• You can use >, >=, <, <= operators, to compare String lengths. Also - to subtract a text from a String

String s1 = 'esentis';
String s2 = 'dev';
print(s1 > s2); // prints true
print(s1 >= s2); // prints true
print(s1 < s2); // prints false
print(s1 <= s2); // prints false
print(s1-'tis'); // prints 'esen'
