Getting value of ItemInput

[Angenieer]

Hi! First of all, thank you for this great library!

I can't figure out how to get the value of the ItemInput object. I've tried this:
MENU_SCREEN(pendienteScreen, pendienteItems, ITEM_INPUT("Pendiente:", [](char* value){ // }));
in the loop:
1)
Serial.println(pendienteScreen[0].getValue()); //Serial.println(pendienteScreen->getItemAt(0)->getValue());
Or alternatively:
pendienteScreen[0].setValue("test"); //pendienteScreen->getItemAt(0)->setValue("test);
and I get the following error: Compilation error: 'class MenuItem' has no member named 'getValue'.
I've also tried:
2)
pendienteItems[0]->getValue();
getting the same error: Compilation error: 'class MenuItem' has no member named 'getValue'.

I can't find neither and answer in other discussions nor an example code in the wiki, in order to solve the problem.
Basically, I'm not understanding how to reference to the object ItemInput. Sorry if it is obvious, i'm a beginner with C++ and Arduino. Thanks!

You will need to do a static cast, if you're certain that the item at index 0 is indeed an ItemInput

static_cast<ItemInput*>(pendienteItems[0])->getValue();

Also worth looking at the SimpleInput example

It worked! Thank you!
I have another question. Is modifying the value of an ItemInput the best way to print a variable on the LCD? This is what I want:
pendiente: N
where N is the value of the variable I want to display on the LCD but I don't want any input from the user. So is there a better way to do this?
