//This code is for an ESP32 board that connects to a WiFi network and sets up a web server.
// It listens for POST requests on the "/uri" endpoint and expects a parameter named "uri" in the request body.
// When a request is received, it prints the URI to the Serial Monitor and sends a response back to the client.

//The Flutter app can send a POST request to the ESP32's IP address with the URI as a parameter in the request body.
