Description:

last focused listview

last_focused_listview #

This Flutter package, last_focused_listview, provides a way to render a ListView widget efficiently starting with the last item in the data list. If you want to use lazy-loading and starting with the last item, without scroll jump or animate, This package will help you.
**If you use scroll jump or animate to move to the last item, your itemBuilder method will be called for every items in the data list.



Usage #
You can use LastFocusedListView() and AutoConvertListView() in this package. If your itemTile's height is variable, AutoConvertListView() will be good choice.

AutoConvertListView() automatically transforms a regular ListView widget into
a LastFocusedListView() widget based on the convertCount parameter.


A simple usage example of LastFocusedListView() :
import 'package:last_focused_listview/last_focused_listview.dart';

LastFocusedListView(
itemList: List.generate(100, (index) => index), // your data list
itemHeight: 35.0, // height of your single itemTile
maxHeight: maxHeight, // max height of this widget
itemBuilder: (item) => Tile(item: item), // your itemTile build logic
),

/// other params
LastFocusedListView(
...
controller: null,

shrinkWrap: false,

/// ListView Padding
topPad: 0.0,
btmPad: 0.0,
topPadOnMaxHeight: 20.0,
