In this guide, we will discuss Collection List in Dart Programming Language. A List is simply an ordered group of objects. The dart:core library provides the List class that enables creation and manipulation of lists.

Lists in Dart can be classified as −

• Fixed Length List − The list’s length cannot change at run-time.
• Growable List − The list’s length can change at run-time.

Example

Given below is an example of Dart implementation of List.

void main() { 
   List logTypes = new List(); 
   logTypes.add("WARNING"); 
   logTypes.add("ERROR"); 
   logTypes.add("INFO");  
   
   // iterating across list 
   for(String type in logTypes){ 
      print(type); 
   } 
   
   // printing size of the list 
   print(logTypes.length); 
   logTypes.remove("WARNING"); 
   
   print("size after removing."); 
   print(logTypes.length); 
}

The output of the above code is as given below −

WARNING 
ERROR 
INFO 
3 
size after removing.
