Dart Programming Examples

Dart Programming - Label with Break Example

dart

void main() { 
   outerloop: // This is the label name 
   for (var i = 0; i < 5; i++) { 
      print("Innerloop: ${i}"); 
      innerloop: 
      for (var j = 0; j < 5; j++) { 
         if (j > 3 ) break ; 
         // Quit the innermost loop 
         if (i == 2) break innerloop; 
         // Do the same thing 
         if (i == 4) break outerloop; 
         // Quit the outer loop 
         print("Innerloop: ${j}"); 
      } 
   } 
}

Dart Programming - Continue Statement

dart

void main() { 
   var num = 0; 
   var count = 0; 
   for(num = 0;num<=20;num++) { 
      if (num % 2==0) { 
         continue; 
      } 
      count++; 
   } 
   print(" The count of odd values between 0 and 20 is: ${count}"); 
}

Dart Programming - Break Statement

dart

void main() { 
   var i = 1; 
   while(i<=10) { 
      if (i % 5 == 0) { 
         print("The first multiple of 5  between 1 and 10 is : ${i}"); 
         break ;    
         //exit the loop if the first multiple is found 
      } 
      i++; 
   }
}

Dart Programming - do while Loop

dart

void main() { 
   var n = 10; 
   do { 
      print(n); 
      n--; 
   }
   while(n>=0); 
}

Dart Programming - while Loop

dart

void main() { 
   var num = 5; 
   var factorial = 1; 
   while(num >=1) { 
      factorial = factorial * num; 
      num--; 
   } 
   print("The factorial  is ${factorial}"); 
}

Dart Programming - for-in Loop

dart

void main() { 
   var obj = [12,13,14]; 
   for (var prop in obj) { 
      print(prop); 
   } 
}

Dart Programming - for Loop Example2

dart

void main() { 
   for(var temp, i = 0, j = 1; j<30; temp = i, i = j, j = i + temp) { 
      print('${j}'); 
   } 
}

Dart Programming - For Loop Example1

dart

void main() { 
   var num = 5; 
   var factorial = 1; 
   for( var i = num ; i >= 1; i-- ) { 
      factorial *= i ; 
   } 
   print(factorial); 
}

Dart Programming - Logical Operators Example

dart

void main() { 
   var a = 10; 
   var b = 12; 
   var res = (a>b)||(b<10); 
   print(res);  
   var res1 =!(a==b); 
   print(res1); 
}

Dart Programming - Assignment Operators

dart

void main() { 
   var a = 12; 
   var b = 3; 
     
   a+=b; 
   print("a+=b : ${a}"); 
     
   a = 12; b = 13; 
   a-=b; 
   print("a-=b : ${a}"); 
     
   a = 12; b = 13; 
   a*=b; 
   print("a*=b' : ${a}"); 
     
   a = 12; b = 13; 
   a/=b;
   print("a/=b : ${a}"); 
     
   a = 12; b = 13; 
   a%=b; 
   print("a%=b : ${a}"); 
}
