0/20 points: Compatible with dependency constraint lower bounds

downgrade analysis failed failed with 13 errors:

• INVALID_OVERRIDE - lib/src/charts/base.dart:2949:16 - 'LoadingIndicator.createRenderObject' ('RenderObject Function(BuildContext)') isn't a valid override of 'AbstractLayoutBuilder.createRenderObject' ('RenderAbstractLayoutBuilderMixin<BoxConstraints, RenderObject> Function(BuildContext)').
• NON_ABSTRACT_CLASS_INHERITS_ABSTRACT_MEMBER - lib/src/charts/base.dart:2967:7 - Missing concrete implementations of 'mixin RenderObjectWithLayoutCallbackMixin on RenderObject.runLayoutCallback' and 'mixin RenderObjectWithLayoutCallbackMixin on RenderObject.scheduleLayoutCallback'.
• MIXIN_APPLICATION_NOT_IMPLEMENTED_INTERFACE - lib/src/charts/base.dart:2968:10 - 'RenderConstrainedLayoutBuilder<BoxConstraints, RenderBox>' can't be mixed onto 'RenderProxyBox' because 'RenderProxyBox' doesn't implement 'RenderObjectWithLayoutCallbackMixin'.

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.
