wifi_hunter's Introduction

wifi_hunter

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.

wifi_hunter's Issues

iOs support

This is exactly what we need 👍
Any chances you port it for iOs?

hello, the scan button turns red and then turns blue and the list doesn't generates,

Need info

Hi,
I am Federico and I'm using this Flutter libraty to get the list of APs from my phone, but I can't see any info. I implemented my code in a very similar way as the example code, but with no success.
Can you give me more details on how to get AP list in the proper way?
Thank you.

The app will flash back when scanning Wi-Fi is not working

I just clone this repo and build.
It just give me the error below

Query: Is there any option to listen to a particular SSID?

Hello @klydra ,

I found ur package very useful, but I want to know whether there is any options/feature that I can listen to a particular SSID to get the live updates ?

iOS support

Is there any change iOS support will get built in?

WiFi Scan failed error

I am using package example and i'm taking this issue ;

PlatformException(2, WiFi Scan failed. Most likely your app is being throttled. Check out https://developer.android.com/guide/topics/connectivity/wifi-scan#wifi-scan-throttling for more information., null, null)

How can i solve this?

Get Started code has errors.

Below is the resolved code.

import 'package:flutter/material.dart';

class _MyAppState extends State<MyApp> {

  }
}

[enhancement] Wifi's channel

It's possible to get the Wifi channel?

Thanks;

deprecated API

I get this error while building:

.pub-cache/hosted/pub.dartlang.org/wifi_hunter-1.1.0/android/src/main/java/klydra/wifi_hunter/WiFiHunterPlugin.java uses or overrides a deprecated API.

Negative timestamp value

After running the example app that you have provided, sometimes the app shows negative timestamp values. The timestamp value which is the microseconds passed after the device reboot shouldn't be negative and I suspect its happening because of int overflow. (timestamp is being cast to Int, shouldn't it be long?)

wifi_hunter/android/src/main/java/klydra/wifi_hunter/WiFiHunterPlugin.java

Line 87 in 577a5c1

timestamps.add((int) scanResult.timestamp);
