downgrade analysis failed failed with 5 errors:

• INVALID_IMPLEMENTATION_OVERRIDE - lib/src/rendering/sliver_layout_grid.dart:139:7 - 'RenderSliverVariableSizeBoxAdaptor.adoptChild' ('void Function(RenderBox)') isn't a valid concrete implementation of 'RenderObject.adoptChild' ('void Function(RenderObject)').
• INVALID_OVERRIDE - lib/src/rendering/sliver_variable_size_box_adaptor.dart:195:8 - 'RenderSliverVariableSizeBoxAdaptor.adoptChild' ('void Function(RenderBox)') isn't a valid override of 'RenderObject.adoptChild' ('void Function(RenderObject)').
• INVALID_ASSIGNMENT - lib/src/widgets/cell.dart:146:42 - A value of type 'RenderObject?' can't be assigned to a variable of type 'AbstractNode?'.

Run flutter pub downgrade and then flutter analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
