Alternative for deprecated MethodElement.computeNode() method in analyzer

[jorgecoca]

Thank you for taking the time to file an issue!

In order to route, prioritize, and act on this, please include:

• Dart SDK Version (2.2.0)
• macOS

In this commit, some of the contents of pkg/analyzer/lib/dart/element/element.dart were annotated as @deprecated; however, the documentation does not seem to suggest any alternatives.

I used to use computeNode(), from the class MethodElement, to retrieve the body implementation of a MethodElement as follows:

final commonBody = methodElement.computeNode().body;

but not the analyzer is marking it as deprecated, so I would like to understand what is the alternative for this use case.

PS. To give some more context, this is part of a code generator (using source_gen) that is parsing the contents of files annotated with certain metadata.

Thanks!

I am also using .computeNode().body to get source code of MethodElement.
computeNode was now removed with 5d4cd6d

Is there any proper way to get method source code now?

I found an answer in this SO question: https://stackoverflow.com/questions/57030992/how-do-i-get-the-astnode-from-some-element-in-dart-analyzer-source-gen

Seems that instead of computeNode you can get AstNode from Element like so:

AstNode node = element.session.getParsedLibraryByElement(element.library).getElementDeclaration(element).node;
And this object can be used to get source code.
