unfreeze method

@override void unfreeze()

Function used to unfreeze state.

When this function is called, the state of the desired object is unpaused, and so state changes can now be implemented.

Implementation

@override
void unfreeze() {
  componentState.unfreeze();
  for (var element in watchers) {
    element.unfreeze();
  }
  _frozen = false;
}
