removeObserver method

  1. @override
void removeObserver(
  1. CellObserver observer
)
override

Remove an observer that was previously registered with addObserver.

If addObserver was called more than once for observer, removeObserver must be called the same number of times before observer is removed.

Once removed observer is not called again.

If observer is not a registered observer of the cell, this method does nothing.

Implementation

@override
void removeObserver(CellObserver observer) {}
