[@rajayogan8884]

Cool.. (There are actually ways to optimise this, I thought of making a video on it long back, then gave up that idea)

[@windanwin]

[@adithyashetty4255]

Hello, I get how to access multiple documents using int like 0,1,2,3 but now instead of giving auto-id to every document I choose to give a custom id like id_1, id_2, so on and now its a string so now how would I access document specifically id_1 and its fields?

[@tusharchadha4160]

hey could you help me getting that doc id

[@ASHUTOSHSINGH-oq8sc]

Finally...!! The tutorial I was looking for !! Thank you so much !

[@myfavourites4478]

[@ugandhar115]

good stuff.. thanks if the data itself not there in the collection itself does it show infinite Loading.. please wait message?

[@storylineteam]

Great Job! Please consider making a tutorial on End 2 end encryption of firetore data, i asked almost every great chanel for this as it is the most important no covered topic. It is very important for us in Europe to encrypt the collected data based on the EU law. Also for small small companies like us, using expensive apis lie Virgil is a not affordable approach. All the best from greece.

how can i get a document by giving its id . and then check if there is a document or not ...plz help

[@johnalberttalamayan6135]

Hi Raja, Im stuck with my current problem now. Im hoping you could teach me how I could retrieve document id?

[@Vathananable]

Sir what if you are reading an array of mapped objects from firebase ? How do you it

[@rajayogan8884]

I did that last week on an app I am working on.. It would be confusing if I try to explain that in text. Maybe I'll make a video later on that..

[@Vathananable]

Can I return Json Data from Fire Base into a Dart object or array ?

[@dhruvpatel9752]

Hi, Let's say I have a textformfield which is used to Add 'Category' data into the Cloud Firestore from Flutter. I am successfully able to add 'category' into the firestore database, but in the textformfield, i need a validation that says "This Category Already Exists, Please try another" by checking the data in the firestore databse. And if the user types some other category, then only the Form can be submitted. Means that there are no two documents with the same name in the collection., As i am a beginner, i would request you to make a video on that particular topic. If i am unable to make you understand what exactly I'm talking about, please let me know. Your help would be Appreciated wholeheartedly. Thank You in Advance!! :)

[@Beatmakerniko]

Exactly what i was looking, thanks!

[@muthuvinayagam7086]

Thanks Raja for this tutorial! I am using M1 - Andriod Emulator - : 5554 device, I believe there is no google play store in Emulator. hence I am facing this below issue. ** google play store is missing ** googleplayservices not available due to error 9. ** failed to update ssl contet: com.google.android.gms.common.googleplayservciesnotavailableException ------------------- I have tried to implement it in IOS. successfully established the connection, but data is not retrieved from firestore and does not display in App. 1. flutter: ====data====== Instance of 'JsonQueryDocumentSnapshot', Instance of 'JsonQueryDocumentSnapshot' 2. Also I want to understand one thing if remove "?" ==> ${snapshot.data?.docs} and then getting this error "the Property 'docs' can be unconditionally accessed because the receiver can be 'null'. How to solve this? Any help?

[@GameplayLeonardo]

Why is my app crashing as soon as I import cloud_firestore package?

[@poor.but.possible]

it may be because of auth firebase depends on core firebase instead

[@GameplayLeonardo]

@@poor.but.possible It was Just cache problem

[@RohsyamSidik]

Thanks

[@ChristianMora]

Hi Guys, How I can get the information and have a text label example: Brand: Tesla sold : 200 Because I'm getting only the data, but I can't put the textlabel (sorry I'm new on this) Thanks

[@rajayogan8884]

Text('Brand: ' + .toString())

[@karthiks1157]

This really helped thanks a lot Sir

[@kumarnavneethbti]

It is not working if we are using Document ID name in place of Document Index like [0] please advise how to retrieve data in the same manner but using document ID.

[@erperejildo]

How could I read a specific document?

[@erperejildo]

You had another vid: kzbin.info/www/bejne/o6vSaWZmh52Cec0. Thanks!

[@carlosseda5619]

Thank you!

[@MikeNugget]

Of course you hide the main part of Firebase initialization without which your app is crashing. And then on the first line in the description you'll see: "Buy my course..". Nice.

[@rajayogan8884]

Haha.. this initialization was stuff that was added to firebase plugin this year. The above Video was made on july 2018, when flutter was still in beta.. also i don't recommend buying my course.. as you can see in my videos for the past one year..

[@rajayogan8884]

Honestly, in my opinion course sellers are ruining the entire developer community on a large scale bro..

[@MikeNugget]

@@rajayogan8884 you are ok, I saw that a lot has changed since you released this tutorial. Anyway, payed courses still take place only in the case of really-really quality content, but in fairness you make great videos on KZbin for free. I am appreciating your work.

[@hugolambert5089]

hello, type=1400 audit(0.0:367405): avc: denied { read } for name Do you have an idea how to fix it?

[@rajayogan8884]

Are you sure you have permissions to read the data on that particular collection in firestore ?

[@hugolambert5089]

im not.. how can I change it?

[@ZachariahZacXAbraham]

Make sure you're in test mode, rather than locked mode?

[@IliveinShadow]

After running the apk I am getting this (The number of method references in a .dex file cannot exceed 64K.) error. I am trying to solve this error but it giving me same error every time help

[@IliveinShadow]

I figure out that error if some one found that error this link will help us just do the same step (flutter.io/android-release/#step-1---configure-proguard)

[@prashantgandhi8822]

how can I pass data to the next screen ?

[@rajayogan8884]

In the same way as you do in any other Object oriented programming language sir.. Have final values in the next screen. Create a constructor to initialize that data.. Whenever you call that screen (by creating an object) pass in the data as parameters to that.. Dart is very much similar to other OOP languages sir..

[@prashantgandhi8822]

can you give me any example .... I want to pass my data from list view to next screen which is fetch from cloud firestore @@rajayogan8884

[@letu9984]
