I have developing a app based on LVGL 8.3.3, using the editor SquareLine Studio 1.3.4, and the code generated is compiling by Arduino 2.2.1, the problem is using a external library (WiFi.h) in a event. I tried everything, insert the include <WiFi.h> in several files like (ui.h) (ui_events.h) (lv_conf.h), main INO file.
but compiling with Arduino always jump the next error:
