auto label is removed for flutter/flutter, pr: 123352, due to - The status or check suite Linux customer_testing has failed. Please fix the issues identified (or deflake) before re-applying this label. |

customer_testing failures are (unrelated) flakes hopefully fixed with flutter/tests#239. |

Part of #121573.
This change allows the root of the element tree to be any
Element(not just aRenderObjectElement). For that, it introduces theRootElementMixin, which can be used to make any Element subclass the root of the element tree. It replaces theRootRenderObjectElement, which is now deprecated in favor of the new mixin. In addition to that, it renames therenderViewElementaccessor on the WidgetsBinding torootElementto remove the implied assumption that the root is aRenderObjectElement.This is in preparation for further changes towards multi-view rendering, where the root of the element tree will not be backed by render objects, see https://docs.flutter.dev/go/multiple-views for the details of that.
