reportError method

  1. @protected
void reportError ({String context, dynamic exception, StackTrace stack, InformationCollector informationCollector, bool silent: false })
@protected

Calls all the registered error listeners to notify them of an error that occurred while resolving the image.

If no error listeners are attached, a FlutterError will be reported instead.
