How can I have a dialog with 95% of the width of the landscape screen in compose? setting modifier.fillmaxwidth(0.95f) doesnt work. It seems that Dialog class has a forced maximum width. I tryed disabling it, using usePlatformDefaultWidth = false but then it ignores the width of their childrens and it has more width than the screen itself.

you can't (i hope someone here can prove me wrong).

this is why http://composeunstyled.com/dialog exists so you can size and style your dialogs exactly as you want

[Pablo]

you mean is not possible to do it with the default dialog classes given by compose? and that we are forced to import third party libraries to do it?

[Pablo]

I hope that is not correct

yes. dialogs on android (which i am assuming you are on) have a fixed max width, last time i used it which was a while.

you are not forced to use a 3rd party library and you can override this but it is a bit involved. requires to create a fully transparent dialog which takes the full screen size via xml themes

in Android, how to get available height? without the unusable parts (top camera part and botom buttons if they are present)

[Mike]

If you need a value you could get systemBars insets from WindowInsets and subtract from screen height. More here:
https://developer.android.com/develop/ui/compose/layouts/insets

[Pablo]

so there is not an automatically generated value that returns the total available height substracting automatically bars, top header etc... if present?

[Pablo]

that is a must

[Alex Styl]

never really had a need for that. what are u trying to achieve?

I disscovered a way to use the normal dialog with a custom width and height, but I need to know the exact available space substrating the size occupied by the OS components
