setMessageForObject method

void setMessageForObject(
  1. Object object,
  2. String? value
)

Sets the message for the object equal to the value passed in and notifies Listeners If you're using a primitive type the value SHOULD NOT BE CHANGED, since Hashcode uses == value

Implementation

void setMessageForObject(Object object, String? value) {
  _messageStates[object.hashCode] = value;
  notifyListeners();
}
