This PR adds the following lint rules to our list: ``` always_put_required_named_parameters_first avoid_multiple_declarations_per_line avoid_positional_boolean_parameters avoid_returning_null_for_void avoid_returning_this avoid_unnecessary_containers enable_null_safety library_private_types_in_public_api no_leading_underscores_for_library_prefixes no_leading_underscores_for_local_identifiers prefer_null_aware_method_calls tighten_type_of_initializing_formals unnecessary_late use_setters_to_change_properties ``` And these rules were considered, and some changes were made according to them as a clean-up, but in many places they didn't make sense (`prefer_asserts_with_message` I would have included, but there were too many places that needed to be changes): ``` collection_methods_unrelated_type prefer_asserts_with_message avoid_renaming_method_parameters ```
