**Lambda functions** are a short and simple way to express tiny functions. Lambda functions are also known as anonymous functions or closures.They are functions without a name that can be used inline within the code.

```dart
return_type var_name = (parameters)=> expression;
```

> **Note**: When using the Lambda function syntax, only one expression can be returned, and it must be a single-line expression.






# Examples
##

}

### How to use a Lambda function to concatenate strings

// Using lambda function

final showData = (String a, String b) => a + b;

main() {
  print(showData("Educative ", "answer"));
}

Finally, if a function only returns one expression, we may use the Lambda function to represent it in only one line. 

How to use Lambda functions in Dart programming

Lambda functions in Dart are anonymous, single-line expressions useful for concise, inline functional programming.
