Infinite layout widgets like lists, grids...

Infinite list

InfiniteListView has same attributes as a normal flutter ListView widget.

InfiniteListView.separated(
        itemBuilder: (context, index) {
          return Text('$index', style: TextStyle(color: Colors.red, fontWeight: FontWeight.bold));
        },
        itemCount: _data.length, // Current itemCount you have
        hasNext: _data.length < 200, // let the widget know if you have more data to show or not
        nextData: this.loadNextData, // callback called when end to the list is reach and hasNext is true
        separatorBuilder: (context, index) => Divider(height: 1),
      ),
    );

You can specify the last loading row by providing loadingWidget.

You can interact with the trigger to load additional data by default it's 300 but you can override it with scrollThreshold.

Infinite grid

InfiniteGridView has same attributes as a normal flutter GridView widget.

InfiniteGridView(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 4),
        itemBuilder: (context, index) {
          return Text('$index', style: TextStyle(color: Colors.white));
        },
        itemCount: _data.length, // Current itemCount you have
        hasNext: _data.length < 200, // let the widget know if you have more data to show or not
        nextData: this.loadNextData, // callback called when end to the list is reach and hasNext is true
      ),
    );

You can specify the last loading row by providing loadingWidget.
