How to disable strict_raw_type and inference_failure_on_function_return_type from analysis_option.yaml on Flutter?

[ousvat]

Describe the bug
I have a lot of warnings with strict_raw_type and inference_failure_on_function_return_type from the dart analyzer.

I tried to pass to the analysis_option.yaml the rules:

linter:
  rules:
    strict_raw_type: false
    inference_failure_on_function_return_type: false

But it says that are not recognized as lint rules.

How can I disable these rules?
