use_late_for_private_fields_and_variables
Use 'late' for private members with a non-nullable type.
Description
#The analyzer produces this diagnostic when a private field or variable is marked as being nullable, but every reference assumes that the variable is never null
.
Example
#The following code produces this diagnostic because the private top-level variable _i
is nullable, but every reference assumes that it will not be null
:
void f() {
_i!.abs();
}
int? _i;
Common fixes
#Mark the variable or field as being both non-nullable and late
to indicate that it will always be assigned a non-null:
void f() {
_i.abs();
}
late int _i;
