Problem
I have a button with circular image, with the image in the ratio 1: 1, and when executing the code (below) the program generates a screen with aspect ratio of 1: 1, but it is possible to resize the screen and change its aspect ratio and size, however, the image does not grow together like the screen and takes up a smaller proportional space. I've tried setting values to size_hint: , but it distorts the image, except in a single ratio. How can I make this button adaptable in relation to any proportion and size, without distortion and with the same proportional space?
Screen generated (1: 1)
Resizedcanvas(16:9)
