Version:

Since:
  • 1.2.0
This class provides functions for adding pull to refresh functionality to any container element which hosts refreshable content. By default this class will generate default panel, which consists of the refresh icon, primary, and secondary text. The application can use the callback to provide their own panel. When the release happens, the refresh function will be invoked and application should use this to execute any logic required to refresh the content inside the panel. For example, fetching new cotent for the ListView inside the container. The application must resolve or reject the Promise so that this class can do the neccessary cleanup.
