I need help with AutoFontSize

I'm creating a mini-project for around 100 people, each with a different model of cell phone. When I display a font on each phone, it looks different due to the size (the difference in width and pixel density). How can I unify everything? Is there an extension? A formula? I'm stuck on this part of the development, as I haven't found an extension and I've used formulas that divide the screen width by a certain number, but it's only a partial solution.
P.S.: I apologize in advance for my English; I speak Spanish, so I'm communicating through a translator. I would appreciate any help.
Thank you very much.

@Ferran_SIMON You've had some experience working on multiplatform apps. Do you have any advice here?

If you can't fix it, make it a feature.

Add a Settings feature to the app where users can set their own font sizes.

Post some screenshots so we can get an idea of ​​what it should and shouldn't look like. And let us know on which devices.

The font size setting in the device settings is, of course, unpredictable. After all, some people have poor eyesight.

I'm sorry. I have no experience in this area.

Correction:

I meant the "Display size" (e.g. on my 3 Pixel devices).

then test this extension.

This extension will resize most of the compatabile components from single component/the whole screen/given arrangements/Whole screen except particular component

Leave the last function and test. Stil it have to be corrected

How and for what reason should one know in advance which settings the user has made in the device settings, especially regarding the display size?

me too had the same thought so i was worked and comes to an conclusion that i am leaving the choice from the user also if i open the apk in small size screen what will happen? so i tried this final code and works like responsive in different devices with variable width. You can test with auto rotation on and off to realise the working of code.
