sendEvent method
Send information about client events.
Ask the analysis server to include the fact that an action was performed
in the client as part of the analytics data being sent. The data will only
be included if the sending of analytics data is enabled at the time the
request is processed. The action that was performed is indicated by the
value of the action field.
The value of the action field should not include the identity of the
client. The analytics data sent by server will include the client id
passed in using the --client-id command-line argument. The request will
be ignored if the client id was not provided when server was started.
Implementation
Future sendEvent(String action) =>
_call('analytics.sendEvent', {'action': action});
