The name of the variable. This must be unique across variables and procedures.
opt_type
string | null
(Optional) The type of the variable like 'int' or 'string'. Does not need to be unique. Field_variable can filter variables based on their type. This will default to '' which is a specific type.
opt_id
string | null
(Optional) The unique ID of the variable. This will default to a UUID.
