Try this:

    def close(e, view, path, page):
        def f(f):
            removejson(path="./datas/settings.json", value=path, subject="indexfolder")
            container = f.control.parent.parent # https://python.plainenglish.io/access-any-controls-parent-flet-98e2c60dfab8
            container.parent.controls.remove(container)
            f.page.update()
        return f
