Support Dart-only dependents

Package

google_fonts

Description

My dart server has the function to create the pdf file but my Thai language doesn't support it with the default font on the pdf package. Then I want to use the font from this package.
But it looks like this package doesn't support the Dart server side.
I got this error after running the server.

/C:/Users/user/AppData/Local/Pub/Cache/hosted/pub.dev/google_fonts-4.0.3/lib/google_fonts.dart:7:8: Error: Dart library 'dart:ui' is not available on this platform.
import 'dart:ui' as ui;

Context: The unavailable library 'dart:ui' is imported through these packages:
