Flutter State Management: Going from setState to Freezed & StateNotifier with Provider

[@nipunmadan1989]

This must go on official flutter channel. Complex topic explained easily.

[@dantong8934]

Thanks for the tutorial. Very easy and deep understanding.

[@aloussase]

Im not sure when sealed classes came out, but today id think that is the way to go for modeling state

[@ilmtvtamil]

why google didn't hire you yet?

[@alejandrogonzalez5192]

Hey Andrea, thanks for the tutorial!
Would you suggest going for Freezed + StateNotifier for a production app?

👋🏻 Andrea! Thank you for this tutorial.
At 14:26, I needed to import 'package:flutter/foundation.dart' at the top of the file to make the command line generate the .freezed file. How could it work for you without it?

thank u

How can a single StateNotifier class produce two/more different states?
Or do I just need the same number of StateNotifier classes for each state?
I'm stuck with this problem for around 3 days. Still stuck!

[@ericchua3492]

I need some help.
What if the behavior is this
i. Load Profile if any
ii. Edit Profile
How do you construct the ProfileState and ProfiileModel? I am struggling to have both Load and Edit in the same StateNotifier and how to manage the State (freezed).
The unexpected behavior
i. load profile
ii. tap on save
iii. profile saved
iv. profile is hidden (profile is already loaded, why can't it stays on the screen??? )
my state freezed as below (not sure should I combine or mixed)
@freezed
abstract class EditProfileState with _$EditProfileState {
// General
const factory EditProfileState.error(String errorText) = _Error;
// Edit
const factory EditProfileState.loading() = _Loading;
const factory EditProfileState.success() = _Success;
// Load profile
const factory EditProfileState.dataInitial() = _DataInitial;
const factory EditProfileState.dataLoading() = _DataLoading;
const factory EditProfileState.dataLoaded(User user) =
_DataLoaded;
}
Do you have any sample codes to achieve the above? Thanks.

[@CodeWithAndrea]

I would think the states you need are:
- noData
- data(user)
- loading
- error
Maybe you should load the initial data from your DB before showing the profile page? Then you can initialize your initial state with noData or data(user) accordingly.

[@ericchua3492]

@@CodeWithAndrea if i want to edit the profile, upon success which state will it be? data (user) ?
