BLoC Library - Learn how to use the BLoC pattern for state management

[Copied from https://github.com/felangel/bloc/issues/4002]

I've recently ported my project to BloC and I used the BloC infinite scrolling example as a blue print for fetching data from my FireStore repository.

Architecture: Repository pattern as described on bloclibrary.dev

Vs Code has this extension, that can generate all boilerplate code that you need, and everything about bloc has been documented right here. Take a day or two, to familiarize yourself with the examples.

Looks solid, congrats! This is probably a huge ask but, flutter_bloc has this repository of examples covering almost every imaginable use case. Would be really great to have something similar. Check it out > https://github.com/felangel/bloc/tree/master/examples

From this issue on the bloc package :

Check out https://bloclibrary.dev I think they do decoupling the best

https://bloclibrary.dev taught me a bunch

We want to position the child widget on the line, which cuts a given slice in half. To achieve that, we start of with a vector that points to the center of the top edge of our bounding box starting from its top left. This ensures that the vector's length is half the circle's radius. To actually point to the center of our slice, we need to rotate this vector by half the slice's angle, which gives us the blue vector in above illustration.. If you are interested in how the rotateVector works, you can find its implementation in this package's Github repository. With the slice's center at hand, the child's offset can be retrieved by adjusting the center to the child's size. If you believe there is a simpler way to achieve the same result, I encourage you to send me a message or comment with your ideas about this problem; I am always glad to learn of new features and tricks.

Great! We are now able to draw a circle composed of any number of individually customizable slices. In my next article we will implement a MultiChildLayoutDelegate to correctly position child widgets within the slices. In the meantime, if you don't want to wait for the next article, you can find the package's code on Github.
