You can load your json file inside the init method, by using DefaultAssetBundle constructor and passing in the json file path as string, you have to make this await, please google some DefaultAssetBundle json load and you will get your answer.

He's too fast not for beginners like us but he's good

Thank you

@@MobileProgrammer I thought of buying a paid course to learn MVVM but this video just saved my money! Thank you bro. Subscribed!

I m glad my video helped.

Sure. Will do. Thanks for the feedback

You are welcome

Thankyou

@@MobileProgrammerThanks sir! I have a request, Please make more detailed videos on proper Flutter architecture using provider that can be used in large apps as well i.e scaling at big level is possible. And also the folder structure that we should follow. Thanks again for your efforts

Not necessarily,most of the times apps will have multiple notifiers to separate the logic in different files

@@MobileProgrammer It's been 6 months since it started. I collected the vms in main like you, but since there are more than one it's wrapped with all vms in the widget tree. I don't know if this is true.

async improves your apps performance no matter if it is a network call or not. when you call a network function with async, the network library is doing the real async call, not your function that is actually doing async network call, I hop you get it.

I will try.

You can definitely do that. What is blocking you? So basically you have to modify and update the data and add to user list or so

@@MobileProgrammer I just try to find the best solution from design perspective. First thing that comes to my mind is to have a method updateEmail(String email) inside the UserModel class, and then to call it from the ViewModel via _selectedUser (i.e. updateSelectedUsersEmail(String email) { _selectedUser.updateEmail(email); notifyListeners(); }. Is it a good practice to have methods to edit Model values inside the Model class? And if more general - I try to understand how to handle nested objects - imagine you have list of Users, each user has list of settings, and each settings has list of something else - and you want your app to allow going deeper down the tree and edit the values - the above described approach can get messy (i.e. we should have _selectedUser, _selectedSetting, _selectedSmth etc.) - so I am wondering if this can be managed by one ViewModel or should we also have nested ViewModels to deal with this kind of problem (and if Provider can handle nested ViewModels)

Logic should be inside the bloc event driven

Yes, please check description

Please check the repo in the description

You can find it at the end of written tutorial in the description

I forgot to include in video.. please just create a class

Sorry buddy. I was busy

You can find it in the source code link I the description

@@MobileProgrammer where is it?

@@karthikm7063 Thanks for your support.

@@buraksafak9107 welcome

please check the description

It’s not fancy name. You heard view model first.

Plz check the description

Navigator.push

@@MobileProgrammer how to navigate for the particular user

Same

@@MobileProgrammer can you make a short video on that please I'm not getting it

I wil try

What is the error you are getting?

Well, object has to held somewhere, so it would be in view model

But this object will be there in the viewmodel even after got back from the screen which uses the object

Lets say we have 30 screens and 30 viewmodels , how can we release the memory that all of these objects occupied when these are not in use

You can override the close method in the bloc to dispose anything

A view model does not correspond to a screen first of all. So that would be a bad design. You can have one view model for the entire app also. You can clear data anytime you want.

Please check the source code linked in the description

@@MobileProgrammer Hi, I can't fine the link to de Source code. Where is?

@@MobileProgrammer can't find a link for this repos,please send it here.I really want to understand mvvm for flutter

@@MobileProgrammer have you delete your article on medium? i can't find your article

No. I didn’t

Yeah, I forgot. Will add in the description. Sorry

@@MobileProgrammer Thanks

Sorry, I might have missed it. You can find it in my repo which is linked in the description.

@@MobileProgrammer I don't see users_error in your repository.

Sorry, I might have missed it. You can find it in my repo which is linked in the description.

@@MobileProgrammer okay that's fine.

@@MobileProgrammer where is the link sir plz?

Just create a class . I forgot to include it in the video. Sorry

Just assign some value to the variable before using it if you have declared it using late keyword
