Fixes https://github.com/dart-lang/sdk/issues/61597 * Remove the old caching mechanism for the old way of sourcing files. * Remove BlazeMockPackages._addFiles, and rename _addFiles2 to _addFiles. A few trailing fixing included: * Flex.new has a required direction parameter. * TextOverflow comes from 'package:flutter/src/painting/text_painter.dart'. * A few stray imports needed to resolve types. * DiagnosticableTree.debugDescribeChildren is marked external so that subclasses need not implement it themselves. * In sort_child_properties_last, RawMaterialButton is in the material library.
