Convert Variable From Int To String In Dart

In this article, we’ll be discussing how to convert an integer variable into a string in Dart programming language. This technique can be useful when you need to handle numbers but in a string format. There are different ways to achieve this, but we will focus solely on the inbuilt Dart method, ‘toString()’ for this tutorial.

Code Snippet: Using toString() Method

void main() {
  int number = 12345;
  String numberString = number.toString();

  print(numberString);
}

Code Explanation: Using toString() Method

In the above-mentioned Dart code, we are trying to convert an integer to a string value. Let’s break it down, step by step.

1. void main(): This line defines our main function. As per its functionality in most programming languages, it is the entry point for our Dart script.

2. int number = 12345;: Here, we are declaring an integer variable, ‘number’, and have assigned the value 12345 to it.

3. String numberString = number.toString();: In this step, the ‘toString()’ method transforms the integer value assigned to ‘number’ into its equivalent string form. Then we store this newly converted string into another variable ‘numberString’. In Dart, the ‘toString()’ method can be used with many different types of data, including integers.

4. print(numberString);: The ‘print’ function is used here to output ‘numberString’ to the console. Since the integer has been transformed into a string, the console will display the integer value as a string.

Through this simple technique, you can convert any integer variable into a string in Dart and can manipulate or use it as per your coding requirements. Understanding such conversions helps in managing and transforming data more effectively in Dart.
