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

analysis_options.yaml
yaml 
linter:
  rules:
    - initialize_in_field_declaration

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

analysis_options.yaml
yaml 
linter:
  rules:
    initialize_in_field_declaration: true
