next method
Chains the current middleware with a nextMiddleware function and returns
a new middleware handler that applies the current middleware followed by
the nextMiddleware.
This method allows you to create a new middleware handler that chains the
behavior of the current middleware and the nextMiddleware, forming a
sequence of middleware to process requests in the specified order.
Implementation
Middleware next(Middleware nextMiddleware) {
Handler middleware(Handler handler) {
return this(nextMiddleware(handler));
}
return middleware;
}
