I suppose abstract records are not allowed, so checking for the absence of a body is fine, however, wouldn't it be better to use getter.fromSource() instead

Records are implicitly final and therefore can't be abstract. It looks like checking fromSource() would work as well, but I didn't expect it based on the qldoc of fromSource() - it states:
* Holds if this element pertains to a source file.
*
* Elements pertaining to source files may include generated elements
* not visible in source code, such as implicit default constructors.
So I would actually expect fromSource() to hold for a generated getter when the corresponding record is fromSource(). I wonder why that isn't the case.

Ok, sounds like it's best to keep using the empty body check.

Could you also add some test with fields that have explicit "get" methods? I think one field with a sensible get method that just returns the field (has flow) and one silly get method that returns a constant (no flow)

Looks good to me. Could you add some more tests and perhaps use fromSource()?

This adds support for flow through Java 14 records.
