I want to ask if the implementation code is correct.
I want to measure Universal Analytics (UA) and Google Analytics 4 (GA4) at the same time, on the same page.
<script async src="https://www.googletagmanager.com/gtag/js?id=G-xxxxxxx"></script>
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-xxxxxxxx-x"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag() {
dataLayer.push(arguments);
}
gtag('js', new Date());
gtag('config', 'G-xxxxxxx', {'debug_mode': true});
gtag('config', 'UA-xxxxxxxx-x', {'debug_mode': true});

I have a fully functional App on Android and IOS, and now I want to have a web version taking advantage of Flutter's cross-platform features.
To do this, I created a "Chrome Device" from VS Code and I did the Firebase App registration within the Firebase console. In the index.html I included the configuration as explained in Flutter Firebase Installation Web ...

When I run the App in Chrome I get an Oh No! Error 5 in the browser and no error messages in the VS Code console.
If I include an await in the Firebase initialization line in index.html:
await firebase.initializeApp(firebaseConfig);
Again the Oh No! Error 5, but when I reload the page I get the following error on web_entrypoint.dart:
FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created -
call Firebase App.initializeApp() (app/no-app).
at Object.u [as app] (https://www.gstatic.com/firebasejs/8.6.1/firebase-app.js:1:18836) at
Object.getApp
(http://localhost:65003/packages/firebase_database_web/src/interop/app.dart.lib.js:630:89)
//... more debug lines
In my lib/src/pages/main.dart, which works fine on IOS and Android, I'm making sure to initialize the Firebase services first ...
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
final prefs = PreferenciasUsuario();
await prefs.initPrefs();
await PushNotificationsProvider.initializeApp();
FirebaseDatabase database;
database = FirebaseDatabase.instance;
database.setPersistenceEnabled(true);
database.setPersistenceCacheSizeBytes(10000000);
runApp(MyApp());
}
I've read most of the answers on the subject on StackOverflow, but they haven't worked for me, I don't know if it's because I'm doing it particularly with Flutter.
How can I resolve the No Firebase App '[DEFAULT]' error and get my application run on the web?
When we use the DFP option used to target ads with a Key/Value pair we noticed it does not work when Prebid is also running. It appears that Prebid is overriding the setTargeting option. It would seem to be a common issue, but I cannot find any information about it.
If I disable prebid, the setTargeting works fine.
I've also tried placing the setTargeting inside the pbjs.que.push function, just after pbjs.setTargetingForGPTAsync(); but that did not help.
I've paired down the code to include just the basic setup to show how we have things configured.

<script>
var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
</script>
<script>
googletag.cmd.push(function() {
googletag.defineSlot('/XXX/slot-300x250-1', [[300, 250]], 'div-gpt-ad-bigblock-1').addService(googletag.pubads());
googletag.pubads().setTargeting("pageurl", "/home/");
googletag.pubads().enableSingleRequest();
googletag.pubads().disableInitialLoad();
googletag.enableServices();
});
</script>
<!-- Prebid Boilerplate Section START -->
<script>
pbjs.que.push(function() {
pbjs.addAdUnits(adUnits);
pbjs.requestBids({
bidsBackHandler: initAdserver,
timeout: PREBID_TIMEOUT
});
});
function initAdserver() {
if (pbjs.initAdserverSet) return;
pbjs.initAdserverSet = true;
googletag.cmd.push(function() {
pbjs.que.push(function() {
pbjs.setTargetingForGPTAsync();
googletag.pubads().refresh();
});
});
}
// in case PBJS doesn't load
setTimeout(function() {
initAdserver();
}, FAILSAFE_TIMEOUT);
</script>
<!-- Prebid Boilerplate Section END -->
It's definitely the sequence of events that is wrong. I don't even think pbjs.setTargetingForGPTAsync() is needed at all, but you do need to wait for prebid to return with the bids before googletag.pubads().setTargeting("pageurl", "/home/");
You can solve this with a Promise that would be wrapped around prebid, and wait for the promise to resolve inside so something like:
var prebidPromiseResponse = new Promise( function(resolve){
pbjs.que.push(function() {
pbjs.addAdUnits(adUnits);
pbjs.requestBids({
bidsBackHandler: function(bids){
if (pbjs.initAdserverSet) return;
pbjs.initAdserverSet = true;
googletag.cmd.push(function() {
pbjs.que.push(function() {
resolve(bids);
});
});
},
timeout: PREBID_TIMEOUT
});
});
})
And then google tag
googletag.cmd.push(function() {
googletag.defineSlot('/XXX/slot-300x250-1', [[300, 250]], 'div-gpt-ad-bigblock-1').addService(googletag.pubads());
prebidPromiseResponse.then(function(bids){
googletag.pubads().setTargeting("pageurl", "/home/");
googletag.pubads().enableSingleRequest();
googletag.pubads().disableInitialLoad();
googletag.enableServices();
});
});
i use this script
<script type="text/javascript">
if(typeof(window.google_render_ad)=="undefined")
{
//document.getElementById('player-embed').innerHTML = '<center>text lablbabal)<br><img src=\"https://i.imgur.com/p7vHVHA.jpg\" /></center>';
}
</script>
but now is not working is blocking with or without adblock why??
and another script again is not working
<script type="text/javascript" src="http://domain/advert.js"></script>
<script type="text/javascript">
if (document.getElementById("tester") == undefined)
{
//document.getElementById('#disqus_thread').style.display = 'none';
document.getElementById('player-embed').innerHTML = '<center>text lalala<br><img src=\"https://i.imgur.com/p7vHVHA.jpg\" /></center>';
}
</script>
why is not working?? is the script wrong or what??
Sometimes adblock can inject false show_ads.js which could trigger a defined variable
window.google_render_ad == defined
so this is not a code issue but try BlockAdBlock they have good detection technology
I installed the plugin as mentioned in the docs
I cant find a way to get it working.

I've had issues with using the FB plugin in my app development too. Sometimes it's necessary to include the FacebookConnectPlugin.js file in your index.html, as well as include this script, which injects the Facebook Javascript SDK into your app.

Currently i am using the google cloudprint button for my site
<script src="//www.google.com/cloudprint/client/cpgadget.js"></script>
<script defer="defer">
var gadget = new cloudprint.Gadget();
gadget.setPrintButton(document.getElementById("custom_print_button"));
gadget.setPrintDocument("url", "Cloud Print test page",
"http://www.google.com/cloudprint/learn/");
</script>
I want to send an email when I hit the print button, is this possible?
No problem at all... just attach an onclick handler to the print button, or bind the click with jQuery and call a function to do your email. I used it to create a document with Ajax before it was printed:
<script>
function printIT() {
jQuery.ajax({
url: "print_this.php",
context: document.body,
success: function(responseText) {
alert("Document sent!");
return false;
}
});
}
</script>
<button id="print_button_container" class="ui-link" onclick="printIT();"></button>
<script src="//www.google.com/cloudprint/client/cpgadget.js">
</script>
<script defer="defer">
var gadget = new cloudprint.Gadget();
gadget.setPrintButton(document.getElementById("print_button_container"));
gadget.setPrintDocument("url", "My Document", "http://www.yourpath.com/yourdoc.html");
</script>
Simplified version... not tested but should work :)
