T value

Returns the current value

Implementation

T get value {
  RxInterface.proxy?.addListener(subject);
  return _value;
}
void value=(T val)

Updates the value and adds it to the stream, updating the observer Widget, only if it's different from the previous value.

Implementation

set value(T val) {
  if (subject.isClosed) return;
  if (_value == val && !firstRebuild) return;
  firstRebuild = false;
  _value = val;

  subject.add(_value);
}
