ParseLiveGridWidget<T extends ParseObject> class

A widget that displays a live grid of Parse objects.

The ParseLiveGridWidget is initialized with a query that retrieves the objects to display in the grid. The gridDelegate is used to specify the layout of the grid, and the itemBuilder function is used to specify how each object in the grid should be displayed.

The ParseLiveGridWidget also provides support for error handling and refreshing the live list of objects.
