Conversation
…applications (flutter#180905) DWDS can throw `DartDvelopmentServiceException` if DDS fails to connect to DWDS due to the target application shutting down immediately after launch. This change adds logic to catch this exception and exit gracefully. Fixes flutter#178151 --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>

Code Review
This pull request introduces improved error handling for web applications when the Dart Development Service (DDS) encounters a DartDevelopmentServiceException during startup. Specifically, it addresses cases where the application might shut down before DDS can fully establish its connection, preventing unhandled exceptions and ensuring a graceful exit. A new test case has been added to validate this specific error handling scenario.
