Please help a newbie 🙏 This allows me to create a value in a database (firebase) but if the editText value is left empty, my app crashes.
Is there a way for me to replace the null value this throws when left empty with a default value like a 0?

val caloriesPerServingEditText = findViewById<EditText>(R.id.caloriesPerServingEditText)
            val caloriesPerServing = caloriesPerServingEditText.text.toString().toInt()

            database.child(addFoodName).setValue(FoodData(caloriesPerServing))

You can use if else statement

[Alex]

will it go where the variable is declared?

val caloriesPerServing = if() else()

toIntOrNull() ?: 0

Check out https://kotlinlang.org/docs/control-flow.html

I'd recommend reading through the kotlin Lang site so you have a better understanding of what your doing

Thank you, I'm still very green

Hi @jefbit sorry for the ping... I tried the following but got the same crash as before

val caloriesPerServing = if (caloriesPerServingEditText.text.toString().toInt() > 0) {
    caloriesPerServingEditText.text.toString().toInt()
} else {
    0
}

[Alex]

thanks a ton for even looking at this... do you see by chance where I'm messing up?

Did you try the suggestion that was mentioned above ?
I belive in your current context it’d look like this:

val caloriesPerServing = caloriesPerServingEditText.text.toString().toIntOrNull() ?: 0
