Is there a way to combine `WindowInsets` with `PaddingValues

Question

Is there a way to combine `WindowInsets` with `PaddingValues` I need both for `contentPadding` in a `LazyColumn`

What do you mean by `combine` If you explain a bit better I think I might be able to help

WindowInsets + PaddingValues

Tgo1014 · Answer

I ve came up with this actually but wanted to know if there s something official ``` Composable operator fun PaddingValues plus paddingValues PaddingValues PaddingValues val layoutDirection = LocalLayoutDirection current return PaddingValues top = this calculateTopPadding + paddingValues calculateTopPadding bottom = this calculateBottomPadding + paddingValues calculateBottomPadding start = this calculateStartPadding layoutDirection + paddingValues calculateStartPadding layoutDirection end = this calculateEndPadding layoutDirection + paddingValues calculateEndPadding layoutDirection ```

And use it like this ```WindowInsets navigationBars asPaddingValues + PaddingValues 16 dp ```

Okay now I understood your question smile I don t think I ve seen any other official API for this either This looks just fine I d do the same

ephemient · Answer

why not ```operator fun PaddingValues plus that PaddingValues PaddingValues = object PaddingValues override fun calculateBottomPadding Dp = this plus calculateBottomPadding + that calculateBottomPadding override fun calculateLeftPadding layoutDirection LayoutDirection Dp = this plus calculateLeftPadding layoutDirection + that calculateLeftPadding layoutDirection override fun calculateRightPadding layoutDirection LayoutDirection Dp = this plus calculateRightPadding layoutDirection + that calculateRightPadding layoutDirection override fun calculateTopPadding Dp = this plus calculateTopPadding + that calculateTopPadding ``` which avoids the need to make it ` Composable`

< ephemient> that s really cool thanks for the code smile

Alex Vanyo · Answer

Not only does that avoid the need to make it ` Composable` it also delays the phase from composition to layout which can be good for performance for animations and some inset quirks

I don t think I would know even half of what I know now regarding Kotlin compose and android in general if I never joined this slack channel It s been a vital point in my progression it s honestly one of the best things I did back in the day sweat smile

one thing I did a lot of as an early user of Stack Overflow and which I think applies here too if you see a question you don t know the answer to try to do some research yourself you don t have to share if you didn t find an answer or don t have confidence in it but doing that first and then comparing to other answers is a great way to learn at least in my experience
