This avoids json encoding that was otherwise happening even in product mode. JSON encoding shows up CPU profiling as taking significant time, particularly on low end devices.

Calling `postEvent()` or `registerExtension()` from the
dart:developer library now sends messages via global functions
that can be set by the development infrastructure. For example,
these hooks are set by package:dwds.
When there is no debugger attached to the app, calling `postEvent()`
or `registerExtension()` will produce a warning once each to avoid
spamming the debug log with messages that do nothing.
For backwards compatibility, when a debugger is attached but the
hooks have not defined continue to write the events to the
console.debug log. This support will be removed when package:dwds
no longer reads from the log.
