How to find the AstNode related to where an identifier is defined?

[dark...@gmail.com]

Is there an easy way to locate the AstNode associated to where a variable was defined?
For example consider:

Consumer(

builder: (context, ref) {

return Consumer(

builder: (context, ref) {},

);

},

);

Given a `MethodInvocation` on a "ref" object, I want to know which ref specifically was targeted, and I specifically need an AstNode (not an Element).

I want an AstNode, because I then want to visit the ancestors of that AstNode. In particular, I wish to look for enclosing InstanceCreationExpressions. And that information wouldn't be available with Elements.

Forgot to say hello. So Hello!

And thanks :)

I don't know of one.

Not that I'm aware of. If the reference is always to a local variable then you'll need to walk up the AST from the method invocation looking for the declaration of that variable.
