I've got a lot of help from your videos and suddenly realize I've never made comments. Thanks for your works.

[@FunwithFlutter]

I’m glad they’ve been helpful to you! Always great to hear

[@barindersingh04]

Amazing video thanks!! waiting for riverpod provider listener video

[@iangriggs]

Great series on Riverpod. You are filling in some important gaps in real world usage with these videos. Please do the next Riverpod update with Freezed (or a dedicated video on Freezed anyhow?) or maybe Firebase auth with Riverpod StreamProvider?

[@FunwithFlutter]

All great ideas. Yeah I think Firebase would be a good example of using StreamProvider. I'll probably do a Freezed video and then the stream provider one.

[@cptsakamoto]

Thanks for the video.

[@shannonhall4871]

Fantastic content brother, I appreciate your effort.

[@FunwithFlutter]

You're welcome!

[@user-wr9ff4wl4o]

Big thanks!

I tried similar concept of toggle in my code. It is still refreshing and updating state of all models in the list.

[@tadaspetra]

Great video! Really great way to handle it. Quick hint, I am pretty sure at 18:59 you are unnecessarily unpacking a list into a list. [...list]..add should work the same way as list..add

[@FunwithFlutter]

Oo thanks for that :)

[@tadaspetra]

@@FunwithFlutter yea I think that’s right!

[@officialismailshah]

you are awesome ❤❤❤❤🙌🙌🙌🙌

[@FunwithFlutter]

Stahp 😊

Wow Aweasom tutorial ! thank you so much, if you can make another tutorial how to use ' State Notifier with AsyncValue & Handling Exceptions' to make things more clear that will be nice thnak you

[@FunwithFlutter]

Maybe I'll do a bigger app from scratch using Riverpod. Start to finish

[@frederickmfinanga2037]

Hey, unrelated but could you a flutter web video on how use firebase email link sign in?

[@findsarfaraz]

Want to know if you are handling a error in function inside the state notifier and you want to update error to user or prompt user about the same. How would you do that. Will it also require the exception provider which will be updated same will handled via ref.listen in UI.

Hello, my question is make reward app with flutter is possible? or make reward app is the field(=realm) of native app(kotlin, swift)? (reward app = if user watch advertisements, they can get real cash and i get ads commission)

[@TechWithDnes]

Wow... Nice ))

[@FunwithFlutter]

Thank you! Cheers!

[@findsarfaraz]

Sir, when you are using AsyncValue in statenotifier when you toggle completed using the function. Will it rebuild only one tile which is changed or entire list. I am facing this issue. I am not able to run your code so far.

[@hasan_eke]

read(todosExceptionProvider).state is not working

[@FunwithFlutter]

There has been updates, you no longer need to do .state. You get the state back automatically. But to get the notifier you will need to do read(provider.notifier);

[@burakbirer5938]

This is quite complicated.

[@FunwithFlutter]

Oh no.
