Issue
I’m creating a text-style model and using getter to have the text-Style that use google_fonts. The issue occurs when I provide fontWeight: property. Also, the fontWeight is not providing similar look as GoogleFont.
I’ve tested on another project, rebuilding the project, using html renderer. I’ve checked this question but it is not working.

Solution
Only certain fonts support one ttf file with different weights. If you notice the alphabet g it looks different in each weight. You may have to download the full font family from Google fonts and include that in your pubspec.yaml under assets. It should work.
Check https://pub.dev/packages/google_fonts bundling font in application assets section.
