PasteNodeIntent constructor

The const PasteNodeIntent(); statement is creating an instance of the PasteNodeIntent class using a const constructor. This means that the instance of PasteNodeIntent is a compile-time constant, which can help with performance optimizations and memory efficiency. By using const, Dart ensures that only one instance of PasteNodeIntent is created and reused whenever needed, rather than creating a new instance every time it is referenced. This can be beneficial in terms of reducing memory usage and improving performance in your Dart code.
