Scrolling is buggy in this lib. Please have a look at it.

Sometimes when I Scroll over widget list the scrolling doesn't work. I have to move my hands on it 2 or 3 times to scroll over it.

Hello,

Thanks for your widget. I like it and use in my project :)

I think you should change plugin type to "Dart Package". Because you don't need kotlin/java or objc-swift code.

Please see: https://flutter.dev/docs/development/packages-and-plugins/developing-packages#package-types

return AlphabetListScrollView( strList: _names!, highlightTextStyle: const TextStyle( color: Colors.yellow, ), showPreview: true, itemBuilder: (context, index) { return ListTile(title: Text(_names![index])); }, indexedHeight: (i) { return 80; }, keyboardUsage: true, headerWidgetList: [ AlphabetScrollListHeader(widgetList: [ Padding( padding: const EdgeInsets.all(16.0), child: TextFormField( decoration: const InputDecoration( border: OutlineInputBorder(), suffix: Icon( Icons.search, color: Colors.grey, ), labelText: "Search", ), ), ) ], icon: const Icon(Icons.search), indexedHeaderHeight: (index) => 80), ], ); }

its showing error like "RangeError (index): Invalid value: Valid value range is empty: 0"

I Tried the example app and the scrolling using the alphabets doesn't work.

Hello all!

Thanks for your interest in using this package. I understand that I haven't address quite a few issues and there are pull requests that I haven't look at. Very sorry for the inconveniences.

Anyway, I like to get your opinions!

Right now there is another flutter package that does the same thing. Here's the link https://github.com/flutterchina/azlistview. Do try it out and let me know if it works well! I'll probably going to develop a feature for my app with the a to z scroll view in the next couple of weeks. So I will see if the aslistview is really a superior a-z view that does what I want plus more. If it is, I'll deprecate and freeze this project. If not, I will continue with this project.

I'm only but a man. Please do contribute with pull requests and bug fixes. If you want to take over this project. Do let me know as well. :)

This flag allows you to enable or disable the use of vibration. In addition to giving more control to the plugin, it allows use on platforms that do not support this feature.

Hello @LiewJunTung

Thanks for this awesome package.

As per current implementation, the alphabet list view is fixed to the right. My use case requires the listview be aligned to the left of the screen, but I've tried that in vain.

Is there a way you can add more alignment customization?
