verticalScroll
Compose Modifier
Common
fun Modifier.verticalScroll(
state: ScrollState,
enabled: Boolean = true,
flingBehavior: FlingBehavior? = null,
reverseScrolling: Boolean = false,
) =
scroll(
state = state,
isScrollable = enabled,
reverseScrolling = reverseScrolling,
flingBehavior = flingBehavior,
isVertical = true,
useLocalOverscrollFactory = true,
)
Modify element to allow to scroll vertically when height of the content is bigger than max constraints allow.
In order to use this modifier, you need to create and own ScrollState
See the other overload in order to provide a custom OverscrollEffect
Parameters
state | state of the scroll |
enabled | whether or not scrolling via touch input is enabled |
flingBehavior | logic describing fling behavior when drag has finished with velocity. If null , default from ScrollableDefaults.flingBehavior will be used. |
reverseScrolling | reverse the direction of scrolling, when true , 0 ScrollState.value will mean bottom, when false , 0 ScrollState.value will mean top |

Parameters
state | state of the scroll |
overscrollEffect | the OverscrollEffect that will be used to render overscroll for this modifier. Note that the OverscrollEffect.node will be applied internally as well - you do not need to use Modifier.overscroll separately. |

flingBehavior | logic describing fling behavior when drag has finished with velocity. If null , default from ScrollableDefaults.flingBehavior will be used. |
reverseScrolling | reverse the direction of scrolling, when true , 0 ScrollState.value will mean bottom, when false , 0 ScrollState.value will mean top |
