# string\_jnterpolation

* Here, `$variableName` is used to join variables.
* This joining process in Dart is called string interpolation.
*
* **String Interpolation** is the act of adding a variable into a string, making sure it gets evaluated when the string does.
*
* It differs from **string concatenation** in that it dynamically injects the value of the variable into the string.
