+    **Interop** (short for _interoperability_) refers to Dart's ability to
+    communicate and work with code written in other programming languages.
+
+    In Dart, interop is commonly used to:
+
+    - Call native code written in languages like C, C++, or Rust.
+    - Interact with platform-specific APIs.
+    - Reuse existing libraries that aren't written in Dart.
+
+    Dart provides different interop mechanisms
+    depending on the platform and use case.
+    For example, Dart applications can use the
+    Foreign Function Interface (FFI) to call native libraries, or
+    platform-specific interop layers when running on Flutter or the web.
