Dart String is a sequence of the character or UTF-16 code units. It is used to store the text value. The string can be created using single quotes or double-quotes. The multiline string can be created using the triple-quotes. Strings are immutable; it means you cannot modify it after creation.<\/p>\n\n\n\n
In Dart, The String<\/strong> keyword can be used to declare the string. The syntax of the string declaration is given below.<\/p>\n\n\n\n The\u00a0print()<\/strong>\u00a0function is used to print the string on the screen. The string can be formatted message, any expression, and any other object.\u00a0Dart\u00a0provides\u00a0${expression},<\/strong>\u00a0which is used to put the value inside a string. Let’ have at look at the following example.<\/p>\n\n\n\n Example –<\/strong><\/p>\n\n\n\n <\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n The\u00a0+ or += operator<\/strong>\u00a0is used to merge the two string. The example is given below.<\/p>\n\n\n\n <\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n The string interpolation is a technique to manipulate the string and create the new string by adding another value. It can be used to evaluate the string including placeholders, variables, and interpolated expression. The\u00a0${expression}<\/strong>\u00a0is used for string interpolation. The expressions are replaced with their corresponding values. Let’s understand by the following example.<\/p>\n\n\n\n <\/a><\/a><\/a><\/p>\n\n\n\n Output:<\/strong><\/p>\n\n\n\n Explanation –<\/strong><\/p>\n\n\n\n In the above code, we have declared two strings variable, created a new string after concatenation, and printed the result.<\/p>\n\n\n\n We have created two variables that hold integer value then performed the mod operation and we printed the result using the string interpolation.<\/p>\n\n\n\n We can use the string interpolation as a placeholder, as we have shown in the above example.<\/p>\n\n\n\n The Dart provides the following string properties.<\/p>\n\n\n\n The Dart provides an extensive range of methods. The list of a few essential methods is given below.<\/p>\n\n\n\n Dart String is a sequence of the character or UTF-16 code units. It is used to store the text value.
