Description:

adblock detector

Cross Platform AdBlock Detector for Flutter. Detects if the user has an AdBlocker enabled.

Features #

Check if a user has a DNS level AdBlocker enabled (PiHole, AdGuard DNS, uBlock, brave shields)
Check if a user has AdGuard DNS enabled

Warning #
Please use this package responsibly!
Usage #
AdBlockDetector adBlockDetector = AdBlockDetector();

bool isAdblocking = await adBlockDetector
.isAdBlockEnabled(testAdNetworks: [AdNetworks.googleAdMob]);
copied to clipboard

Built In Ad Networks: AdNetworks.googleAdMob, AdNetworks.mediaNet, AdNetworks.appSumari, AdNetworks.startApp, AdNetworks.adColony
Keep in mind some AdNetworks are blocked in some countries (like China). Google AdMob is not blocked in China

Passing in Custom Ad Networks #
AdBlockDetector adBlockDetector = AdBlockDetector();

bool isAdblocking = await adBlockDetector
.isAdBlockEnabled(testAdNetworks: [], customAdNetworks[Uri.parse('https://a-test-url-for-the-adnetwork.com')]);
copied to clipboard
Checking Network Connectivity #

By default, this package will attempt to send a get request to https://example.com to check if we have internet connection
If no internet connection is detected, isAdBlockEnabled() will return false (this is to prevent false positives)

You can change the test URL as shown below. Keep in mind not all URLs are available everywhere (google.com is blocked in China)
AdBlockDetector adBlockDetector = AdBlockDetector();

adBlockDetector.testHost = Uri.parse('https://cdn.vibin.llc/test.txt');
// this URL is self hosted and saved bandwidth rather than loading example.com's HTML

bool isAdblocking = await adBlockDetector
.isAdBlockEnabled(testAdNetworks: [AdNetworks.googleAdMob]);
copied to clipboard

Make sure it is a valid URL, and that the URL returns a 200 status code (not 404 page not found, otherwise that will be considered as the device being offline)

Checking if a user is using AdGuard DNS #

AdGuard DNS is a popular way to do DNS-level adblocking. If you would like to show instructions on how to disable it, or collect analytics for whatever reason you can do so like this:

AdBlockDetector adBlockDetector = AdBlockDetector();
bool isAdGuardDns = await adBlockDetector.isAdguardDNS();
