How to convert list<String> into String in Dart without iteration?
StringListDartString Problem Overview
Is there a method in Dart like the String.join() method in Java & c#?
input:
nums: ["20", "3005", "2"]
output:
nums = "2030052"
String Solutions
Solution 1 - String
join is a method of the List class, rather than String:
List<String> yourList = ["20", "3005", "2"];
// To test that the above the above
yourList.join() == '2030052'; // true
yourList.join(',') == '20,3005,2'; // true, with "," delimiter
Solution 2 - String
This might not be the best solution, but you can reduce a collection to a single value by iteratively combining elements of the collection using the reduce method in Dart Lists.
String nums = numsList.reduce((value, element) => value + ',' + element);
You have to remember that, the iterable must have at least one element. If it has only one element, that element is returned.
Solution 3 - String
List<String> onlyString=[];
onlyString.add("Flutter");
for(int i=0; i < onlyString.length; i++){
print(onlyString[i].toString());}
