downgrade analysis failed failed with 3 errors:

• NON_ABSTRACT_CLASS_INHERITS_ABSTRACT_MEMBER - lib/utils/value_layout_builder.dart:65:7 - Missing concrete implementations of 'mixin RenderObjectWithLayoutCallbackMixin on RenderObject.runLayoutCallback' and 'mixin RenderObjectWithLayoutCallbackMixin on RenderObject.scheduleLayoutCallback'.
• MIXIN_APPLICATION_NOT_IMPLEMENTED_INTERFACE - lib/utils/value_layout_builder.dart:68:9 - 'RenderConstrainedLayoutBuilder<BoxValueConstraints
• UNDEFINED_METHOD - lib/utils/value_layout_builder.dart:106:5 - The method 'rebuildIfNecessary' isn't defined for the type 'RenderValueLayoutBuilder'.

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.
