I noticed that the SDL keyboard driver (lv_drivers v8) it implements the keyboard to be used as keyboard/text entry input for lvgl.
In one of my projects I dont have a keyboard but I will have keys that needs to be mockup.
So I would need to change the SDL port implementation.
My suggestion would be that it may be added some callback to handle the SDL keyboard entries and returning true/false if the key was handled.
This way maybe I can use directly the SDL lv_driver branch without changes.
