Properties
| Property | Type | Description |
|---|---|---|
| scrollDirection | StacAxis | The axis along which the grid scrolls. Defaults to Axis.vertical. |
| reverse | bool | Whether the grid scrolls in the reverse direction. Defaults to false. |
| primary | bool | Whether this is the primary scroll view. Defaults to false. |
| physics | StacScrollPhysics | The physics for the scroll view. |
| shrinkWrap | bool | Whether the extent of the scroll view in the scrollDirection should be determined by the contents being viewed. Defaults to false. |
| padding | StacEdgeInsets | The amount of space by which to inset the grid. |
| crossAxisCount | int | The number of children in the cross axis. |
| mainAxisSpacing | double | The amount of space between the children in the main axis. Defaults to 0.0. |
| crossAxisSpacing | double | The amount of space between the children in the cross axis. Defaults to 0.0. |
| childAspectRatio | double | The ratio of the cross-axis to the main-axis extent of each child. Defaults to 1.0. |
| mainAxisExtent | double | The extent of each child in the main axis. |
| addAutomaticKeepAlives | bool | Whether to add automatic keep-alives. Defaults to true. |
| addRepaintBoundaries | bool | Whether to add repaint boundaries. Defaults to true. |
| addSemanticIndexes | bool | Whether to add semantic indexes. Defaults to true. |
| cacheExtent | double | The extent to which the content is cached. |
| children | List<StacWidget> | The widgets below this widget in the tree. Defaults to an empty list. |
| semanticChildCount | int | The number of children for semantics purposes. |
| dragStartBehavior | StacDragStartBehavior | The drag start behavior. Defaults to DragStartBehavior.start. |
| keyboardDismissBehavior | StacScrollViewKeyboardDismissBehavior | The keyboard dismiss behavior. Defaults to ScrollViewKeyboardDismissBehavior.manual. |
| restorationId | String | The restoration ID to save and restore the scroll offset. |
| clipBehavior | StacClip | The clip behavior of the grid. Defaults to Clip.hardEdge. |
