# scrollIndicatorsFlash(trigger:)

Flashes the scroll indicators of scrollable views when a value changes.

## Declaration

```swift
nonisolated func scrollIndicatorsFlash(trigger value: some Equatable) -> some View

```

## Parameters

- `value`: The value that causes scroll indicators to flash. The value must conform to the doc://com.apple.documentation/documentation/Swift/Equatable protocol.

## Return Value

Return Value A view that flashes any visible scroll indicators when a value changes.

## Discussion

Discussion When the value that you provide to this modifier changes, the scroll indicators of any scrollable views within the modified view hierarchy briefly flash. The following example configures the scroll indicators to flash any time flashCount changes: @State private var isPresented = false @State private var flashCount = 0

ScrollView {     // ... } .scrollIndicatorsFlash(trigger: flashCount) .sheet(isPresented: $isPresented) {     // ... } .onChange(of: isPresented) { newValue in     if newValue {         flashCount += 1     } } Only scroll indicators that you configure to be visible flash. To flash scroll indicators when a scroll view initially appears, use scrollIndicatorsFlash(onAppear:) instead.
