   } 
   else if(num < 0) { 
      print("${num} is negative"); 
   } 
   else { 
      print("${num} is neither positive nor negative"); 
   } 
}

Dart Programming - Simple if else Example

      print("Outerloop:${i}"); 
      for (var j = 0; j < 5; j++) { 
         if (j == 3){ 
            continue outerloop; 
         } 
         print("Innerloop:${j}"); 
      } 
   }
