Control Refs declarations

[pamoroso]

In the Flet documentation, the Getting started section of the Python Guide also discusses Control Refs.

I understand the rationale behind Control Refs and how they are used. But, as a beginner, what a Control Ref declaration is supposed to mean in Python eludes me. For example, in this code:

first_name = Ref[TextField]()

is the right hand side of the assignment indexing a Ref list and calling the resulting item? Is it a type declaration? Something else?

Ref is a generic type. Take a look at its sources: https://github.com/flet-dev/flet/blob/main/sdk/python/flet/ref.py
Ref[TextField]() in Python means the same as List<string>() in C#. Well, in Python it's just for type hinting, so IDE know what members to show when you type first_name.current. :)

Looks like a good article: https://medium.com/@steveYeah/using-generics-in-python-99010e5056eb

Thanks, I'm not yet familiar with Python type hints.
