getOffset abstract method Null safety

Offset getOffset(
  1. ScaffoldPrelayoutGeometry scaffoldGeometry
)

Places the FloatingActionButton based on the Scaffold's layout.

This uses a ScaffoldPrelayoutGeometry, which the Scaffold constructs during its layout phase after it has laid out every widget it can lay out except the FloatingActionButton. The Scaffold uses the Offset returned from this method to position the FloatingActionButton and complete its layout.

Implementation

Offset getOffset(ScaffoldPrelayoutGeometry scaffoldGeometry);
