Originally landed in https://github.com/flutter/flutter/pull/139549 Originally reverted in https://github.com/flutter/flutter/pull/140085 - Remove all use of global variables. - Always pass in all dependencies, only create them in main or in tests. - Pass in the "print" primitive. - Make all network traffic retry (except when run locally, when it just auto-passes). - Enable tests to be run in random order. - Better error messages
