import 'dart:async';

import 'dart:io';
import 'package:device_info_csx/device_info_csx.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  runZonedGuarded(() {
    runApp(MyApp());
  }, (dynamic error, dynamic stack) {
    print(error);
    print(stack);
  });
}

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  Map<String, dynamic> _deviceData = {};

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

  Future<void> initPlatformState() async {
    Map<String, dynamic> deviceData = {};

    try {
      if (Platform.isAndroid) {
        // 获取Android设备信息
        deviceData = (await DeviceInfoCsx.androidInfo()).toJson();
      } else if (Platform.isIOS) {
        // 获取iOS设备信息
        deviceData = (await DeviceInfoCsx.iosInfo()).toJson();
      }
    } on PlatformException {
      // 处理异常情况
      deviceData = {'Error:': 'Failed to get platform version.'};
    }

    if (!mounted) return;

    setState(() {
      _deviceData = deviceData;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text(
              Platform.isAndroid ? 'Android 设备信息' : 'iOS 设备信息'),
        ),
        body: ListView(
          children: _deviceData.keys.map((String property) {
            return Row(
              children: <Widget>[
                Container(
                  padding: const EdgeInsets.all(10.0),
                  child: Text(
                    property,
                    style: const TextStyle(
                      fontWeight: FontWeight.bold,
                    ),
                  ),
                ),
                Expanded(
                    child: Container(
                  padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 10.0),
                  child: Text(
                    '${_deviceData[property]}',
                    maxLines: 1000,
                    overflow: TextOverflow.ellipsis,
                  ),
                )),
              ],
            );
          }).toList(),
        ),
      ),
    );
  }
}

代码说明

1. 导入必要的库:

   import 'dart:async';
   import 'dart:io';
   import 'package:device_info_csx/device_info_csx.dart';
   import 'package:flutter/material.dart';
   import 'package:flutter/services.dart';
   

2. 定义主应用类 MyApp:

   class MyApp extends StatefulWidget {
     [@override](/user/override)
     _MyAppState createState() => _MyAppState();
   }
   

3. 初始化设备信息:

   class _MyAppState extends State<MyApp> {
     Map<String, dynamic> _deviceData = {};
   
     [@override](/user/override)
     void initState() {
       super.initState();
       initPlatformState();
     }
   
     Future<void> initPlatformState() async {
       Map<String, dynamic> deviceData = {};
   
       try {
         if (Platform.isAndroid) {
           deviceData = (await DeviceInfoCsx.androidInfo()).toJson();
         } else if (Platform.isIOS) {
           deviceData = (await DeviceInfoCsx.iosInfo()).toJson();
         }
       } on PlatformException {
         deviceData = {'Error:': 'Failed to get platform version.'};
       }
   
       if (!mounted) return;
   
       setState(() {
         _deviceData = deviceData;
       });
     }
   

4. 构建UI:

   [@override](/user/override)
   Widget build(BuildContext context) {
     return MaterialApp(
       home: Scaffold(
         appBar: AppBar(
           title: Text(
               Platform.isAndroid ? 'Android 设备信息' : 'iOS 设备信息'),
         ),
         body: ListView(
           children: _deviceData.keys.map((String property) {
             return Row(
               children: <Widget>[
                 Container(
                   padding: const EdgeInsets.all(10.0),
                   child: Text(
                     property,
                     style: const TextStyle(
                       fontWeight: FontWeight.bold,
                     ),
                   ),
                 ),
                 Expanded(
                     child: Container(
                   padding: const EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 10.0),
                   child: Text(
                     '${_deviceData[property]}',
                     maxLines: 1000,
                     overflow: TextOverflow.ellipsis,
                   ),
                 )),
               ],
             );
           }).toList(),
         ),
       ),
     );
   }
