Add ignores to generated file

[MarcinusX]

Suggested by Diego on Slack:

I want to know if it's possible to add someone "ignores" in the generated file. I see in others generators that consider that cases. I use the package "lint" and it gave me some errors..
Always that regenerate the file I need to paste these ignores:

// ignore_for_file: unused_import
// ignore_for_file: directives_ordering
// ignore_for_file: type_annotate_public_apis
// ignore_for_file: prefer_const_constructors
// ignore_for_file: invalid_assignment
// ignore_for_file: argument_type_not_assignable
// ignore_for_file: prefer_const_constructors_in_immutables
// ignore_for_file: avoid_return_types_on_setters
// ignore_for_file: avoid_setters_without_getters
// ignore_for_file: sort_child_properties_last
// ignore_for_file: prefer_const_literals_to_create_immutables
// ignore_for_file: prefer_generic_function_type_aliases
// ignore_for_file: prefer_conditional_assignment
// ignore_for_file: avoid_unused_constructor_parameters
// ignore_for_file: prefer_typing_uninitialized_variables
// ignore_for_file: curly_braces_in_flow_control_structures
