Dart also supports a nice shorthand syntax for any function that has only one expression. In other words, is the code inside the function block only one line? Then it's probably a single expression, and you can use this syntax to be concise:
<pre><code class="lang-dart">String makeGreeting(String name) =&gt; 'Hello, $name!';

main() {
 print(makeGreeting('Wallace'));
}
</code></pre>
For lack of better term, we'll call this an arrow function. Arrow functions implicitly return the result of the expression. <code>=&gt; expression;</code> is essentially the same as <code>{ return expression; }</code>. There's no need to (and you can't) include the <code>return</code> keyword.

For lack of better term, we'll call this an *arrow function*. Arrow functions implicitly return the result of the expression. `=> expression;` is essentially the same as `{ return expression; }`. There's no need to (and you can't) include the `return` keyword.
