How to make Labels in RecycleView change size according to texture size during runtime?

I have a RecycleView which consists of labels and a MDSlider which I use to change font_size of those labels during runtime. I'm wondering if it's possible to align labels' size to their texture_size property. Precisely, whenever I change the font_size which would cause label's texture_size to overflow its current size, I would want to increase the label size so the text fits. Since labels live inside the RecycleView, I'm not sure how should I approach the problem. I'm initially setting height to self.minimum_height of the RecycleBoxLayout which I presume should be updated in the process. I noticed that I can manually change the RecycleBoxLayout's default_size during runtime, but not sure how exactly I should pass the texture_size of the label to adjust the size. I tried with on_size and on_texture methods to pass the property and use to calculate default_size, but things get really complicated and I always end up getting gaps between the labels. Ideally I would want the solution that uses some kind of binding of labels sizes/texture (similarly like I already have with the app.fontSize) so I would get automatic resizing because any manual calculations of RecycleView properties and it's consequential update significantly slows down my program in the end when testing on Android.

Any ideas?

EDIT: I haven't mentioned it, I'm only interested in the height resizing. Width doesn't matter.
