FlutterLazyLoader<T> class Null safety

Lazy loading list for flutter

Takes a dataLoader and a listTile as parameters

The dataloader is used for loading more data into the list. Should the dataloader-function return an empty list it is assumed that this is the end of the data and no more will be loaded.

The listTile is the Widget that will be rendered for each data in the list
