merhaba arkadaşlar şu kodları inceleyip nereye null check yapmam gerektiini söyler misiniz acaba?
class _Employee {
String? empName;
int? empAge;
int? empSalary;

String get employeeName {
return empName!;
}

void set employeeName(String name) {
this.empName = name;
}

void set employeeAge(int age) {
if (age == null) {
print(“please give a number”);
} else if (age <= 18) {
print(“please give a value number”);

  this.empAge = age;
}

}

int get employeeAge {
return empAge!;
}

void set employeeSalary(int salary) {
salary <= 0
? print(“Salary cannot be less than 0”)
: this.empSalary = salary;
}

int get employeeSalary {
return empSalary!;
}
}

void main() {
_Employee emp = _Employee();
emp.employeeName;
emp.employeeAge;
emp.employeeSalary;
print(“Employee’s Name is : ${emp.employeeName}”);
print(“Employee’s Age is : ${emp.employeeAge}”);
print(“Employee’s Salary is : ${emp.employeeSalary}”);
}
