The Cross Platform Call Detection Plugin enables applications to determine whether a user is currently engaged in an active call on Android or iOS devices. The plugin supports detection of both standard cellular voice calls and WhatsApp voice calls, returning a boolean value that can be used to control application workflows, pause specific operations, manage user interactions, enhance security checks, or prevent interruptions while a call is in progress. Designed for seamless integration with mobile applications, it provides a simple and reliable way to make applications aware of the user's call status in real time.
