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}‘),
],
)
);
}
}
