unnecessary_null_checks
Unnecessary use of a null check ('!').
Description
#The analyzer produces this diagnostic when a null check operator (!
) is
used in a context where a nullable value is acceptable.
Example
#The following code produces this diagnostic because a null check is being
used even though null
is a valid value to return:
dart
int? f(int? i) {
return i!;
}
Common fixes
#Remove the null check operator:
dart
int? f(int? i) {
return i;
}
