Dart & Flutter: 2 Ways to Count Words in a String
This short post shows you 2 ways to count the number of words in a given string.
1. Using split() method
We can use the split() method to return the list of the substrings between the white spaces in the given string.
final String s = 'Kindacode.com is a website about programming.'; final List l = s.split(' '); print(l.length);
2. Using Regular Expression
Using regular expression is a little bit more complicated but it gives you more flexibility.
final String s = 'Kindacode.com is a website about programming. Under_score en-dash em-dash and some special words.'; final RegExp regExp = new RegExp(r"[\w-._]+"); final Iterable matches = regExp.allMatches(s); final int _count = matches.length; print(_count);
