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: [

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: [

Text(‘${gps.longitude}‘),

Text(‘${gps.latitude}‘),

Text(‘${gps.accuracy}‘),

],

)

);

}

}
