Flutter设备管理功能插件device_plugin的使用

介绍

device_plugin 是一个用于获取设备信息的 Flutter 插件。它支持获取 Android 设备信息和应用列表，并且已经适配到 Android 10 及以上版本。此外，该插件也适配了 iOS 平台，支持到 iPhone13。

使用示例

以下是如何在 Flutter 应用中使用 device_plugin 的示例代码：

import 'dart:async';
import 'dart:io';

import 'package:device_plugin/device_plugin.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

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

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

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  String? power;
  String? barnds;
  String? model;
  String? cpuModel;
  String? cpuCores;
  bool? isEmulator;
  Memory? memory;
  Space? space;

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
    _getDevice();
  }

  // 初始化平台状态
  Future<void> initPlatformState() async {
    String platformVersion;
    try {
      platformVersion = await DevicePlugin.platformVersion ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }
    if (!mounted) return;
    setState(() {
      _platformVersion = platformVersion;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('设备信息插件示例'),
        ),
        body: SingleChildScrollView(
          physics: const AlwaysScrollableScrollPhysics(),
          child: Column(
            children: [
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(_platformVersion),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(power ?? ""),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(barnds ?? ""),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(model ?? ""),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(cpuModel ?? ""),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(cpuCores ?? ""),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(isEmulator == true ? "是模拟器" : "不是模拟器"),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(
                  "${memory?.freeMemory.toString() ?? ""}/${memory?.totalMemory.toString() ?? ""}",
                ),
              ),
              Container(
                alignment: Alignment.center,
                margin: const EdgeInsets.only(top: 10),
                child: Text(

                ),
              ),
            ],
          ),
        ),
      ),
    );
  }

  // 获取设备信息
  _getDevice() async {
    DevicePlugin.init();
