[urmilshroff]

Implement Bloc architecture as described in this article to improve performance and scalability.

I'd like to work on this issue. Is it still available for working on? thx

Yes, but we've decided to work on it later.

Just to clarify, when I'll be able to work on this? @urmilshroff

[urmilshroff]

@notDmDrl you are free to work on it if you want, but currently there's a lot of changing code that may break things. So we've decided to work on this issue later as switching to Bloc architecture would require rewriting a lot of functions.

@urmilshroff thx for clarification. Unfortunatelly I have like a week of spare time to work on your project and i really want to do it so I probably will start working on it in a few days and will try to make that Bloc pretty easy to add your future code to.

[urmilshroff]

@notDmDrl Oh, okay. That sounds great! Just keep in mind that you follow the CONTRIBUTING.md guidelines properly because of the encryption we've used for our API keys.

Alternatively, you can also work on some of the other open issues if you'd like. Thanks in advance!

Hi @urmilshroff, want to give quick update. So i already have some coding towards Bloc done, i've done some "testing" by launching app (my location was easily found), but suddenly it just stopped working at all. All i get now is error (i never touched this IntroPage at all):
I/flutter ( 3894): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞══════════════ I/flutter ( 3894): The following assertion was thrown building MyIntroPage(dirty, dependencies: [MediaQuery], state: I/flutter ( 3894): _MyIntroPageState#60424): I/flutter ( 3894): 'package:liquid_swipe/liquid_swipe.dart': Failed assertion: line 43 pos 16: 'onPageChangeCallback != I/flutter ( 3894): null': is not true.
I already tried to completely uninstall app, revert all changes to code i made, and even tried downloading project again from git, still not working with exact same error. It also happens on emulator (with both, vanilla and modified projects).

I don't know if i will be able to fix this error today, if not, then i'll continue later this week.

I'm facing that same problem, but in the Driver app. I copy pasted some of the code from Rider to Driver, and while all of it seems to be just fine, that same error is thrown. See this issue.

For me, Rider works just fine as of now. I'm guessing there's something wrong in a recent update of the LiquidSwipe package, so everytime you run flutter pub get on a fresh clone it downloads the new buggy version.

Due to many breaking changes and complexities in code, it isn't really worth switching to BLoC architecture in the forseeable future.

If anybody already has a working solution, then please ping here. Closing the issue for now.
