[dart-misc] Resolving annotation node from an annotated field using a code_transformer

[Adam Bender]

I was doing some fiddling with a code_transformer the other day and I ran
into a problem I couldnt figure out how to solve. Given a class like this:

class MyClass {
@somethingSpecial
Foo foo;

@somethingSpecial
Foo get aDifferentFoo => new Foo();
}

static const somethingSpecial = const _SomethingSpecial();
class _SomethingSpecial{
const _SomethingSpecial();
}

When running the transformer across this class I see that I am able to
resolve the actual Annotation node from the getter but I can only access
the AnnotationElement for the field. I have tried looking around the
FieldElement API including the implied getter and setter but I dont see
anyway to resolve the actual Annotation AST node starting from a field and
that just seems weird. No matter where I looked I ended up with the null
node or not a node lacking metadata. Im sure I am missing something obvious
but I cant quite crack it. Any AST experts have any pointers for how I sort
this out?
