ah, sorry. It's actually a slightly different problem. I also didn't find an easy solution. But I use TextDelegate to render 2 lines, then render only the second line on a Canvas

lineHeight doesn't work as expected for some reason for the first line, that's why you need 2 lines

I used • TextDelegate to layout 2 lines of text: first - empty, second - actual text • ParagraphStyle to set lineHeight=1.sp in annotated string. •

translate

function within Canvas to "hide" the first line. LayoutResult gives you baselines, lines' top/bottom coordinates
