Flutter performance for a big scale Android App.
I am planning to make an app using Flutter for a client, it is seemingly a long project and the app is basically a Learning app with a subscription model.I want to know if choosing Flutter would result in significant performance trade-offs down the line.Typically the features I'm worried about are:- Video playback with play/pause. Storing time of video played till now and starting from that spot in subsequent plays.- Infinite growing lists with images.- An integrated timed-test with focus on time spent on each section, and on multiple sections in different tabs.- Display a sort of learning material in app (something like a notes section which includes diagrams and explanations related to study videos)I don't want to give time and resources to this project and later find out that the performance penalty is too severe for it to be a viable app.Appreciate any advice (btw the app will mostly be Android only, however if you could also let me know about performance in iOS)

What is the reason behind using barrell files?
I have seen a couple of tutorials using the "barrell file" which includes all of the imports of a certain folder. However, I don't see any reasonable advantage of using it since all the imports are managed by the IDE (Android Studio in my case). My IDE also displays three dots instead of all the imports so I don't care about the number of imports.So why use the barrell file? Am I missing something?

There is another way of navigation
In 2020, flutter team announced the declarative way of navigation, but just after its release a lot of bad reviews came out from developers from all over the world saying it is too verbose process to implement navigation using navigator 2, BUT, if we just try to understand the process of using navigator 2, then the power that flutter provides with navigator 2 can help us achieve great navigation flexibility in very simple way. After understanding and implementing the navigator 2 on few Projects I found it to be a game changer for any app.In the article, I tried to explain the concept that one needs to know before using the Navigator 2.0. The link of the article is on the first comment of this post, I hope you guys would find this article helpful.Let me know your thoughts on flutter's navigator 2 on comments below.Thanks

Handling errors with ChangeNotifier.
I use ChangeNotifier to maintain state, and update my UI when this state changes. I am curious how other handle errors when using ChangeNotifier.For example, lets say I have a ChangeNotifier that handles signing in a user (simplified for this example).The states it can be in are as follows....State.noUserState.signingInState.hasUserThe method that can be called on it is...signIn(email , password)When I call signIn , the state transitions to 'signingIn', when signin it complete, the state will transition to 'noUser' or 'hasUser'. But if the signIn fails, I have to communicate an error. I see two options to do so, and I am curious what how other people solve this problem.Option 1: Add a new value to my State enum called 'signInError'. The only reason this feels off to me, is because I need to create a brand new method just to transition out of this state..For Example, I might create a method called clearError() that will transition the state back to 'noUser' after an error has occured. So if I show an error dialog, dismissing it would called clearError() on the ChangeNotifier. This has code smell for me, but I am not sure why.Option 2: Have all method calls to the ChangeNotifier have a success/error return value. In the simplest implementation this could just be a bool that represents success/failure. That way, the State of the ChangeNotifier stays clean.....it represents the current user state an nothing more. But on the downside, now there is more state that will be pushed to the UI. The UI will have to handle this bool return value, store it in a variable in a statefulWidget, and then call setState to display some error UI dependant on this bool.What are peoples thoughts on this problem? How have you handled it? Have you found any particular state management solution better or worse for handling this problem?
