Dart String Interpolation

Overview

Dart String interpolation is the process of embedding variables or expressions within a string, making it easy to create dynamic strings.

String Interpolation

String interpolation is a technique to manipulate the string and create a new string by adding another value. It can be used to evaluate the string including placeholders, variables, and interpolated expressions.

${expression}

We can use the ${expression} syntax to interpolate values directly into a string. The expressions are replaced with their corresponding values.

Example

We can use the string interpolation as a placeholder to replace the actual values during the runtime of the program. Using ${expression} inside a string.

Let’s understand string interpolation by an example.

// declare a variable
String websiteName = “TestingDocs.com”;
// String interpolation using ${expression}
print(“Welcome to ${websiteName}”);
