How to get id of tapped button.

I need to know which button was tapped. I think id should be used - I don’t know.

That’s what I have:

local function addItem(event)      if("ended" == event.phase) then          --[[IF ID == ... THEN --]]      end end local addBtn = widget.newButton( { top = 170, width = 70, height = 70, id = "addBtn", defaultFile = "", onEvent = addItem, defaultFile = "add.png", } )
#2 
local function addItem(event) if("ended" == event.phase) then if event.target.id == "addBtn" then end end end
#3 
local function addItem(event) if("ended" == event.phase) then if event.target.id == "addBtn" then end end end
