Answer 1

This helps importing use Illuminate\Http\Request; instead of use Request;
use Illuminate\Http\Request;
class UserController extends controller{
}

Answer 2

Change your Controller Function
use Illuminate\Http\Request;
public function postSignUp(Request $request)
{
$email = $request->input('email');
$first_name = $request->input('first_name');
$password = bcrypt($request->input('password'));
$user = new User();
$user->email = $email;
$user->first_name = $first_name;
$user->password = $password;
$user->save();
return redirect()->route('dashboard');
}
public function postSignIn(Request $request)
{
if (Auth::attempt(['email' => $request->input('email'), 'password' => $request->input('password')])) {
return redirect()->route('dashboard');
}
return redirect()->back();
}
