[移动开发]flutter获取设备信息(device_info_plus)

flutter获取设备信息

这里我们使用的是第三方库中的device_info_plus来实现，device_info已经被device_info_plus取代
地址：https://pub.dev/packages/device_info_plus

1. 在pubspec.yaml中添加依赖

dependencies:
  device_info: ^2.0.3

使用时导包

import 'package:device_info/device_info.dart';

2. 使用

在这里插入图片描述

// ignore_for_file: avoid_print

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

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  _getDevice() async {
    DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
    AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
    print('版本号为 ${androidInfo.androidId}'); // e.g. "Moto G (4)"
  }

  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text("WebView"),
        ),
        body: Column(
          children: [
            ElevatedButton(
                onPressed: () {
                  _getDevice();
                },
                child: Text("获取设备信息")),
          ],
        ));
  }
}
