A flutter package to hunt down info from all WiFi APs around you.

Demonstration

Getting Started

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

import 'package:wifi_hunter/wifi_hunter.dart';
import 'package:wifi_hunter/wifi_hunter_result.dart';

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

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  WiFiHunterResult wiFiHunterResult = WiFiHunterResult();
  
  Future<void> huntWiFis() async {
    try {
      wiFiHunterResult = (await WiFiHunter.huntWiFiNetworks)!;
    } on PlatformException catch (exception) {
      print(exception.toString());
    }
    
    for (var i = 0; i < wiFiHunterResult.results.length) {
      print(wiFiHunterResult.results[i].ssid);
      print(wiFiHunterResult.results[i].bssid);
      print(wiFiHunterResult.results[i].capabilities);
      print(wiFiHunterResult.results[i].frequency);
      print(wiFiHunterResult.results[i].level);
      print(wiFiHunterResult.results[i].channelWidth);
      print(wiFiHunterResult.results[i].timestamp);
    }

    if (!mounted) return;
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
      appBar: AppBar(
        title: const Text('WiFiHunter example app'),
      ),
      body: ElevatedButton(
        onPressed: () => huntWiFis(),
        child: const Text('Hunt Networks')
      )
    );
  }
}

Functionality and Features

Here is what infos you can get by using this package :

• String[] SSIDs

• String[] BSSIDs

• String[] Signal strength

• int[] Frequencies

• int[] Capabilities

• int[] Channel widths

• long[] Timestamps (of information retrieval)

  ... of all WiFi APs in reach.

Running the sample

When running the sample app, make sure you've granted it the location permissions available in the system preferences, as there is currently no permission dialog implemented in the example app.
The permission settings are available under Settings > Apps > wifi_hunter_example > Permissions > Location > Allow only while using the app

Android WiFi Scan Throttling

Starting with Android 8.0 and up, the operating system severely limits the number of WiFi scans.
Please keep this limit in mind when implementing your scan issuing logic.
Find out more about these limits on developer.android.com.

Debugging

You can get a good overview of pretty much all related log entries by searching for wifi in the Logcat output.
