Using int.parse() method
To convert a string to an integer, we can use the built-in int.parse() method in Dart.
The int.parse() function takes the string as an argument and converts it to the integer.
Here is an example, that converts the string “21” to an integer:
void main() { var a = "21"; var num = int.parse(a); // converts string to int print(num);}Output:
21
Similarly, we can also convert the string to double by using the double.parse() method in Dart.
void main() { var a = "100.343"; var result = double.parse(a); // converts string to double print(result);}Output:
100.343
