String interpolation is a powerful feature in Dart that allows you to embed expressions within string literals.
final expression = 'expressions';
print('a string mixing ${"literals"} and ${2 + 1} ${expressions}');
// Prints 'a string mixing literals and 3 expressions'
However, using string interpolation where it is not needed can make the code harder to read and maintain.
final aString = 'a string';
print('$aString'); // Unnecessary string interpolation
It is recommended to use string interpolation only when there is a mix of variables and strings in the same expression.
