title: When and how should I use GetStorage.init(); with the get_storage package in flutter
body: <p>I saw that most people use GetStorage.init(); in the first main() function of their projects like:</p>
  <pre><code>main() async {
    await GetStorage.init();
    runApp(App());
  }
  </code></pre>
  <p>What if I call this function more often? When is the main function even called? When I started the App the first time? I want to understand when and how to call the GetStorage.init() function, and what the difference is when I only call it on a specific container like</p>
  <pre><code>GetStorage.init('MyStorage'); 
  </code></pre>
  <p>I couldn't print something after quitting the app to test the behavior.</p>
