How to extract number only from string in flutter?
Lets say that I have a string:
Now I need to parse 23 from both string. How do I extract that number or any number from a string value?
The following code can extract the number:
aStr = a.replaceAll(new RegExp(r'[^0-9]'),''); // '23'
You can parse it into integer using:
aInt = int.parse(aStr);
