/**
* @file example_event_loop_multi.c
* @brief Example application that demonstrates multiple primitives used with two FuriEventLoop instances.
*
* This application simulates a complex use case of having two concurrent event loops (each one executing in
* its own thread) using a stream buffer for communication and additional timers and message passing to handle
* the keypad input. Additionally, it shows how to use thread signals to stop an event loop in another thread.
* The GUI functionality is there only for the purpose of exclusive access to the input events.
*
* The application's functionality consists of the following:
* - Print keypad key names and types when pressed,
* - If the Back key is long-pressed, a countdown starts upon completion of which the app exits,
* - The countdown can be cancelled by long-pressing the Ok button, it also resets the counter,
* - Blocks of random data are periodically generated in a separate thread,
* - When ready, the main application thread gets notified and prints the data.

* @brief GUI: ViewDispatcher API
*
* ViewDispatcher is used to connect several Views to a Gui instance, switch between them and handle various events.
* This is useful in applications featuring an advanced graphical user interface.
*
* Internally, ViewDispatcher employs a FuriEventLoop instance together with two separate
* message queues for input and custom event handling. See FuriEventLoop for more information.
*
* If no multi-view or complex event handling capabilities are required, consider using ViewHolder instead.
*
* @warning Views added to a ViewDispatcher MUST NOT be in a ViewStack at the same time.
