To enable the prefer_expression_function_bodies rule, add prefer_expression_function_bodies under linter > rules in your analysis_options.yaml file:

linter:  rules:  - prefer_expression_function_bodies 

If you're instead using the YAML map syntax to configure linter rules, add prefer_expression_function_bodies: true under linter > rules:

linter:  rules:  prefer_expression_function_bodies: true
