Hi @greensopinion any clue about this?

greensopinion commented 3 weeks ago

a couple of ideas:

  1. have a look at your theme, and compare it to a theme that is working (what's different)
  2. consider running in the debugger and set a breakpoint in some expressions https://github.com/greensopinion/dart-vector-tile-renderer/tree/main/lib/src/themes
