OverflowBounds class
Represents the bounds of content that overflows beyond the viewport edges.
OverflowBounds describes how much content extends beyond each edge of the viewport in a layout container. This is used to determine scrolling needs and handle overflow behavior.
Positive values indicate content extending beyond the viewport:
- top: Content above the viewport top edge
- bottom: Content below the viewport bottom edge
- left: Content to the left of the viewport left edge
- right: Content to the right of the viewport right edge
A value of 0 indicates no overflow in that direction.
Constructors
- OverflowBounds({required double top, required double bottom, required double left, required double right})
-
Creates an OverflowBounds with the specified overflow amounts.
