* [flutter_tools] [dap] Ensure DAP sends app.stop/app.detach during terminate
Fixes an issue where the flutter_tester device may not be cleaned up correctly if we just terminate the Flutter process.
* Update integration test expectations
* Revert accidental commit
Since 02d9c3e6a5 this flag does absolutely nothing. The behaviour it controlled is now automatic and the flag is not required.
The flag will be removed from the Dart SDK in the future after Flutter is no longer using it.
* [flutter_tools] [dap] Add support for passing env variables to spawned processes
* Use named args
* Use in-memory fs and FakePlatform
* Pass filesystem style to MemoryFileSystem
* Fix issues running integration tests through DAP
These adapters were incorrectly trying to connect a DDS instance even when Flutter would create its own. This change disables DDS in the DAP layer and leaves it to Flutter (although it passes `--no-dds` on to Flutter if provided to the DAP process).
Also fixes an issue where we would unnecessarily connect the VM Service for tests even in 'noDebug' mode because of a change/fix that now includes a 'vmServiceUri' in the `test.startedProcess` event.
* Don't terminate Dart process pids from VM Service
These processes may be on another device, and in the case of attach the debugee should not be terminated anyway.
* Add support for attachRequest in DAP, which runs "flutter attach"
* Update DAP docs for attachRequest
* Improve doc comments
* Fix comments
* Remove noDebug from attach + create a getter for `debug`
* Fix indent
