How have you been implementing cross platform UI?
I am writing an app in flutter and starting to think about how I will handle Android and IOS ui's. I have some questions about how people have been doing their UI's.Do you you have separate UI from the ground up with for each platform (eg. separate screen/Top level widget classes and everything)?Or do you have more a more granular implementation where the UI might share the same screen and some components, but some parts of the screen/UI are platform specific.Or do you just try to write one UI where it is not native looking on one or both of the platforms?Thanks!!

Proper state management across routes
Using a TODOs app as an example, imagine you have a simple app with a list of TODOs displayed on the main screen, as well as second settings screen. In the settings screen, say you have a setting to that changes whether the text of each TODO is displayed in uppercase or lowercase.I can imagine a couple different methods that to achieve this:When pushing the settings screen, you could await the Navigator for a result. The settings screen must pop the Navigator with a result and the main screen interprets it and updates its state accordingly.Pass a callback to the settings screen which the settings screen calls when it updates the setting. The main screen rebuilds itself when the callback is called.(Similar to #2) Using the controller approach. For example, have a ValueNotifier<bool> in the main screen that contains the true/false value of whether or not to capitalize the text. The main screen uses ValueListenableBuilder as a parent to the ListView so it is rebuilt when the value changes. Then pass the notifier to the settings screen and when the settings screen updates the notifier, the list will rebuild.Use RouteAware on the main screen. When the navigation returns back to the main screen (onPopNextRoute), check if the setting is now different and rebuild if so.My problem is that none of these solutions seem good to me or I don't know which is best. Or maybe I'm missing something else.Solution #1 seems like the proper approach in that it waits for the settings screen to be finished and then you can determine whether to rebuild. But this seems like it would not be good with more complex routing. Like if the settings screen could navigate to other screens which might return back to the main screen. Ensuring the proper result is returned to the main screen sounds like it could get very tedious.Solutions #2 and #3 have the problem where updating the value on the settings screen will cause the main screen to be notified and rebuilt even when it is not being displayed to the user. Sure Flutter might be efficient but this just feels wrong. Or am I wrong to worry about this? I worry more for a larger app with many screens. Imagine updating a setting that rebuilds many different widgets on previous screens. Also, passing the callback/notifier around could get tedious with additional routes as well.Solution #4 seems okay, but it means caching each setting's previous value and comparing for differences, even if they have not even been touched in the settings screen. This approach is not one I've seen anyone else really use so I'm not too confident about using it even though this is what I'm currently using in my real app.

Which course should I do next?
Hi Flutter devs,I've made a few flutter apps by now, but i feel that some structure is missing in them (and still have a few problems scaling sometimes) and I would like to do a course that would teach best practices. From what I have seen, people suggest the following:https://www.udemy.com/course/flutter-bootcamp-with-dart/https://www.udemy.com/course/flutter-firebase-build-a-complete-app-for-ios-android/https://www.udemy.com/course/learn-flutter-dart-to-build-ios-android-apps/If you have done any of all of this, which do you believe to be the one that makes you more "industry ready" ?Thanks for the help!

Open-Bonfire source code
As for the last weeks, I was updating a project I worked on to learn advanced Flutter.This app is quite simple, you create a post at a geographic location and your post is only available at this location. There are daily quests that give experience at completion or penalties at failure.The big challenge during those last weeks was to be able to run background tasks with BLoC state management. It works but I am aware that big improvement can be made performance-wise.The entire source code for Bonfire is available here. If you want to see the app in action check out the Google Play page.Disclaimer: The project is quite big, it may not be suited for complete beginners. Disclaimer 2: The code can be very messy at times (I was bored or something).
