The **`map.remove()` function** in Dart removes a specific element (key-value pair) from the map.

>- If the key is found in the map, the key-value pair is removed and the key is returned.
>- If the key is not found in the map, `null` is returned.

The illustration below shows the visual representation of the `map.remove()` function:


#   
## Syntax
```dart

```

>  `map_name` is the name of the queue.

## Parameter

## Return value

The Dart function `map.remove()` removes a specific element (key-value pair) from a map.

# Code
The following code shows how to use the `map.remove()` function in Dart:


import 'dart:convert';

void main() {
  var map = new Map();

  map [1] = 'Tom';
  map [2] = 'Alsvin';
  map [3] = 'Eddie';
  //map containg key value pairs before remove
  print("map elements before remove: ${map}");

  //map after remove 3rd element
  print("The value against 3rd element: ${map.remove(3)}");
  print("map elements after remove: ${map}");

}
