   The unified_analytics bump landed with the pub roll in #195950, which moved flutter_tools to unified_analytics: 8.4.0. flutter_tools events now record leaf_tool = flutter-tool and root_tool resolved from DASH__TOOL (falling back to flutter-tool). The deprecated tool property stays flutter-tool.

   I'm keeping this open for one small follow-up. When flutter_tools starts a child process, it passes the parent's DASH__TOOL through unchanged, even if the value is invalid or names a shared component that can't be a root tool. flutter_tools itself ignores such a value, but its children would still receive it. I'll send a PR so that only a valid root tool is passed on, falling back to flutter-tool otherwise.
