Enables stats collection in ML Kit vision. The stats include API call counts, errors, API call
durations, options, etc. No personally identifiable information is logged.
The setting is per FirebaseApp, and therefore per Vision, and it is persistent across
launches of the app. It means if the user uninstalls the app or clears all app data, the setting
will be erased. The best practice is to set the flag in each initialization.
By default the logging is enabled. You have to specifically set it to false to disable
logging.
Gets an instance of Firebase Vision service for the default Firebase app. The default Firebase
app instance must be configured before calling this method; otherwise, raises FIRAppNotConfigured
exception.
Declaration
Swift
classfuncvision()->Self
Return Value
A Firebase Vision service instance, initialized with the default Firebase app.
