How to Handle Firebase Auth exceptions on flutter

Question

Please does anyone know how to catch firebase Auth exceptions on flutter and display them?

Note: I am not interested in the console (catcherror((e) print(e))

   try {
  final newuser = await _auth.createUserWithEmailAndPassword(
      email: emailController.text, password: passwordController.text);
  // print("Done");
} catch (e) {
  print(e);
  showDialog(
    context: context,
    builder: (BuildContext context) {
      return AlertDialog(
        title: new Text(e.message),
        actions: [
          FlatButton(
            child: new Text("OK"),
            onPressed: () {
              Navigator.of(context).pop();
            },
          ),
        ],
      );
    },
  );
}
