Use ?? operators to convert nulls to bools.

Enable

#

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

analysis_options.yaml
yaml 
linter:  rules:  - use_if_null_to_convert_nulls_to_bools

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

analysis_options.yaml
yaml 
linter:  rules:  use_if_null_to_convert_nulls_to_bools: true
