Get Common substring between list and string Flutter

Sample 1:

tags = ['what','play','school']
string = "what is your name?"

Output = ['what']

Sample 2:

tags = ['what is','play football','school','food']
string = "what is your school name? Do you play football there?"

Output = ['what is','school',"play football"]

How can I achieve this in flutter?

You can use where to find all words present in the string.

void main() {
  List<String> tags = ['what', 'play', 'school'];
  String _string = "what is your name?";

  List<String> commonWords = [...tags.where(_string.contains)];
  print(commonWords); // [what]
}
