Reverse A String In Dart

Reverse a string is one of the fundamental programming practices commonly used in various applications. This article sheds light on how to achieve this task in Dart programming language through step-by-step explanations.

Code Snippet: Reverse a String in Dart

Here’s a simple code snippet that showcases how to reverse a string in Dart:

void main() {
  String str = "Hello, Dart";
  String reversedStr = str.split('').reversed.join('');
  print(reversedStr);
}

In this code snippet, the string “Hello, Dart” will be reversed and printed as “traD ,olleH”.

Code Explanation: Reverse a String in Dart

1. First, we are defining the main function that serves as our starting point. Inside the main function, we define our string that we’d like to reverse:

void main() {
  String str = "Hello, Dart";
}

2. Next, to reverse the order of the characters within our string, we take advantage of the split('') method, which disintegrates the str into an array of characters:

  String str = "Hello, Dart";
  str.split('');

3. Subsequently, the reversed property is applied to the created list, resulting in a new iterable object that iterates through the characters in reverse:

  str.split('').reversed;

4. Finally, the join('') method is executed to stitch the reversed iterable back into a string:

  String reversedStr = str.split('').reversed.join('');

5. To check the result, we print reversedStr:

  print(reversedStr);

When we run the main function, the string “Hello, Dart” is reversed as “traD ,olleH”.

And, that is it! You have successfully executed string reversal in Dart. This technique can be incorporated in a vast array of projects, among them being palindrome checking programs or simply creating a reversed user input feature.
