Describe the bug

Hi, In v0.23.2, the GestureDetector doesn't work

It was OK till v0.23.1

Code

import flet as ft


gesture_container:ft.GestureDetector = ft.GestureDetector(
    content=ft.Container(
        width=100,
        height=100,
        bgcolor="blue",
    ),
    on_hover=lambda e: print("hover"),
    on_exit=lambda e: print("exit"),
)

container:ft.Container = ft.Container(
    width=600,
    height=600,
    bgcolor="grey",
    content=gesture_container,
)
def main(page:ft.Page):
    page.add(container)

if __name__ == "__main__":
    ft.app(target=main)

To reproduce

Use the code above. When you exit the GestureDetector zone, an error will be thrown.
