ExceptionHandler typedef

Future<Response> ExceptionHandler (Request r, Object ex, StackTrace st)

Exception/error handler function type.

Define server exception handlers or pipeline exception handlers matching this type.

The ex is Object because these methods are expected to handle anything that can be thrown or raised in Dart. This includes Error and Exception, but can be any type of object.

Used for Server.exceptionHandler and ServerPipeline.exceptionHandler.
