This required refactoring the code. With this we can now write an
integration test to test the main parts of the app, but more importantly
we can automate the process of generating the screenshots.
For now I've mostly tried to follow the same style guide as the flutter
repository, with many options disabled. Eventually, maybe it would make
sense to be far stricter.
This way it properly aligns up with the hamburger menu.
I also discovered this 'debugShowMaterialGrid' option which makes
working with padding issues much much easier.
It's annoying, and does not allow us to easily take screenshots.
Specially since the apps built in release mode cannot be run in an x86
android emulator.
For now just create a local git repo and commit all the changes over
there, we're going to allow the user to first see the app and use it
however they want, and later connect it to a remote git repo.
This commit breaks the app, as the on-boarding screen is no longer
connected so you cannot push to a remote app.
This simplifies the code quite a bit, at the cost of using this
strange flutter magic of an 'InheritedWidget'.
It basically make a class a global variable.
