Create a Flutter widget cloning class

Request details: I'm looking for a utility class that takes in a flutter widget and copies all non null properties to a new one. This can be done with a mapper but I want to be able to do this across multiple widgets and mappers would be inefficient. Requests: Use this library [login to view URL] and example usage [login to view URL] supports deep cloning prefer a single function that accepts a generic input I have done a quick look at solving this and can provide an initial overview of the hurdles I faced. Prefer a developer that has some working knowledge of compiler and optimization as the initial solution will not be efficient. Deliverables: A dart file that takes a widget as input and creates a copy of it using reflection
