Properties
- alignment → Alignment
-
Alignment of the sheet. Default Alignment.bottomCenter
final

final
- duration → Duration
-
Duration for sheet expansion animation. Default Duration(milliseconds: 0)
final
- expandedWidget → Widget
-
Widget to show on expended sheet
final
- expansionExtent → double
-
Increment expansionExtent on minExtent to change from previewWidget to expandedWidget
final
- hashCode → int
-
The hash code for this object.
no setterinherited

pass current extent (position) as an argument
final
- previewWidget → Widget
-
Widget to show on collapsed sheet
final
- runtimeType → Type
