Detect change between two stateflow

I would like to determine if two state machines are different. I would like to be able to analyze their content for example because parameters accessible from a get_param() are not enought.

Is there a unique identifier for the state machines which increments when modified or even a state machine version number?

Thanks in advance

Are you looking for https://www.mathworks.com/help/simulink/model-comparison.html

No I don't want to compare full model. I just want to know quickly, without open my stateflow blocks if there is change inside ?

[Fangjun Jiang]

You have to have a base to compare with, right? Assume you have a model saved in a file (.mdl or .slx), and you have another file (.mdl or .slx, assume the content is similar to the other model), you want to know in particular that a Stateflow chart inside is different, without even open the model in Simulink?

The two model are open and in front of me and I'd like to see without looking inside chart block if there is a change. Maybe with a version parameter or a last save date...

[Fangjun Jiang]

I don't think there is a practical solution for it now. Version parameter and save date, or the dirty flag, only applies to the model, not to a block. I checked the callback function, there is no such a function related to this, for example, 'ChangeFcn'.
