That's unbelievable.
I'm working on a project using Flutter, a framework made by Google.
And of course, as every product of Google, is full of bullshit.
I was creating a theme for this app and I had to styles some texts. I whis I never tried it.
There's a plethora of attribute: headline, body, title, ecc. For each of them there are many types: headline1, headline2, headline3 and so on.
So I checked the documentation, because of course i had no clue on which one I should have used.
And again, the documentation is made by Google: full of bullshits.
They don't event tell you which one do what. So now the best thing to do is to create an entire project just to figure out what the fuck each of them does.
