+In Dart, the **`.addFirst()`** method adds an element at the beginning of a `Queue`. This method is part of the `Queue` class under the `dart:collection` library.
+
+## Syntax
+```pseudo
+queue.addFirst(element);
+```
+
+**Parameters:**
+
+- `element`: The element to be added at the beginning of the queue.
+
+**Return value:**
+
+This method does not return a value.
+
+## Example
+
+The following example demonstrates the usage of the `.addFirst()` method:
+```dart
+import 'dart:collection';
+
+void main() {
+  Queue<int> numbers = Queue<int>();
+  numbers.add(20);
+  numbers.add(30);
+  numbers.add(40);
+
+  print("Original queue: $numbers");
+
+  numbers.addFirst(10);
+  print("After addFirst(10): $numbers");
+
+  numbers.addFirst(5);
+  print("After addFirst(5): $numbers");
+}
+```
+
+The output for the above code is as follows:
+```shell
+Original queue: {20, 30, 40}
+After addFirst(10): {10, 20, 30, 40}
+After addFirst(5): {5, 10, 20, 30, 40}
+```
