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}‘),
          ],
        )
    );
  }
}
