Flutter安卓工具类插件android

Flutter安卓工具类插件`android_util`的使用

获取Android IP地址

本项目是一个用于Flutter的插件包，它包含了Android和/或iOS平台上的特定实现代码。

对于Flutter开发的帮助，请查看我们的在线文档，其中包含教程、示例、移动开发指导以及完整的API参考。

使用示例

以下是使用android_util插件的完整示例代码：

代码解释

导入库

import 'dart:async';

import 'package:android_util/android_ip.dart';
import 'package:android_util/pigeon.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

初始化
```
void main() {
  runApp(MyApp());
}
```

定义状态变量

class _MyAppState extends State<MyApp> {
  String _Connecton_change = '';
  String _ondeviceconnected = '';
  String _wifiname = '';
  String _ondeviceconnected2 = '';
  String _status = '';
  String _IpAddress_Wifi_tether = 'Unknown';
  bool _isHotspot = false;
  bool _isWifi = false;
  String _IpAddress_Wifi_both = 'Unknown';
  String _IpAddress_Wifi = 'Unknown';
  String _IpAddress_Private = 'Unknown';
  String _IpAddress_USB_tether = 'Unknown';
  String _IpAddress_All = 'Unknown';
  String _IpAddress_Cellular2 = 'Unknown';
  String _IpAddress_Cellular1 = 'Unknown';
  String _IpAddress_Cell = 'Unknown';
  String _IpAddress_Blue_ther = 'Unknown';
  String _connectedlist = '';

初始化插件

late AndroidIp androidIp;

[@override](/user/override)
initState() {
  super.initState();
  androidIp = new AndroidIp();
  var listner = androidIp.onConnectivityChanged;
  var ondeviceconnected = androidIp.onDeviceConnected;
  permissionchanged();
  androidIp.onPortbyIp!.listen((event) {
    print(event);
  });

  var arguments2 = {
    'ip': '192.168.42.129',
  };
  var arguments = {
    'ip': '148.72.210.101',
    'timeout': '10000'
  };
  androidIp.onIpConnected(arguments)!.listen((event) {
    print("============>" + event);
  });

  listner!.listen((event) {
    setState(() {
      _Connecton_change = event;
    });
    initPlatformState();
  });
  ondeviceconnected!.listen((event) {
    setState(() {
      _ondeviceconnected = _ondeviceconnected + "," + event;
    });
  });

  initPlatformState();
}

处理权限更改

permissionchanged() {
  var da = androidIp.onPermissionChanged!.listen((event) {
    print("${event.name}${event.status}");
    initPlatformState();
  });
}

初始化平台状态

Future<void> initPlatformState() async {

  }

  if (!mounted) return;

  setState(() {

复制IP地址到剪贴板

_copy(String ipAddress_Wifi) {
  var clipboardData = ClipboardData(text: ipAddress_Wifi);

  Clipboard.setData(clipboardData);
}

设置设备连接监听

setLisIp() {
  setState(() {
    _ondeviceconnected2 = "";
  });

  var da = androidIp.onDeviceConnected!.listen((event) {
    setState(() {
      _ondeviceconnected2 = _ondeviceconnected2 + "," + event;
    });
  });
}

设置共享监听

setShare() {
  setState(() {
    _status = "";
  });

  var da = androidIp.onShared!.listen((event) {
    setState(() {
      _status = event;
    });
  });
}

android_util 是一个 Flutter 插件，用于在 Flutter 应用中访问 Android 平台特定的功能。它提供了一些工具类方法，帮助开发者在 Flutter 应用中调用 Android 的原生功能。

安装

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

dependencies:
  flutter:
    sdk: flutter
  android_util: ^1.0.0 # 请使用最新版本

然后运行 flutter pub get 来安装依赖。

使用

android_util 插件提供了一些常用的 Android 平台功能，例如获取设备信息、打开系统设置、检查权限等。

1. 获取设备信息

import 'package:android_util/android_util.dart';

void getDeviceInfo() async {
  String deviceModel = await AndroidUtil.deviceModel;
  String deviceManufacturer = await AndroidUtil.deviceManufacturer;
  String androidVersion = await AndroidUtil.androidVersion;

  print('Device Model: $deviceModel');
  print('Device Manufacturer: $deviceManufacturer');
  print('Android Version: $androidVersion');
}

2. 打开系统设置

import 'package:android_util/android_util.dart';

void openSettings() async {
  await AndroidUtil.openSettings();
}

3. 检查权限

import 'package:android_util/android_util.dart';

void checkPermission() async {
  bool hasPermission = await AndroidUtil.checkPermission("android.permission.CAMERA");
  if (hasPermission) {
    print("Camera permission granted");
  } else {
    print("Camera permission denied");
  }
}

4. 请求权限

import 'package:android_util/android_util.dart';

void requestPermission() async {
  bool granted = await AndroidUtil.requestPermission("android.permission.CAMERA");
  if (granted) {
    print("Camera permission granted");
  } else {
    print("Camera permission denied");
  }
}

5. 获取电池信息

import 'package:android_util/android_util.dart';

void getBatteryInfo() async {
  int batteryLevel = await AndroidUtil.batteryLevel;
  bool isCharging = await AndroidUtil.isBatteryCharging;

  print('Battery Level: $batteryLevel%');
  print('Is Charging: $isCharging');
}

注意事项

权限声明：在 Android 中，某些功能可能需要权限。你需要在 AndroidManifest.xml 文件中声明这些权限。例如，如果要访问相机权限，需要添加：
```
<uses-permission android:name="android.permission.CAMERA" />
```
权限请求：从 Android 6.0 (API 23) 开始，某些权限需要在运行时请求。你可以使用 requestPermission 方法来请求权限。
平台特定代码：android_util 插件只适用于 Android 平台。在 iOS 或其他平台上调用这些方法可能会抛出异常。你可以使用 Platform.isAndroid 来检查当前平台。
```
import 'dart:io';

if (Platform.isAndroid) {
  // 调用 Android 特定的方法
}
```
