What have you tried so far?
lv_obj_set_style_local_bg_color(arc,LV_ARC_PART_INDIC, LV_STATE_DEFAULT, LV_COLOR_BLACK);
Code to reproduce
Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.
The code block(s) should be formatted like:
static lv_style_t style;
lv_style_init(&style);
lv_style_set_line_width(&style, LV_STATE_DEFAULT, 15);
static lv_style_t st_color;
lv_style_init(&st_color);
lv_style_set_line_width(&st_color, LV_STATE_DEFAULT, 15);
//
lv_obj_t * arc = lv_arc_create(lv_scr_act(), NULL);
lv_arc_set_bg_angles(arc, 0, 100);
lv_arc_set_value(arc, 50);
lv_obj_set_size(arc, 230, 230);
lv_obj_set_style_local_border_opa(arc, LV_ARC_PART_BG, LV_STATE_DEFAULT, 0);
lv_obj_set_style_local_bg_opa(arc, LV_ARC_PART_BG, LV_STATE_DEFAULT, 0);
lv_obj_add_style(arc, LV_OBJ_PART_MAIN, &style);
lv_obj_add_style(arc, LV_ARC_PART_INDIC, &st_color);
lv_obj_align(arc, NULL, LV_ALIGN_CENTER, 0, 0);
Screenshot and/or video
If possible, add screenshots and/or videos about the current state.
