Bloc pattern in complex scenarios
Hi,Im using flutter and the bloc package for like 4 months now. I think its a great package and design pattern.But also for me there is always this downside in complexity. I dont mean that its not understandable or so but more how something is handled.Its starts always super easy, no dependencies to other blocs, in the "worst case" everything global registered.Then you start to have like different lifecycles for your blocs and reused one bloc with some other services e.g saving things local and at the cloud.Did some one created an open source app that handled this usecase? For me it think im on the right way but its not very obvious like in the beginning.Imagine following scenario:You have list of multiple times IWorkitem with is implemented by notes, todos, drawings. This data is cached in the workitembloc.Now you can click on one of these types of items and view its data and exexute some actions like uodating the drawing or create a new one.Fine then each of the types gets a bloc for the specific details screen which are holding data, calling persist on its service and sends the saved workitem to the iworkitembloc to be shown in the list when you navigate back. But here the problem starts at little bit.You have to pass the bloc via constructor into other ones and with different runtimes it becomes more difficult, sure the one way around is working but not the other. The only thing is left is to compose it in the ui what is really bad. And you returning two states for different screens which Breaks transition animations a little bit, sure its fixable but its effort.I mean its ok, but it does not feel that great how it looked for my simple Apps with some blocs globaly.The thing i learned for sure is, create a bloc for each screen even if you think you dont need it and thats the biggest downside. Bloc feels not natural for one screen one view but maybe its just me, in general i like the package a lot.Thanks for listening to my Story. If someone have some open source projects in that direction it would be interesting to look atSummaryI think the biggest pain is to pass the bloc via constructor and to reprovide it for every route in scenarios where you reusing one bloc even more.It would be so nice if you could mark one path in a tree with a tag and provide blocs and repositories for this Tag. Im thinking little bot on Angular modules and the meta tag annotation you can set on your service where you want to Inject it and not the other way around.Sure there is no modules concept, thats why i made up this "Tag" idea, idk if this is possible even to implement.

MVC vs. BLoC + RxDart ? Does architecture choice really matter with good coding principals and clean design?
I come from a .Net background where MVC is king. So all the MVvM and MVC architectures in the Flutter community are what I gravitate towards doing naturally.Is this limiting me and my apps? I am about to start a new project and thought about stepping out of my comfort zone and trying BLoC + RxDart for the first time cause it's a standard in the community and I've heard good things.Can someone convince me to try this? I still haven't heard a great explanation of BLoC... mostly cause the examples use single variables like an email or bool value(too basic to understand the bigger picture.)

Need help with collecting data for a healthcare Flutter app
Hey everyone. A few of my college mates and I are working on a project that aims to make the quality of life for PD patients better. We are also planning on applying to hackathons to win funds to better support this project of ours. Our idea aims to provide a Parkinson’s Disease symptom assessment tool on a flutter app. This app would allow PD patients to self-assess their symptoms with the help of image analysis by a machine learning model to analyze the severity of PD. The problem we have run into is the lack of data hence the accuracy of our model suffers. We are therefore requesting anyone who can here, to volunteer to collect more data for us by requesting as many PD patients as they can, to take this test on our behalf. This data will be submitted anonymously with the consent of the patient. Please find the google drive link as a comment which consists of a smaller app that we have developed to collect this data. Anyone who volunteers to help us with this needs to get the PD patients to take the tests on the app and send me the result images as a direct chat message without the personal details of the patient. The video there explains how that app is to be used. Please find a presentation file in the drive link for more details on this project. Thank you for taking your time out to read this, especially if you are volunteering to help us in this endeavor.

Best practice for navigating through nulls in Map-ed json when deep nesting (eg, from firestore)?
I've got quite heavily nested json resulting in large trees of Map<String, dynamic>. The structure is known in advance but branches may NOT exist until a later time.In non-nullable dart (not yet released) I can do this:

Map<String,dynamic?> data={}; var r=data['a']?['b']?['c']?['d']?['completed'] ?? false ; print(r); 

This is perfect but probably the firestore libraries will not return Map<String,dynamic?> :'(And nullable dart doesn't support this.​However, with nullable dart I could of course laboriously test for null at each step. To avoid that I use ??

bool isCompleted(Map<String, dynamic> data){ var a=data['a'] ?? {}; var b=a['b'] ?? {}; var c=b['c'] ?? {} return c['completed'] ?? false; } 

Is there a better way?Of course I could optimise with if statements and use parentheses, however I have a lot of these functions to do and don't need to optimise in any case. I'd rather keep them readable as well as easy to write, but I also prefer to avoid all the assignments.
