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,
  physics: null,
  shrinkWrap: false,  

  /// ListView Padding
  topPad: 0.0,
  btmPad: 0.0,
  topPadOnMaxHeight: 20.0,
  btmPadOnMaxHeight: 70.0,

  /// Shader Effect
