Flutter设备信息获取插件device_meta的使用

Device Meta

device_meta 是一个用于在Flutter中处理设备信息的插件。它允许您获取设备名称、型号、品牌、制造商、uuid、版本、平台类型和用户代理。

Getting started

Installation

要开始使用 device_meta 插件，您需要将其添加到项目的依赖项中。可以通过编辑 pubspec.yaml 文件来实现：

dependencies:
  device_meta: ^2.1.2

或者直接使用Dart命令行工具：

dart pub add device_meta

Usage

以下是如何使用 device_meta 的示例代码：

import 'package:device_meta/device_meta.dart';

void main() async {
  // 初始化DeviceMeta实例
  DeviceMeta deviceMeta = await DeviceMeta.init(storageKey: "exampleapp");

  // 打印设备信息
  print('Device Name: ${deviceMeta.name}');
  print('Model: ${deviceMeta.model}');
  print('Brand: ${deviceMeta.brand}');
  print('UUID: ${deviceMeta.uuid}');
  print('Version: ${deviceMeta.version}');
  print('Platform Type: ${deviceMeta.platformType}');
  print('User Agent: ${deviceMeta.userAgent}');
  print('To JSON: ${deviceMeta.toJson()}');

  // 添加元数据
  DeviceMeta deviceMetaWithMetaData = await DeviceMeta.init(
    storageKey: "exampleapp",
    metaData: {
      "user_id": 1,
      "app_version": "1.0.0"
    }
  );

  // 获取特定的元数据值
  print('App Version: ${deviceMetaWithMetaData.getMetaData("app_version")}');
  print('User ID: ${deviceMetaWithMetaData.getMetaData("user_id")}');

  runApp(const MyApp());
}

接下来是一个完整的Flutter应用示例，展示如何在UI中显示这些信息：

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

void main() async {
  // 初始化DeviceMeta实例
  await DeviceMeta.init(storageKey: "example");
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

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

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    DeviceMeta deviceMeta = DeviceMeta.instance;
    return Scaffold(
      appBar: AppBar(title: const Text("Device Meta")),
      body: SafeArea(
        child: Container(
          padding: const EdgeInsets.symmetric(horizontal: 8),
          width: double.infinity,
          child: ListView(
            shrinkWrap: true,
            children: [
              Text("Device meta",
                  style: Theme.of(context).textTheme.displaySmall),
              const Divider(),
              Text("Model: ${deviceMeta.model}"),
              Text("Version: ${deviceMeta.version}"),
              Text("Brand: ${deviceMeta.brand}"),
              Text("Manufacturer: ${deviceMeta.manufacturer}"),
              Text("Platform Type: ${deviceMeta.platformType}"),
              Text("UUID: ${deviceMeta.uuid}"),
              Text("UserAgent: ${deviceMeta.userAgent}"),
              Text("toJson: ${DeviceMeta.instance.toJson().toString()}"),
            ],
          ),
        ),
      ),
    );
  }
}

这个应用程序会创建一个简单的界面，在其中显示当前设备的各种信息。通过这种方式，您可以轻松地将 device_meta 集成到您的Flutter项目中，并根据需要读取和使用设备信息。
