Should I learn Dart before diving into Flutter ?
Hi. I'm a first year computer science student from France. I heard about Flutter not that long ago while searching for cross-platform developing tools and now I want to learn it and use it as it seems to be a great tool and maybe demand will be there when I graduate. But I don't know where to start. I know a bit of python and I am familiar with the very basics of OOP, not much else. So, should I learn and be confortable with Dart before exploring Flutter ? Thank you to all.(Sorry for long post and probably broken english.)

What can i use in a <fill in the blank>
Hello, I am currently taking a Udemy course for Flutter. I am 30% in and have come to a point in the course where i have to build my own app. I type in "container" then proceed to use a row, but i cannot, i tried using a background image, nope, i then tried to do something with a text.. I seem to not know exactly what is available for whatever widget I'm working on. How can i see what widgets are available to be nested into other widgets? I know this might sound lame but, I'm just not retaining something. Also, are these widgets called attributes?Frustrated

How do I get my button grid to scale to the size of the container?
The problem I'm having is that we are trying to get a number entry grid like this, but we cant figure out how to get the buttons to auto size so they both a) have the margins I want between them, and b) fit the width of the container and the other elements in the container.we are using column's mainAxis.spaceBetween but so far all we have managed is hard coding the buttons to size thembasically how would we make this so it scales right to different devices will still keeping the nice margins and alignment (outsides of buttons align to submit button edges, and all horizontal and vertical margins are the same size)thanks! we have been falling apart over thisedit before posting: we may be trying a table class?

Navigator side-effects and route guarding.
I'm starting to refactor a Flutter app and I'm trying to divide concerns better between the app's Widget(s) and it's business logic.I was wondering if some of you have found some pattern to solve two isolation problems:The first is starting asynchronous tasks (like start and API call or a DB read) when a route is pushed without the page knowing about this side-effect.The second is route guarding which is basically disabling (or redirecting) a route push if some condition is false or resolves to false (Future<bool>). For example some pages of my app should be visitable only if the user is authenticated and I'd like to redirect to a sign-in (-on) page otherwise.I'd personally solve the first one by using an entity that implements RouteObserver and dispatches the tasks when a specific route name is pushed. I do not want to just dispatch it before the WidgetBuilder provided in the routes parameter of MaterialApp returns its widget.​For the second one I'm not seeing a better solution than wrapping the Navigator in my custom implementation however this would make my app pages depend on this non-standard Navigator and I'd like to avoid that.​I'd like to discuss alternatives to these solutions and possibly reason about possible pitfalls.

Display a status update page if user has data
Hi all,Basically, a user registers and create an account, the sees the current status of the submission he made 'submitted'What I want is that next time the user login, I would check if the user has a document/collection in firestore, if he has, he his taking to the application status page,But if he doesn't have, he is taking to the beginning to fill the form.So I guess my main question is how do I check if he has particular document in firestore.FYI: my data model is ...... Collection ('user'). document(user.uid). collection ('update')....So basically I want to check if a collection update exist?, Each time the user login.
