when starting dds: `Bad state: Failed to start Dart Development Service`

[andrewkolos]

On the 3.27 beta of Flutter, we are seeing this crash affecting many clients: flutter/flutter#158537. That thread documents the error messages we see coming from the tool. For quick reference, the one we see the most is

StateError: Bad state: Failed to start Dart Development Service
at DartDevelopmentService.startDartDevelopmentService(dds.dart:114)
at <asynchronous gap>(async)
at FlutterDevice.connect.<anonymous closure>(resident_runner.dart:295)
at <asynchronous gap>(async)

Expected behavior: the error message explains why dds failed to start

Here is the call site where the flutter tool enters package:dds: https://github.com/flutter/flutter/blob/04d3d1a4c3f005beb8cf37fb4f66ad6b7b8d666f/packages/flutter_tools/lib/src/resident_runner.dart#L291-L313.

Summary: The Dart Development Service (DDS) fails to start on Flutter 3.27 beta, resulting in a "Bad state: Failed to start Dart Development Service" error. The issue affects many users and lacks a clear explanation for the failure.

I believe this has been resolved. Will reopen if we come across this again.
