    "unhandledError" listener?

    in General questions
    Hey guys!
    I watch recent video (in russian language) about mailgun.com error reporting from corona app. It's very primitive, yet pretty handy.
    https://github.com/bogomazon/corona-mailgun

    When unknown error occurs, app sends email via mailgun api, and player sees popup before app crushing.

    How can we show this popup to user before app crush?
    I see that in corona it's made using event.unhandledError, how can we detect such event in Gideros?
    Thx!
    local unhandledErrorListener = function( event )
    print( "We have a problem: " .. event.errorMessage )
end
 
Runtime:addEventListener( "unhandledError", unhandledErrorListener )

      Assuming we are dealing with lua errors, you can just wrap your code inside pcall() and handle errors from your code. Gideros does this too but don't send events. Maybe that can be added somehow to gideros.

      function f ()
  return "a" + 2  
end -- f
 
function err (x)
  print ("err called", x)
  return "oh no!"
end -- err
 
print (xpcall (f, err))
      ще варіант
      function myfunction(x, y)
...
  if ... then
    error("failed to do somthing")
  end
...
end
 
status, err = pcall(myfunction, x, y) -- f:функція, x-y: її аргументи
if not status then
  -- опрацювати помилку err. в err знаходиться текст помилки "failed to do somthing"
end

      But we have lots of functions in our projects, it's sort of inconvenient to pcall every single one of them?
