Memento Shape Editor #29
Description
Based on the Java example from the book, implement the Memento pattern.
Features/Problems:
- This sample includes FlutterAdapter example for adapting classic application to flutter platform.
-
There is no analogue of ObjectInputStream in Dart, so it will need to be implemented as an additional library. -
So far, I don't understand the purpose of the HistoryPair class. - Perhaps add a list of undoes to the right of the window.
