Flutter设备市场名称获取插件device_market_name的使用

Flutter设备市场名称获取插件device_market_name的使用

device_market_name 是一个小型插件，用于根据设备型号代码（例如 SM-G970F 对应 Galaxy s10e，iPhone13,2 对应 iPhone 12）获取设备市场名称。该插件适用于带有 GMS 的 Android 设备和 iOS 设备。

你可以通过运行以下命令来更新数据库：

python3 db_update.py

以下是使用 device_market_name 插件的完整示例代码：

import 'dart:io';

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'DeviceMarketName',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'DeviceMarketName'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key? key, required this.title}) : super(key: key);
  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String? marketName;
  String? modelCode;

  @override
  void initState() {
    asyncInit();
    super.initState();
  }

  asyncInit() async {
    /// E.g. 获取其他平台和设备的市场名称
    print(await DeviceMarketName().getMarketName('iPhone14,2', platform: TargetPlatform.iOS));
    print(await DeviceMarketName().getMarketName('SM-F900U1', platform: TargetPlatform.android));

    ///
    /// E.g. 获取当前设备的市场名称
    /// 要获取设备型号代码，请使用例如：
    /// [device_info_plus] - https://pub.dev/packages/device_info_plus
    ///
    try {
      if (Platform.isAndroid) {
        final deviceInfo = await DeviceInfoPlugin().androidInfo;
        modelCode = deviceInfo.model;
      } else if (Platform.isIOS) {
        final deviceInfo = await DeviceInfoPlugin().iosInfo;
        modelCode = deviceInfo.utsname.machine;
      }
    } catch (_) {
      modelCode = 'unknown';
    }
    if (mounted) setState(() {});

    try {
      marketName = await DeviceMarketName().getMarketName(modelCode!);
      ///
      /// [withoutNetwork] 只在 iOS 设备上有效
      /// marketName = await DeviceMarketName()
      ///     .getMarketName(modelCode!, withoutNetwork: true);
      ///
    } catch (_) {
      marketName = 'unknown';
    }
    if (mounted) setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              'ModelCode: $modelCode',
            ),
            Text(
              'MarketName: $marketName',
            ),
          ],
        ),
      ),
    );
  }
}

代码解释

1. 导入必要的库：

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

2. 主应用入口：

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

3. 定义 MyApp 类：

   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         title: 'DeviceMarketName',
         theme: ThemeData(
           primarySwatch: Colors.blue,
         ),
         home: MyHomePage(title: 'DeviceMarketName'),
       );
     }
   }
   

4. 定义 MyHomePage 类：

   class MyHomePage extends StatefulWidget {
     MyHomePage({Key? key, required this.title}) : super(key: key);
     final String title;
   
     @override
     _MyHomePageState createState() => _MyHomePageState();
   }
   

5. 定义 _MyHomePageState 类：

   class _MyHomePageState extends State<MyHomePage> {
     String? marketName;
     String? modelCode;
   
     @override
     void initState() {
       asyncInit();
       super.initState();
     }
   
     asyncInit() async {
       // 获取其他平台和设备的市场名称
       print(await DeviceMarketName().getMarketName('iPhone14,2', platform: TargetPlatform.iOS));
       print(await DeviceMarketName().getMarketName('SM-F900U1', platform: TargetPlatform.android));
   
       // 获取当前设备的市场名称
       try {
         if (Platform.isAndroid) {
           final deviceInfo = await DeviceInfoPlugin().androidInfo;
           modelCode = deviceInfo.model;
         } else if (Platform.isIOS) {
           final deviceInfo = await DeviceInfoPlugin().iosInfo;
           modelCode = deviceInfo.utsname.machine;
         }
       } catch (_) {
         modelCode = 'unknown';
       }
       if (mounted) setState(() {});
   
       try {
         marketName = await DeviceMarketName().getMarketName(modelCode!);
       } catch (_) {
         marketName = 'unknown';
       }
       if (mounted) setState(() {});
     }
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text(widget.title),
         ),
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: [
               Text(
                 'ModelCode: $modelCode',
               ),
               Text(
                 'MarketName: $marketName',
               ),
             ],
           ),
         ),
       );
     }
   }
