Hello, budding developer! In today's lesson, we delve into a critical concept in Dart: String Interpolation. Interpolation allows us to insert variables directly into a string. We will begin by defining string interpolation before branching into various ways to deploy it in Dart. Following these foundational learnings, we will conclude by providing insights to help navigate common pitfalls when using string interpolation.

Think of string interpolation as a method of embedding variables inside a string. Assume that we have two strings: "Neil" and "Armstrong". We can interpolate these into one string, "Neil Armstrong". Here is how it's done:

The $ symbol allows us to combine firstName, a space, and lastName to form the fullName string. Seems familiar? Indeed! We have implicitly applied this technique in our print statements earlier in the course.

In Dart, we can interpolate different types of variables into a string. Here's an example:

The interesting part here is that Dart flawlessly converts the integer into a string before performing the interpolation. Quite handy, wouldn't you agree?
