A little over two years ago, we started enforcing a deprecation policy
in order to keep the framework clean and clear for everyone.
This policy brought with it the introduction of Flutter fix
to help migrate deprecated code, along side our long practice of providing migration guides
when making breaking changes.
Over the past few years we've only applied this policy within the flutter package. This allowed us to iterate on the process and gather feedback from users to provide as smooth a transition as possible. Given the feedback we have received, we would like to expand the policy now to include the flutter_test package.
