Parse String to int or double in Dart Flutter

How to parse a String into an Int in Dart.

String myString = "1";
int.parse(myString);

Remember to use try and catch since it can throw FormatException.

Or you can try to parse it!

int.tryParse(myString);

So no need to wrap it in a try catch, since it will return null in case it fails to parse that String into an integer.

 

You can use the same with double.
