Are there any official docs that state compose will make touch targets 48.dp by default? I remember it coming up a few times in this slack but can't seem to find it.

Not Compose itself, but specifically the Material library that ships as part of Compose distribution

In https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]commonMain/kotlin/androidx/compose/material3/Surface.kt;l=221

interesting! let me investigate further. but does this mean that anything on a m3 Surface will have min touch target size applied, or does it mean that all material components have the minimumInteractiveComponentSize modifier set to them?

[Kirill Grouchnikov]

Everything that uses that modifier directly or indirectly. Components such as buttons and chips use the Surface composable under the hood, so that's how they get that indirectly.

[Kirill Grouchnikov]

But only the Surface variant that gets the onClick lambda. So if you have M3's Surface and then inside just a Box with a clickable modifier, that won't apply the minimum touch size

thank you for teaching!
