Code Review
This pull request updates FutureDataHandler to lazily initialize completers and handle null messages, refactors page transitions in main.dart to use PageRouteBuilder with zero transition durations, and adds a wait for transient callbacks in the integration test. Feedback suggests adding a timeout to the lazy completer future in handleMessage to prevent tests from hanging indefinitely on invalid messages.
