  <p>I'm developing library. In that I created one class and used it in demo app importing. When I instantiate object of that class then it compiles successfully. But when I try to access getter methods at next line then it gives above error.</p>
  
  <p>I'm not understanding where it's going wrong, because it does not showing any class name or error location.</p>
  
  <p><strong>Can any one help??</strong></p>
