# frozen_string_literal: true

# This cop ensures that if a class uses `graphql_name`, then
# it's the first line of the class
#
# @example
#
#   # bad
#   class AwfulClass
#     field :some_field, GraphQL::Types::JSON
#     graphql_name 'AwfulClass'
#   end
#
#   # good
#   class GreatClass
#     graphql_name 'AwfulClass'
#     field :some_field, GraphQL::Types::String
#   end
