title: How to delete all the boxes in Hive Flutter?
body: <p>I am developing an application using Flutter; it will store some data locally, so I decided to use Hive package which was really amazing package to store data. So now I will store all the data locally when the user press the sync button. After that, if the user clicks sync again, I have to delete all the boxes and store data which may or may not have the same box name.<br />
  I don't want to increase the application storage to increase if the sync button is clicked, I want to delete all the boxes and again I want to create the box.</p>
