Hi Ramon,
It is already fixed in dev-5.0 branch but if you update you need to do other changes as well (see dev-5.0 doc/README).
For now, I think it would be easier to fix the issue in your current version. You only need to change area_t area; to lv_area_t area;

I hope that is all.

On Monday I can send you a .zip (like before) with the new version

from lvgl.

Here is the new version. lvgl_dev-5.0_arduino.zip

Please follow the updates in your initialization.

Now only disp_flush is required (same as map_fp) but lv_flush_ready(); need to be called at the end
lv_tick_inc(1) is used instead of lv_tick_handler()

#include <lvgl.h>

void my_disp_flush(int32_t x1, int32_t y1, int32_t x2, int32_t y2, const lv_color_t *color_array)
{

  /*Write the coordinates like with disp map*/

  lv_flush_ready();
}

void hal_init(void)
{
    /*Initialize the display*/
    lv_disp_drv_t disp_drv;
    disp_drv.disp_flush = my_disp_flush;
    lv_disp_drv_register(&disp_drv);

    /*Initialize the graphics library's tick*/
    /*In a Timer call lv_tick_inc(1) in every milliseconds*/
}

void setup() {
  lv_init();

  hal_init();

  lv_obj_t *label = lv_label_create(lv_scr_act(), NULL);
  lv_label_set_text(label, "Hello Arduino!");
  lv_obj_align(label, NULL, LV_ALIGN_CENTER, 0, 0);

}

void loop() {
  // put your main code here, to run repeatedly:

  lv_task_handler();
  //delay_ms(3);
}
