GpsPage extends StatefulWidget{  GpsPage({Key key});  _GpsPage createState() => _GpsPage();}

class _GpsPage extends State {  var gps;  @override  initState() {    super.initState();    _getGps();  }  _getGps() async{    var reult = await AMapLocationClient.startup(new AMapLocationOption( desiredAccuracy:CLLocationAccuracy.kCLLocationAccuracyHundredMeters ));    var res = await AMapLocationClient.getLocation(true);//    print(res.accuracy);  setState(() {    gps = res;  });  }  Widget build(BuildContext context) {    // TODO: implement build    return Scaffold(        appBar: AppBar(title: Text(‘device‘),),        body: ListView(          children: <Widget>[            Text(‘${gps.longitude}‘),            Text(‘${gps.latitude}‘),            Text(‘${gps.accuracy}‘),          ],        )    );  }}
