Dart string methods are built-in methods that you can use to manipulate and work with strings. Strings are a fundamental data type. A string is a sequence of characters.
Dart String can be created using single quotes or double quotes. i.e. characters enclosed within single (‘) or double (“) quotes. Strings are immutable in Dart language. It means that we cannot modify the string after it’s creation.
The String keyword is used to declare the string in Dart programs. The general syntax to declare the string is as follows:
String message = ‘Welcome to TestingDocs.com’;
String course_name = “Software Testing” ;
