Description

Fixing issue with unsafe reading of event.data['name']

Detected when integrating firebase auth. We get event data that falls through the checks in _registerEvents and does not follow the expected format.

Looks good to me.

Might be safer to scope only the event parsing, to avoid catching something unrelated triggered by processEvents in the future.

UnityWebEvent? webEvent;
try {
  webEvent = UnityWebEvent(
    name: event.data['name'],
    data: event.data['data'],
  );
} catch (e) {
 ...
}

if(webEvent != null) {
  _processEvents(webEvent);
}
