unnecessary_null_in_if_null_operators

Avoid using null in ?? operators.

AVOID using null as an operand in ?? operators.

Using null in an if null operator is redundant, regardless of which side null is used on.

BAD:

var x = a ?? null; var y = null ?? 1; 

GOOD:

var x = a ?? 1; 

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

linter:  rules:  - unnecessary_null_in_if_null_operators 

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

linter:  rules:  unnecessary_null_in_if_null_operators: true
