This can be your signin function with email and password as of Sept 2020.Initialze app is a new introduced method we must at least call once before we use any other firebase methods.

 Future signin() async {
    final formState = _formkey.currentState;
    await Firebase.initializeApp();
    if (formState.validate()) {
      setState(() {
        loading = true;
      });
      formState.save();
      try {
        print(email);
        final User user = (await FirebaseAuth.instance
                .signInWithEmailAndPassword(email: email, password: password))
            .user;
      } catch (e) {
        print(e.message);
        setState(() {
          loading = false;
        });
      }
    }
  }
