Updated tests in dev, examples/api, and tests/widgets to ensure that they continue to pass when the default for `ThemeData.useMaterial3` is changed to true. This is the final set of changes required for https://github.com/flutter/flutter/issues/127064.
The files in this directory are used as part of the tests in the
flutter_tools
package. Some are here because here these tests need a
pubspec.yaml
that references the flutter framework (which is
intentionally not true of the flutter_tools
package). Others are
here mostly out of peer pressure.
