In this guide, we will discuss For-in Loop in Dart Programming Language. The for…in loop is used to loop through an object’s properties.

Following is the syntax of ‘for…in’ loop.

for (variablename in object){  
   statement or block to execute  
}

In each iteration, one property from the object is assigned to the variable name and this loop continues till all the properties of the object are exhausted.

Example

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

It should produce the following output −

12 
13 
14
