Sorry for the late reply.
Very relevant point. Indeed, this is something we are still thinking about. The
main thing we focused on was to have the attributes as objects first, and then
an API that is easily extensible. The fluent API comes on top.
At the moment, we tend to favor a builder approach that goes in this direction:
text attributes textSize: 60.
The issue is a bit of a more general concern as we already have the same need
in several places in Bloc and we already use a builder pattern. For example:
BlKeyCombination builder alt; control; key: Key c; build
BlBorder builder dashed; paint: (Color green muchDarker alpha: 0.7);
However, these two are for creating a new instance, while in the text example
we have to deal with modifying an existing one (i.e., the text). Decisions,
decisions … :)
