Solution

TextField --> TextFormField

wrap all TextFormField with a Form and give a key

https://docs.flutter.dev/cookbook/forms/validation

Form(
              key: formKey,
              child: Column(
                children: [
                  const Text(
                    'Please log in to your account in order to interact with and create notes and talk friends',
                  ),
                  EmailTextFormField(emailController: emailController),
                  PasswordTextFormField(passwordController: passwordController),
                  LoginButton(emailController: emailController, passwordController: passwordController),
                  const ForgotPasswordButton(),
                  const SignInWithGoogleButton(),
                  const NotRegisterYetButton()
                ],
              ),
            ),
