Describe the requested feature

I would like that in such elements as row, columns and so on it would be possible:

1. add an element as in `page.add()
2. use __contains__ method

column = ft.Column()

column.add(
    text
)

print(text in column)

Suggest a solution

# add element in column
def add(self, control):
    self.controls.append(control)
    self.update()

Additional details

This is a good way to bring the library to the same syntax, instead of using page.add() or column.controls.append().
