Using short function syntax to get rid of linter hints

[zoechi]

info: Use => for short members whose body is a single return statement. (prefer_expression_function_bodies at [datingnode] lib/src/queries_enums.g.dart:4650)

Alternatively some way to get // ignore_for_file: ... comments added to generated code to suppress such lints and errors would help as well.

As always super fast response. I love to use built_value.
