MainContextexample, we're going to add some blocks and explain how each of them would capture and process an incoming message or event:
postbackand returns two parameters. The
ref(for Messenger) or
any_numberis called (even first) and its execution condition matches with the message (which is a number), this will not be executed.
keyword "1"block will be executed, because it has a higher execution priority than
any_numberblock, and with the execution of the first one, the matching process will be stopped.
any_numberblock will be executed too.
