Gnome 48 (from March 2025) switched its default font from Cantarell to Adwaita Sans: https://blogs.gnome.org/monster/introducing-adwaita-fonts/.

This PR adds Adwaita Sans to the Linux font fallbacks list: Adwaita Sans will be used instead of Cantarell if available.

Adwaita Sans is a slightly tweaked version of Inter, and therefore fits in with Roboto and the rest of the Linux font stack.

Code Review

This pull request adds Adwaita Sans as a font fallback for Linux, which is a necessary update as it's becoming the new default font for GNOME. The changes are applied consistently across the C++ engine, the Dart framework, and the corresponding tests. The implementation is correct. I have one minor suggestion in the test file to improve maintainability by reducing code duplication.
