Enhances scroll bar functionality across various platforms, inspired by Google's Launcher3 FastScroller. Includes customizable styles and optional Material Design themes for seamless integration.
Implementing scroll bars in Compose Multiplatform
The scroll bar implementations available in androidx.compose.foundation:foundation library, but it is currently available for Compose Multiplatform without Android. (To be precise, it is available on all platforms except Android, but the implementation is not optimized for mobile.)
This library changes that, by providing the scroll bar implementations for many of the platforms supported by Compose Multiplatform. And more changes inspired by Google's Launcher3 FastScroller.
Usage is very simple:
import io.github.oikvpqya.compose.fastscroller.VerticalScrollbar
import io.github.oikvpqya.compose.fastscroller.material.defaultMaterialScrollbarStyle
import io.github.oikvpqya.compose.fastscroller.rememberScrollbarAdapter
@Composable
fun Screen() {
val state = rememberLazyListState()
LazyColumn(
modifier = Modifier.fillMaxSize(),
state = state,
) {
Box (/* ... */){
Image (/* ... */)
Text (fontSize = fontSize)
}
}
VerticalScrollbar(
modifier = Modifier.align(Alignment.TopEnd).fillMaxHeight(),
adapter = rememberScrollbarAdapter(scrollState = state),
style = defaultMaterialScrollbarStyle(),
enablePressToScroll = ,
)
}
See samples or github page.
In kmp sample app, you can see an example of a scrollbar indicator.
