hi_device_util 是一个用于 Flutter 的硬件设备管理插件，它可以帮助开发者获取设备的各种信息，如设备型号、操作系统版本、存储空间、电池状态等。以下是如何使用 hi_device_util 插件的基本步骤：

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 hi_device_util 插件的依赖。

dependencies:
  flutter:
    sdk: flutter
  hi_device_util: ^1.0.0  # 请根据实际版本号进行替换

然后运行 flutter pub get 来安装插件。

2. 导入插件

在需要使用 hi_device_util 的 Dart 文件中导入插件：

import 'package:hi_device_util/hi_device_util.dart';

3. 使用插件功能

hi_device_util 提供了多种方法来获取设备信息。以下是一些常见的使用示例：

获取设备型号

String deviceModel = await HiDeviceUtil.deviceModel;
print('Device Model: $deviceModel');

获取操作系统版本

String osVersion = await HiDeviceUtil.osVersion;
print('OS Version: $osVersion');

获取设备ID

String deviceId = await HiDeviceUtil.deviceId;
print('Device ID: $deviceId');

获取存储空间信息

StorageInfo storageInfo = await HiDeviceUtil.getStorageInfo();
print('Total Storage: ${storageInfo.totalSpace}');
print('Free Storage: ${storageInfo.freeSpace}');

获取电池状态

BatteryInfo batteryInfo = await HiDeviceUtil.getBatteryInfo();
print('Battery Level: ${batteryInfo.batteryLevel}%');
print('Is Charging: ${batteryInfo.isCharging}');

获取网络状态

NetworkInfo networkInfo = await HiDeviceUtil.getNetworkInfo();
print('Network Type: ${networkInfo.networkType}');
print('Is Connected: ${networkInfo.isConnected}');

4. 处理权限

在某些情况下，获取设备信息可能需要特定的权限（例如访问网络状态或存储空间）。你需要在 AndroidManifest.xml 和 Info.plist 文件中添加相应的权限声明。

Android

在 AndroidManifest.xml 中添加以下权限：

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

iOS

在 Info.plist 中添加以下键值对：

<key>NSLocalNetworkUsageDescription</key>
<string>We need access to check your network status</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>We need access to your location to check network status</string>

5. 处理异常

在使用 hi_device_util 时，可能会遇到一些异常情况，例如权限被拒绝或设备不支持某些功能。你可以使用 try-catch 块来捕获这些异常并进行相应的处理。

try {
  String deviceModel = await HiDeviceUtil.deviceModel;
  print('Device Model: $deviceModel');
} catch (e) {
  print('Failed to get device model: $e');
}

6. 完整示例

以下是一个完整的示例，展示了如何使用 hi_device_util 获取设备的各种信息：

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

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: DeviceInfoScreen(),
    );
  }
}

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

class _DeviceInfoScreenState extends State<DeviceInfoScreen> {
  String deviceModel = 'Unknown';
  String osVersion = 'Unknown';
  String deviceId = 'Unknown';
  String storageInfo = 'Unknown';
  String batteryInfo = 'Unknown';
  String networkInfo = 'Unknown';

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

  Future<void> getDeviceInfo() async {
    try {
      deviceModel = await HiDeviceUtil.deviceModel;
      osVersion = await HiDeviceUtil.osVersion;
      deviceId = await HiDeviceUtil.deviceId;

      StorageInfo storage = await HiDeviceUtil.getStorageInfo();
      storageInfo = 'Total: ${storage.totalSpace}, Free: ${storage.freeSpace}';

      BatteryInfo battery = await HiDeviceUtil.getBatteryInfo();
      batteryInfo = 'Level: ${battery.batteryLevel}%, Charging: ${battery.isCharging}';

      NetworkInfo network = await HiDeviceUtil.getNetworkInfo();
      networkInfo = 'Type: ${network.networkType}, Connected: ${network.isConnected}';

      setState(() {});
    } catch (e) {
      print('Failed to get device info: $e');
    }
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Device Info'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Text('Device Model: $deviceModel'),
            Text('OS Version: $osVersion'),
            Text('Device ID: $deviceId'),
            Text('Storage Info: $storageInfo'),
            Text('Battery Info: $batteryInfo'),
            Text('Network Info: $networkInfo'),
          ],
        ),
      ),
    );
  }
}
