I want to draw/fill a circle on a container and draw a rectangular (with transparent filled ) .
How to create them ?

Thank you.

You can use lv_canvas_draw_rect and customize the properties of the style. For example, to draw a circle you would set the border radius to LV_RADIUS_CIRCLE (or something along those lines).
