Allow sheet to be dragged only when scrolling starts at the edge

[haroke4]

Hi,

First of all, thank you for this fantastic package!

I would like to replicate a specific behavior demonstrated in the attached video:

Draggable Behavior at Start: The bottom sheet starts as draggable.
Scrollable Upon Scrolling: When I begin scrolling within the sheet, it seamlessly transitions to a scrollable state.
Graceful Overscroll Handling: On overscrolling at the top of the sheet, it doesn't immediately become draggable again. Instead, it waits for the scrollable content to return to its initial position after the overscroll before transitioning back to draggable mode.
How can I achieve this behavior using flutter_smooth_sheets? Are there built-in configurations or examples that match this behavior?

Thanks for your help!

Hi @haroke4,

Unfortunately, the current version does not support that behavior. Overscrolling always affects the position of the sheet.
I'm planning to add a flag in a future version to support this behavior.
