# Arrow Function

* Dart has a special syntax for the function body, which is only one line. The arrow function is represented by **\=&gt;** symbol. It is a shorthand syntax for any function that has only one expression.
    

### **Syntax**

returnType functionName(parameters...) => expression;
```

* By using fat arrow =&gt; the curly brackets needs to be removed. Otherwise, the code editor will show you an error.
    
* If a function has a return type then by using a Fat arrow it is required to **remove the return keyword**.
    

## ShortHand

* Short hand expression is used to define a single expression in a function.
