+# MyQuran Dart Either
+
+## Either Class Implementation
+
+This Dart code provides an implementation of the `Either` type, a common functional programming pattern. The `Either` type represents a value that can be one of two types: `Right` or `Left`. This is useful for handling operations that can return two types of results, such as a successful value or an error.
+
+### Either<R, L>
+
+An abstract class for values that can be either `Right` or `Left`.
+
+- `fold<B>(B Function(L l) ifLeft, B Function(R r) ifRight)`: Executes one of the given functions based on the type of value.
+
+### Right<R, L>
+
+Represents a `Right` value.
+
+- `Right(this.value)`: Holds the `Right` value.
+- `fold<B>(B Function(L l) ifLeft, B Function(R r) ifRight)`: Executes the `ifRight` function with the `Right` value.
+
+### Left<R, L>
+
+Represents a `Left` value.
+
+- `Left(this.value)`: Holds the Left value.
+- `fold<B>(B Function(L l) ifLeft, B Function(R r) ifRight)`: Executes the `ifLeft` function with the `Left` value.
+
+### Usage
+
+Example usage of `Either`, `Right`, and `Left` classes:
+
+```dart
+void main() {
+  final rightValue = Right<int, String>(42);
+  final leftValue = Left<int, String>('Error');
+
+  final rightResult = rightValue.fold(
+    (error) => 'Left: $error',
+    (value) => 'Right: $value',
+  );
+  print(rightResult); // Output: "Right: 42"
+
+  final leftResult = leftValue.fold(
+    (error) => 'Left: $error',
+    (value) => 'Right: $value',
+  );
+  print(leftResult); // Output: "Left: Error"
+}
+```
