How to set min size of a button through code

Question

I am trying the generate a list of buttons in my code and display them in a VBoxContainer, but the buttons get resized to the default size of 20, not the size I give them. I have looked at other similar questions and they say to use the rect_min_size function but I get an error saying Invalid call. Nonexistent function 'rect_min_size' in base 'Button'.

My code so far:

extends VBoxContainer

func _ready():
    for i in range(Stats.button_list.size()):
        var button = Button.new()
        button.set_size(Vector2(125, 40))
        button.rect_min_size(Vector2(0, 40))
        button.text = Stats.button_list[i]
        button.show()
        add_child(button)

Answer 1

rectminsize is a property, not a function
does setting the value work

button.rect_min_size = Vector2(0, 40)
