     * **Reusable Implementations:**
-        * If the Java/Kotlin code defines a class that `implements` an interface, To translate it to Dart make this class to be 'final class with' \$InterfaceName, as JNIgen make a mixin class \$InterfaceName that handles this, Don't make it to implements InterfaceName only use the mixin class.

     * **Asynchronous Listener Methods:**
         * For `void`-returning methods in implemented interfaces that should be non-blocking (listeners), explicitly set the `<methodName>\$async` parameter to `true` when using the inline implementation (e.g., `run\$async: true`).
         * If using a reusable class (mixin), override the `<methodName>\$async` getter to return `true` (e.g., `bool get run\$async => true;`).
