Strings in Dart

A Dart string is a sequence of UTF-16 code units. With the same rule as that of Python, you can use either single or double quotes to create a string. The string starts with the datatype Var : 

var string = "I love GeeksforGeeks";
var string1 = 'GeeksforGeeks is a great platform for upgrading skills';

Both the strings above when running on a Dart editor will work perfectly.

You can put the value of an expression inside a string by using ${expression}. It will help the strings to concatenate very easily. If the expression is an identifier, you can skip the {}. 

Dart

void main () {
var string = 'I do coding';
var string1 = '$string on Geeks for Geeks';
print (string1);
}

Output :

I do coding on Geeks for Geeks.

Dart also allows us to concatenate the string by + operator as well as we can just separate the two strings by Quotes. The concatenation also works over line breaks which is itself a very useful feature.

Dart

var string = 'Geeks''for''Geeks';
var str = 'Coding is ';
var str1 = 'Fun';
print (string);
print (str + str1);

Output :

GeeksforGeeks
Coding is Fun

We can also check whether two strings are equal by == operator. It compares every element of the first string with every element of the second string.

Dart

void main()
{
    var str = 'Geeks';
    var str1 = 'Geeks';
    if (str == str1) {
        print('True');
    }
}

Output : 

True

Raw strings are useful when you want to define a String that has a lot of special characters. We can create a raw string by prefixing it with r . 

Dart

void main() {

  var gfg = r'This is a raw string';
  print(gfg);
}

Output:

This is a raw string
