googleApiKey

Returns an Optional that contains a string representing the Google API key or an empty Optional if the Google API key was not set.

Some Chromium features such as Geolocation, Spelling, Speech, etc. use Google APIs, and to access those APIs, an API Key, OAuth 2.0 client ID, and client secret are required. Setting up API keys is optional. If you do not do it, the specific APIs using Google services won't work.
