Column(
  mainAxisAlignment: MainAxisAlignment.center,
  children: [
    signInButton(
      context,
      () {
        Navigator.of(context).push(MaterialPageRoute(
          builder: (context) => const HomeScreen(),
        ));
      },
      child: const Text("Toast Message"),
    ),
  ],
)

When I press the button, the application stops and shows this line of code.

You have to use use showtoast on press of the button
