Describe the bug

On macOS the filepicker doesn't open. On android it opens but show an error when I choose a photo.

Code sample

Code

import flet as ft

def main(page: ft.Page):
    def pick_files_result(e: ft.FilePickerResultEvent):
        if e.files:
            print("Ficheiro(s) selecionado(s):", [f.path for f in e.files])
        else:
            print("Nenhum ficheiro selecionado.")

    file_picker = ft.FilePicker(on_result=pick_files_result)
    page.overlay.append(file_picker)

    def open_picker(e):
        print("DEBUG: Botão clicado, a chamar pick_files...")
        file_picker.pick_files(
            allow_multiple=True, # Vamos permitir múltiplos para teste
            dialog_title="Teste do Seletor"
        )
        page.update()
        print("DEBUG: Chamada a pick_files concluída.")

    page.title = "Teste do FilePicker"
    page.vertical_alignment = ft.MainAxisAlignment.CENTER
    page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
    page.add(
        ft.ElevatedButton("Abrir Seletor de Ficheiros", on_click=open_picker)
    )

ft.app(target=main)
