如何调整Flutter中BottomSheet的elevation以显示在Sandwich下方？

Absolutely! Tweaking the elevation property is a totally valid and straightforward way to control the visual stacking order between your BottomSheet and Sandwich components—especially in Material Design-based frameworks like Jetpack Compose or Flutter.

Here’s the breakdown:

• The elevation property directly dictates a component’s position in the z-layer hierarchy. Components with a higher elevation value are rendered on top of those with lower values, since elevation ties into shadow depth and visual priority.
• To get your Sandwich component sitting above the BottomSheet, you just need to:
  • Assign a higher elevation value to the Sandwich component than the BottomSheet.
  • If either component uses a default elevation (most Material components do), make sure to explicitly override those values to lock in the desired order.

Quick Example (Jetpack Compose): #

// BottomSheet with lower elevation (renders below)
BottomSheet(
    elevation = 4.dp,
    // Other BottomSheet props
) {
    // BottomSheet content goes here
}

// Sandwich component with higher elevation (renders above)
SandwichComponent(
    elevation = 8.dp,
    // Other Sandwich props
)

A Quick Heads-Up: #

If adjusting elevation doesn’t seem to work right away, double-check if either component is wrapped in a parent container that uses clipping or has its own elevation/z-index settings—these can sometimes override child components’ elevation values. But in most standard layouts, elevation alone will fix your stacking issue.
