… the engine's UI thread The service protocol's ListViews method needs to return description data for each engine in the process. Previously ListViews would queue a task to each UI thread to gather this data. However, the UI thread might be blocked from executing tasks (e.g. if the Dart isolate is paused), resulting in a deadlock. This change provides a copy of the engine's description data to the ServiceProtocol's global list of engines, allowing ListViews to run without accessing any UI threads. Fixes flutter/flutter#24400

The service protocol's ListViews method needs to return description data for
each engine in the process. Previously ListViews would queue a task to each
UI thread to gather this data. However, the UI thread might be blocked from
executing tasks (e.g. if the Dart isolate is paused), resulting in a deadlock.
This change provides a copy of the engine's description data to the
