Dart String Interpolation
Dart String Interpolation
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 for manipulating strings and creating new strings by adding another value. It can also be used to evaluate strings, 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.
/*
Dart String Interpolation demo Program
Dart Tutorials – www.TestingDocs.com
*/
void main()
{
// declare a variable
String websiteName = “TestingDocs.com”;
// String interpolation using ${expression}
print(“Welcome to ${websiteName}”);
}
In this example, we have declared one String variable that holds a string value and then we printed the result using the string interpolation.
