postEvent method Null safety

  1. @protected
void postEvent(
  1. String eventKind,
  2. Map<String, dynamic> eventData

All events dispatched by a BindingBase use this method instead of calling developer.postEvent directly so that tests for BindingBase can track which events were dispatched by overriding this method.


void postEvent(String eventKind, Map<String, dynamic> eventData) {
  developer.postEvent(eventKind, eventData);
