Thank you so much I am able now to control my Xamarin app with wpf
That sounds amazing!
Hi, thank you for sharing all this tips with the cummunity. Can you please do a video on firebase authentication?
This is pretty exciting because this is gonna enable things like live chatting, live location sharing, etc. 👍🏼
Exactly! You can do amazing things with this!
This is kinda exciting... Couple location based apps I want to make along with some data included. Your other videos are great too. Thanks for sharing.
Good luck!
wow!! another firebase video, thank you. Did you gonna do Firebase In-App Messaging implementation in Xamarin? Because it's hard to find this topic :(
Just what i needed. James en Gerald, dank je.
Great! Thanks Anand!
Thanks,
I noticed that the real time updating is working for a while when I open the app, then it freazes and does not update data automatically, so I wrap the stack layout within RefreshView.
I dont want to tweak the code I want the data to be updated automatically.
Thank you a lot. Now, i am building an app with net maui with firebase realtime db, it works well, but i can't disconnect the app from firebase, Dispose() method works, i am not getting new messages from firebase, but in the firebase console, usage tab, i see that my app is not disconnected
Thanks for posting this video. I attempted to execute your code with my own Firebase DB but when posting a text message via the Entry on the XFFirebaseRealtimeDBSample project, post appears to be successful but when I view my Firebase DB there is no data. I received no errors. What I did was break the projects up into separate ones and get the same results. The client code throws an error. I must be doing something wrong but not sure what it is. I used your code verbatim but error city.
Awesome, thanks Gerald. Would you please make a video like this for integrating Firebase Firestore with .NET MAUI targeting .NET 7 by chance?
Thanks a lot Gerard. Super helpful as always. I think is harder to get working firestore. Maybe is not. It would be awesome if you could cover it
I’ll look into it!
that's amazing 👌
Thanks a lot 😊
We need more firebase and xamarin.forms videos along with some firebase server-side restrictions and coding.
Will see what I can do about that
See th-cam.com/video/AVoPYLwSfHc/w-d-xo.html
@@MihaiMoisei thanks for sharing Mihai!
When do you plan on doing one of these with .Net Maui? I'm looking for a training video where you logon to something like Firebase or AirTable and get a person's ID (assuming ID & Password are valid), then proceed to find rows with that ID in some other Firebase or AirTable tables. Go, Gerald!!
I love your videos, so helpful to me a newbie Xamarin Forms / Firebase developer. Is there a simple way to get the data once on page load if I want to display static data (from a Firebase collection) in a CollectionView, including an image URL? I don't think I need it to be observable.
It needs to be observable if you want to update the data easily and efficiently at runtime. For getting the data just use what I show in the video without the subscribe, that will just get you the list :)
Hi Gerald, would you be interested in making an updated version of this in Maui?
Hello Gerald do you have a tutorial on deleting data in the realtime db?
Hi Gerald,
How can I send data to the database offline and retrieve data from the database offline?
Thanks 👍👍👍👍
How can use filter to AsObservable method,
Or I want to update my View (which retrieve data from methodById(Id)) instantly..
Do you have an example but using email and password credentials? Because every example I see on the internet are using no rules and that makes it insecure.
Great introduction and to-the-point information! I am totally new to MAUI and wondering if the same could be applied to MAUI as well.
If the plug-in can be installer on .NET MAUI it would work exactly the same :)
@@jfversluis not working on .net maui
Could you please make a video on firebase crashlytics? It would be really helpful. Thanks in advance
Great Video, Can you make a video on how to retrieve specific record from Firebase? Firebase is good to store objects, is it possible to create a query to select one object with specific text or id?
Wow, for me it was a first introduction to Firebase Database, thanks 🙏
But now I'm wondering, could it fully replace the backend api with storing data in azure sql or cosmos 🤔
Or maybe the following scheme: mobile -> rest api -> firebase -> mobile. Sorry, just thinking out loud 😄
Sure! It all depends on what to use and how you want to use it. People are definitely using this in production instead of relational databases. Also, CosmosDB can have DocumentDBs as well :)
NIce, that's the kind of video that I was looking for (Discord question :p). The nice thing is coding, is when you reply to one question, you open 3 others xD Thanks Gerlald !
Ooh perfect! Glad you found it 😄
Thank you Gerald, gread video as always 😄. Do you plan on making a video on how to post an image to firebase?
You mean Firebase storage?
@@jfversluis yes
Do some authentication videos with firebase please
Hola Gerald, excelente aporte, se podrá hacer lo mismo con Maui?
Hola! Gracias! You should be able to do that. Not sure if this plugin was made compatible with .NET MAUI yet...
@@jfversluis funciona para Maui, dejo este comentario por si es útil para alguien. Saludos.
I have a question
Do you have to configure each platform you develop with Google-service.json file ?
The thing is when I used firebase, the response takes a long time to upload data
Thanks
Best regards
Depends on what you want to do I think. You can definitely use the same json file, but in Xamarin.Forms those are separate projects so either put the file in each project or better maybe to use a symbolic link
Hi Gerald. Nice video. THX!
I'm looking for months for a simple version to hold an sqlite database (for offline use) in Xamarin.Form or MAUI for Android and Windows and synchronize it with a cloud.
With your variant, I could get en put data from this Firebase Database and synchronize my local sqlite database, but it would be quite a lot of work to build this in firebase and as sqlite to get them both actual.
Maybe you have an easier solution for that.
The easiest way would be for me, to synchronise sqlite to a MSSQL-Database, but the prices are to high for me for that.
Thank you in advance and keep coding 😉

Hi Gerald, Thanks for the great videos.
I have a question.
If a record is added to a CollectionView via Firebase.
Then that item always comes at the bottom.
Is there a way to get a new record in the top line?
I've tried a lot but I can't figure this one out.
Thanks René! You can use the Insert method on your ItemsSource collection and set the Insert to 0 to add it to the top :)
@@jfversluis
Hi Gerald
Thank you so much.
DatabaseItems.Add(dbevent.Object);
Become.
DatabaseItems.Insert(0,dbevent.Object);
Zo makkelijk kan het zijn.
Als je er verstand van hebt.
Vriendelijke groet René.
@@renelok6847 Haha je moet het maar net weten ;) Succes en let me know when you need anything!
Amazing video, could you do one with firebase auth?
Thank you! I'll see if I can do that :)
Could you please post a snipped on how to sync between offline DB and online DB? That would help me so much! Thanks
A feature like that usually isn’t just a snippet of code you can’t paste in unfortunately. It’s actually a pretty hard problem and very much depends on your situation how to implement it
Hi Gerald, Is possible to use a connection string to Firebase?, currently my project use connection string
What project do you have now? I guess there are multiple ways to connect, a connection string might be one of them. Not sure :)
Hi Gerald, i have a question how can i add another property in records and read it i tried so much but icouldnot do it
The advantage of a document database is that you can just add properties and they should be available.
Do you know how it deals with a no network situation when the db has been updated while the client is offline?
I think you will have to figure out something for that :)
You can use Essentials: th-cam.com/video/aA-sA0ACum0/w-d-xo.html
Hello sir, It's me again. I was wondering, how can we use the SQL query "Select * from TableName where Field1 like "+ entryname.Text +" to Firebase RTDB? Or is there anyway to do this or not?
That's not possible, at least not with this plugin
more more more 😅😅.. anyway, thank you for this... I'm expecting another firebase videos soon...
Which one do you want to see?
@@jfversluis it will be good if we could have a chance to have an OTP with firebase and Xamarin.Forms 😀😀
@@jfversluis I'm very new to this rtdb with firebase, I just wanna ask, is it possible to have a relational database with firebase just like azure??
Possibly, but not with the real-time database
I regularly watch your channel about xamarin forms . I have a very concern about displaying pdf file data right inside the application screen. Can you do about that. I did a lot of research, but it seems that the above methods all have a black border around it, making it not very beautiful. I will thank you very much if this topic is of interest... plea
Did you see the video I have on that already?
@@jfversluis i don't want it to have a frameset when used with webview and pdfjs . I have seen a form that shows it as that of a samsung note
@@vuthuan197ss then I think your best option is to use a component from Telerik or SyncFusion etc
How about using the FireSharp library? Please demo.
Oh cool! Didn't know about that one, I will put it on the list :)
example in net maui? thx new sub
Hi Gerald! Can you make a video/sample project using Cloud Firestore with xamarin.forms? and comparison between Realtime Database vs Cloud Firestore. Thanks!
Hey there, thanks for the suggestion! Unfortunately, probably not anytime soon and as .NET MAUI comes closer I think that is where my focus will be going to the foreseeable future
@@jfversluis That's fine, looking forward for more MAUI content. Thanks!
Gerald - I would be really grateful if you have, or can direct me to, a tutorial on displaying forbade push notifications on xamarin apps while the phone is shut off (like you can do with internal notifications (??))
You mean like this one? Implement Push Notifications with FCM and Xamarin.Forms
th-cam.com/play/PLfbOp004UaYX5B2pKKp5j7QPniyLMPkSO.html
@@jfversluis I’ve implemented that - unless I did something wrong, I only see the notifications when the screen is turned on…
@@jfversluis could be I’ve over looked something. I can double-check…
Hi, thanks for the video, I have a question... How can I do to have a Shared Project?, I create one but don't show on my main project.
I’m sorry but I’m not really sure what you mean
@@jfversluis In the video, you have the app client and the app server, how do you do to have this?
@@carlosvela31 That is something I added myself :)
@@jfversluis Hi Gerald, I have other question, with this process, can I do the same but now using photos?
Gerald, is there a way to use firebase app check feature with xamarin forms?
Sorry I’m not sure what you mean? :)
@@jfversluis firebase app check is a feature that allow only accessing firebase from an unique application name or url.
@@nosolocodigos actually I found a nuget package that handles app check but it is in beta version. Do you know if there is a way to access the android and ios app device check and safetynet?
@@alessandrosimonelli5878 Did you manage to implement app check in your xamarin forms app? @Geral Versluis
I don't think this code pull the data that has already been there. Am I wrong?
Im not sure what you mean
@@jfversluis I was wrong, your code does pull the data that has already existed in the database but after a delay. I was wondering why it's working similarly like an async method but it does not have a built-in method that wait until the operation is done.
Oh man I missed it! Stupid TH-cam notifications
Oh no! Sorry about that! Glad you still got to see it!
The old 3-way binding.
Recipe for disaster!
