How to Convert String to Integer in Dart - Step by Step Examples

How to Convert String to Integer in Dart ?

To convert a String to an Integer in Dart, you can use the int.parse() function.

In this example,

We create a variable named str with a string value of "789".
We then use the int.parse() function to convert it to an integer and store the result in the variable number.
The int.parse() function parses the string and returns the equivalent integer value.
Finally, we print the value of number using print().

void main() {
  String str = "789";
  int number = int.parse(str);
  print("Integer value: $number");
}

Integer value: 789

In this example,

We create a variable named str with a string value of "012".
We then use the int.parse() function to convert it to an integer and store the result in the variable number.
The int.parse() function parses the string and returns the equivalent integer value.
Finally, we print the value of number using print().

void main() {
  String str = "012";
  int number = int.parse(str);
  print("Integer value: $number");
}

Integer value: 12
