avoid_null_checks_in_equality_operators
Don't check for null
in custom ==
operators.
This rule has been removed as of the latest Dart releases.
Details
#DON'T check for null
in custom ==
operators.
As null
is a special value, no instance of any class (other than Null
) can be equivalent to it. Thus, it is redundant to check whether the other instance is null
.
BAD:
class Person {
final String? name;
@override
operator ==(Object? other) =>
other != null && other is Person && name == other.name;
}
GOOD:
class Person {
final String? name;
@override
operator ==(Object? other) => other is Person && name == other.name;
}
This rule has been removed.
