No node for typedefs

[jodinathan]

ParsedLibraryResult.getElementDeclaration(someTypeAliasElementImplVar) returns null only for typedef.

It seems for me that this is a bug.

How can I know the node for TypeAliasElementImpl elements?

is this a bug?

From my reading of the docs getElementDeclaration returns null for synthetic elements - you might check if someTypeAliasElementImplVar.isSynthetic is true, and if so see if nonSynthetic property gets you to an Element that works with this API.

no, typedefs are not synthetic, they are solid nodes.

I could find out the node for the typedef by looping through all nodes and check for node.element == myTypedefElement.

So the node and typedef element connection is there
