String interpolation in Dart involves embedding variables or expressions within a string, facilitating the creation of dynamic strings. The syntax uses a dollar sign and curly braces, like `${variable}`. Here's a simple example:

```dart

String name = 'John';

int age = 25;

String message = 'My name is $name and I am $age years old.';

```

In this example, the values of `name` and `age` are inserted into the string using string interpolation. The resulting `message` will be "My name is John and I am 25 years old." [2] [5] [10]
