2. 初始化插件并检查WiFi状态
在Flutter应用中初始化插件,并检查设备的WiFi是否已启用。
示例代码:
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:flutter_cy_wifi/flutter_cy_wifi.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatefulWidget {
const MyApp({super.key});
[@override](/user/override)
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _platformVersion = 'Unknown';
bool _isWiFiEnable = false;
final _flutterCyWifiPlugin = FlutterCyWifi();
[@override](/user/override)
void initState() {
super.initState();
initPlatformState(); // 获取平台版本
checkWiFiEnable(); // 检查WiFi是否启用
getWiFiConnectedInfo(); // 获取当前连接的WiFi信息
startScan(); // 开始WiFi扫描
connectWiFi(); // 尝试连接WiFi
disconnectWiFi(); // 断开WiFi连接
}
// 获取平台版本
Future<void> initPlatformState() async {
String platformVersion;
try {
platformVersion = await _flutterCyWifiPlugin.getPlatformVersion() ?? 'Unknown platform version';
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
if (!mounted) return;
setState(() {
_platformVersion = platformVersion;
});
}
// 检查WiFi是否启用
Future<void> checkWiFiEnable() async {
bool isEnable;
try {
isEnable = await _flutterCyWifiPlugin.checkWiFiEnable();
} on PlatformException {
isEnable = false;
}
if (!mounted) return;
setState(() {
_isWiFiEnable = isEnable;
});
}
// 获取当前连接的WiFi信息
Future<void> getWiFiConnectedInfo() async {
Map<dynamic, dynamic>? wifiConnectedInfo;
try {
wifiConnectedInfo = await _flutterCyWifiPlugin.getWiFiConnectedInfo();
} on PlatformException {
wifiConnectedInfo = {};
}
print(wifiConnectedInfo);
}
// 开始WiFi扫描
Future<void> startScan() async {
List<dynamic>? scanResults;
try {
scanResults = await _flutterCyWifiPlugin.startScan();
} on PlatformException {
scanResults = [];
}
print(scanResults);
}
// 连接WiFi
Future<void> connectWiFi() async {
bool? connectResult = false;
try {
connectResult = await _flutterCyWifiPlugin.connectWiFi({
'ssid': 'NAXCLOW',
'bssid': '00:00:00:00:00:00',
'password': '',
});
} on PlatformException {
connectResult = false;
}
print('connect WiFi result: $connectResult');
}
// 断开WiFi连接
Future<void> disconnectWiFi() async {
bool? disconnectResult = false;
try {
disconnectResult = await _flutterCyWifiPlugin.disconnectWiFi({
'ssid': 'NAXCLOW',
});
} on PlatformException {
disconnectResult = false;
}
print('disconnect WiFi result: $disconnectResult');
}
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('WiFi Plugin Example'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text('Platform Version: $_platformVersion\n'),
Text('WiFi Enabled: $_isWiFiEnable\n'),
],
),
),
);
}
}

flutter_cy_wifi
是一个用于管理 Wi-Fi 连接的 Flutter 插件。它可以帮助你在 Flutter 应用中扫描、连接、断开 Wi-Fi 网络,以及获取当前连接的 Wi-Fi 信息。以下是如何使用 flutter_cy_wifi
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 flutter_cy_wifi
插件的依赖:
dependencies:
flutter:
sdk: flutter
flutter_cy_wifi: ^0.0.1 # 请使用最新的版本号
然后运行 flutter pub get
来获取依赖。
2. 导入插件
在你的 Dart 文件中导入 flutter_cy_wifi
插件:
import 'package:flutter_cy_wifi/flutter_cy_wifi.dart';
3. 使用插件
3.1 获取 Wi-Fi 状态
你可以使用 FlutterCyWifi.getWifiState()
来获取当前 Wi-Fi 的状态:
void checkWifiState() async {
String wifiState = await FlutterCyWifi.getWifiState();
print('Wi-Fi State: $wifiState');
}
3.2 扫描 Wi-Fi 网络
使用 FlutterCyWifi.scanWifi()
来扫描附近的 Wi-Fi 网络:
void scanWifi() async {
List<WifiInfo> wifiList = await FlutterCyWifi.scanWifi();
wifiList.forEach((wifi) {
print('SSID: ${wifi.ssid}, BSSID: ${wifi.bssid}, Signal Strength: ${wifi.level}');
});
}
3.3 连接到 Wi-Fi 网络
使用 FlutterCyWifi.connectToWifi(ssid, password)
来连接到一个 Wi-Fi 网络:
void connectToWifi() async {
String ssid = 'YourNetworkSSID';
String password = 'YourNetworkPassword';
bool result = await FlutterCyWifi.connectToWifi(ssid, password);
if (result) {
print('Connected to $ssid');
} else {
print('Failed to connect to $ssid');
}
}
3.4 断开 Wi-Fi 连接
使用 FlutterCyWifi.disconnectWifi()
来断开当前的 Wi-Fi 连接:
void disconnectWifi() async {
bool result = await FlutterCyWifi.disconnectWifi();
if (result) {
print('Disconnected from Wi-Fi');
} else {
print('Failed to disconnect from Wi-Fi');
}
}
3.5 获取当前连接的 Wi-Fi 信息
使用 FlutterCyWifi.getCurrentWifiInfo()
来获取当前连接的 Wi-Fi 信息:
void getCurrentWifiInfo() async {
WifiInfo wifiInfo = await FlutterCyWifi.getCurrentWifiInfo();
print('Connected to SSID: ${wifiInfo.ssid}, BSSID: ${wifiInfo.bssid}, Signal Strength: ${wifiInfo.level}');
}
4. 处理权限
在 Android 上,使用 Wi-Fi 功能需要以下权限:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
确保在 AndroidManifest.xml
文件中添加这些权限。
5. 处理 iOS 配置
在 iOS 上,你需要在 Info.plist
文件中添加以下键值对以请求位置权限:
<key>NSLocationWhenInUseUsageDescription</key>
<string>We need your location to scan for Wi-Fi networks.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>We need your location to scan for Wi-Fi networks.</string>
6. 错误处理
在使用插件时,确保处理可能出现的异常和错误:
void connectToWifi() async {
try {
String ssid = 'YourNetworkSSID';
String password = 'YourNetworkPassword';
bool result = await FlutterCyWifi.connectToWifi(ssid, password);
if (result) {
print('Connected to $ssid');
} else {
print('Failed to connect to $ssid');
}
} catch (e) {
print('Error: $e');
}
}
7. 注意事项
- 由于涉及到 Wi-Fi 和位置权限,确保在应用中正确处理权限请求。
- 插件的功能可能因平台而异,确保在 Android 和 iOS 上测试你的应用。
8. 参考
