Reference documentation and code samples for the Dialogflow v3 API class Form.
A form is a data model that groups related parameters that can be collected
from the user. The process in which the agent prompts the user and collects
parameter values from the user is called form filling. A form can be added to
a [page][google.cloud.dialogflow.cx.v3.Page]. When form filling is done, the
filled parameters will be written to the
[session][google.cloud.dialogflow.cx.v3.SessionInfo.parameters].
