public final class Flow extends GeneratedMessageV3 implements FlowOrBuilder
Flows represents the conversation flows when you build your chatbot agent.
A flow consists of many pages connected by the transition routes.
Conversations always start with the built-in Start Flow (with an all-0 ID).
Transition routes can direct the conversation session from the current flow
(parent flow) to another flow (sub flow). When the sub flow is finished,
Dialogflow will bring the session back to the parent flow, where the sub flow
is started.
Usually, when a transition route is followed by a matched intent, the intent
will be "consumed". This means the intent won't activate more transition
routes. However, when the followed transition route moves the conversation
session into a different flow, the matched intent can be carried over and to
be consumed in the target flow.

getEventHandlers(int index)
public EventHandler getEventHandlers(int index)
A flow's event handlers serve two purposes:
- They are responsible for handling events (e.g. no match,
webhook errors) in the flow.
- They are inherited by every page's event
handlers, which can be used to handle common events
regardless of the current page. Event handlers defined in the page
have higher priority than those defined in the flow.
Unlike transition_routes, these handlers are
evaluated on a first-match basis. The first one that matches the event
get executed, with the rest being ignored.
