unnecessary_null_in_if_null_operators
Avoid using null
in ??
operators.
Details
#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:
dart
var x = a ?? null;
var y = null ?? 1;
GOOD:
dart
var x = a ?? 1;
Enable
#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:
analysis_options.yaml
yaml
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:
analysis_options.yaml
yaml
linter:
rules:
unnecessary_null_in_if_null_operators: true
