Nice video! Helpful. Can you show how to read a Firestore collection and then assign it to the List as you have in your video? Firestore doesn't have the ability to search fully. This is a good alternative since my dataset is relatively small. Thanks.
thanks.. but in class Debouncer, Debouncer({required this.milliseconds}) line gives an error method saying to initialize timer and action ?.. tried different options but no way..pl. suggest what to do
Thanks for awesome video . I have a question we have a ListView.builder that get data online to show , if we have another screen too and get data from user manually , can we show those details inside this lisView too ? i mean when we have a list view can get data from two different part and show in one listview ? if yes how ? Thanks a lot
Great tutorial! But can't get the VoidCallback to work. What class/package do you import the VoidCallback from? Because I have different options to select.
I like the tutorial but when we added the Debouncer I started getting an error related to: _timer ERROR LateInitializationError: Field '_timer@22438464' has not been initialized. I think it's because of null safety, but initializing late Timer _timer; doesn't work Do you have a suggestiuon to fix this error please?

@@MobileProgrammer thank you again.i tried and it worked watching your tutorial. If we have multiple parameters fetched from the database can we pass all parameters like a list other than passing each parameter like detailpage( whole list) . Any idea?
@@MobileProgrammer By the way, the SearchDelegate has a bug when I was trying to implement it. I need the search feature. I thought SearchDelegate is the answer but it ended up having a bug in web mode on Android. Hence I was searching and land on your video. My cases is little complicated. I have two level of Streams. But I got what you meant, I will try that option but my search result will lose the stream behaviour.
@@MobileProgrammer Do a flutter build web. Then deploy the app somewhere. Then open the app in Android, on any browser. Try to do your search 3-4 times. Boom, it does not work.
Open your main.dart file and add this file as the Home of the material Widget. Since it is basic and present in every project, I didn't show in the video.

jessy, I didn't show the mail function, when you create the app, main function will be there in the main.dart file. Simply add your class there in the 'home' property.
Your My Hero for me
u are the besttttt maiii freeen!!!!
Cool!!! Worked! Thank you!

Thanks a lot
Yes it’s possible. Get the data from two sources and make it into one array, assign this array as data to the list view.
@@MobileProgrammer thank you so much for your kind response , you are awesome
Great tutorial! But can't get the VoidCallback to work. What class/package do you import the VoidCallback from? Because I have different options to select.
There is no special import for VoidCallback. Did you import the material package.
@@MobileProgrammer Thanks, I solved what I was doing wrong. Everything works perfect. Great tutorial and thanks for the reply!
brother how to filter firestore data like that with futurebuilder
I like the tutorial but when we added the Debouncer I started getting an error related to: _timer
ERROR
LateInitializationError: Field '_timer@22438464' has not been initialized.
I think it's because of null safety, but initializing late Timer _timer; doesn't work
Do you have a suggestiuon to fix this error please?
I have a similar error
You can make the timer nullable when declare. But make sure to initialize before using it.
Thanks for the tutorial, but could you make one, with online search not local, thanks
Sure. Will do that
@@MobileProgrammer 🙌👍
Thanks, do you have the source project?

@@MobileProgrammer thank you again.i tried and it worked watching your tutorial. If we have multiple parameters fetched from the database can we pass all parameters like a list other than passing each parameter like detailpage( whole list) . Any idea?
You can just send in the constructor
Nice, how can i do this with not showing any data in the listview at first?
Check this video. This has similar implementation of hiding views . Basically u just need a Boolean variable and show view only on true.
@@MobileProgrammer which video?
Hello, Please how do i filter from a database?
You can write a select query in the database to filter your values from the databases.
how to do that with offline json data
How to use this in local json file?
How do we do it with StreamBuilder, where each component loads one by one and you dont have a full list in hand to work with.
You might need to wrap listview inside a streambuilder and get data from the snapshot whenever stream is triggered
