Most popular and easy to use open source UI library with 1000+ Widgets to build flutter app.

Describe the bug

Error: Unexpected null value. at Object.throw_ [as throw] (http://localhost:51605/dart_sdk.js:4332:11) at Object.nullCheck (http://localhost:51605/dart_sdk.js:4662:30) at page_view.PageController.new.nextPage (http://localhost:51605/packages/flutter/src/widgets/page_view.dart.lib.js:366:38) at http://localhost:51605/packages/getwidget/components/carousel/gf_carousel.dart.lib.js:1031:38 at http://localhost:51605/dart_sdk.js:23808:9

Can't get social icons and brand color

GFButton( onPressed: (){}, text: "primary", icon: Icon(Icons.share), ),

Better if icon installation and list is provided.

Working fine in stable version after moving to beta and starting web app getting following error.

../flutter/.pub-cache/hosted/pub.dartlang.org/getwidget-1.2.2/lib/components/appbar/gf_appbar.dart:312:57: Error: No named parameter with the name 'nullOk'. final ScaffoldState scaffold = Scaffold.of(context, nullOk: true);
^^^^^^
../flutter/packages/flutter/lib/src/material/scaffold.dart:1918:24: Context: Found this candidate, but the arguments don't match. static ScaffoldState of(BuildContext context) {

I noticed that the active page indicator is not being updated without explicitly call setState on onPageChanged callback.

Currently, if I need to update the active page indicator, I have to use GFCarousel inside a stateful widget and set onPageChanged,

onPageChanged: (index){
        setState(() {});
},

Describe the bug Not able to run the application with the latest version of flutter. Getting Below compile-time error.

Using version 2.0.1-nullsafety.4 on ios simulator.

missing initialIndex property setter in first example. property inActiveColor: is a mismatch with actual property of the widget, inactiveColor: This affects the second example too. One of them is a typo.

introScreenBottomNavigationBar: GFIntroScreenBottomNavigationBar( does not show. Reverting back to version 1.2.4 without any code changes will make the Bottom navigator show.

To recreate, use the 2.0.1 version, copy and paste your example code from https://docs.getwidget.dev/gf-intro-screen/ and give it a try.

Describe the bug Add GFAccordion as a child of SimpleDialog, when it's collapsed, its width is the default SimpleDialog width. When accordion expanded, the width is much larger to reach the insetPadding of dialog.

Expected behavior The expanded width should be the same as collapsed.

Screenshots Collapsed Expanded Expanded: after deleting width: MediaQuery.of(context).size.width https://github.com/ionicfirebaseapp/getwidget/blob/9bceb782716bb5926d5dd488de1cdaca7af3ae61/lib/components/accordian/gf_accordian.dart#L160

Additional the file name and folder name should be accordion rather accordian?

It's down since yesterday. Is there other way we can view the documentation or perhaps include the source code in the app itself and not just the link of the docs site.

The way the height of a items container of GFItemsCarousel is calculated does not make sense at all and prevents users from creating thin carousels. In the code the height is set to size but this is related to the width of the item container. Do I miss something?

Here size is set to account for the width of the items container.

https://github.com/ionicfirebaseapp/getflutter/blob/75ca1fbe26169362d5c5ee207a9e503b208b02d3/lib/components/carousel/gf_items_carousel.dart#L88

  @override
  void initState() {
    offset = 0;
    animationController = AnimationController(
      duration: const Duration(milliseconds: dragAnimationDuration),
      vsync: this,
    );
    Future.delayed(Duration.zero, () {
      setState(() {
        final double localWidth = MediaQuery.of(context).size.width;
        width = localWidth;
        size = width / widget.rowCount;
      });
    });
    super.initState();
  }

But then in the build function:

https://github.com/ionicfirebaseapp/getflutter/blob/75ca1fbe26169362d5c5ee207a9e503b208b02d3/lib/components/carousel/gf_items_carousel.dart#L183

  Widget build(BuildContext context) => GestureDetector(
        onHorizontalDragStart: onSlideStart,
        onHorizontalDragUpdate: onSlide,
        onHorizontalDragEnd: onSlideEnd,
        child: Container(
          width: double.infinity,
          height: size,
          child: Stack(
            children: [
              Positioned(
                left: offset,
                child: Row(
                  children: widget.children
                      .map((child) => Container(
                            width: size,
                            height: size,
                            child: child,
                          ))
                      .toList(),
                ),
              ),
            ],
          ),
        ),
      );

Describe the bug

when i use following code ,hot reload not work, button text not change when model.reading has been changed

GFButton(
                    child: model.reading ? Text('Stop') : Text('Continuous'),
                    onPressed: () async {
                      if (!model.reading) {
                        await model.startInventory();
                      } else {
                        await model.stopInventory();
                      }
                    },
                  ),

i must set a key for that to work

GFButton(
                    key: ValueKey(model.reading),
                    //text: model.reading ? 'Stop' : 'Continuous',
                    child: model.reading ? Text('Stop') : Text('Continuous'),
                    onPressed: () async {
                      if (!model.reading) {
                        await model.startInventory();
                      } else {
                        await model.stopInventory();
                      }
                    },
                  ),

is that expected?

I'm using the lib for a web application and the GFCarrousel component doesn't recognize the mouse click, when trying to drag an item from the list it remains unchanged.

Is your feature request related to a problem? Please describe. This is just a suggest enhancement on the GF List tile

Describe the solution you'd like Would like to have an option on the GFList tile to have a row of at least two text button or tags in the bottom row

Describe alternatives you've considered I have explored using the card, option and I still find/think it would be neater to have this functionality has party of the GF List tile
