Describe the bug

In order to manage all users file in my flet app I use a filemanager file and request the permission for MANAGE_EXTERNAL_STORAGE in Flet but the application still have a problem.

I tried to grant STORAGE also but I don't know why it get deny every time, I also added

[tool.flet.android.permission]
"android.permission.MANAGE_EXTERNAL_STORAGE" = true
"android.permission.STORAGE" = true

in pyproject.toml

Code sample

filemanager.py

def get_external_storage_directory(self) -> Path:
        storage_dir = os.getenv("EXTERNAL_STORAGE") or os.getenv("HOME")
        if storage_dir is None:
            # Fallback to current directory if no suitable environment variable is found.
            storage_dir = "."
        return Path(storage_dir)
    def get_file_path(self, filename: str) -> Path:
        """Returns the full path of a file."""
        return self.base_path / ("src/" + filename)
    #other function write/read etc...

main.py

ph = ft.PermissionHandler()
page.overlay.append(ph)
page.update()

permission_container = ft.Column()

def request_permissions(e):
    manage_result = ph.request_permission(ft.PermissionType.MANAGE_EXTERNAL_STORAGE)
    storage_result = ph.request_permission(ft.PermissionType.STORAGE)

    if manage_result and storage_result:
        #permission_container.controls.clear() 
        page.add(ft.Text(f"Requested MANAGE_EXTERNAL_STORAGE: {manage_result}"))
        page.add(ft.Text(f"Requested STORAGE: {storage_result}"))
        page.update()
    else:
        page.add(ft.Text("Failed to grant required permissions."))
