Usage

If you are starting a new complex flutter app and need to build up your base widgets by the easiest way you will need to use app_fundamentals plugin. this is the available widgets you can try.

Add the dependency to your project and start using app_fundamentals #

dependencies:
   app_fundamentals : ^0.0.15

Importing the package #

import 'package:app_fundamentals/app_fundamentals.dart';

Examples

lets take for example the usage of BaseStatefulWidget if you extend BaseStatefulWidget to build your screen you can override multiple methods to easy create new screen in your app.

class MyPage extends BaseStatefulWidget {
  const OtpVerificationPageMobile({super.key});

  @override
  BaseState<MyPage> createState() =>
      _MyPageState();
}

class _MyPageState
    extends BaseState<OtpVerificationPageMobile> {
  ....
  @override
  void initState() {
  super.initState();
  ....
  }
  @override
  Widget setBody(BuildContext context) {
  return Container();
  }

  @override
  String? setScaffoldBackgroundImage() {
  return "";
  }

  @override
  Widget? setBottomNavigationBar() {
  return Container();
  }

  @override
  Future<bool> setOnWillPop() {
  return Future.value(true);
  }

  @override
  bool setResizeToAvoidBottomInset() {
  return false;
  }
}

as another example widget app_fundamental provide NavBarWidget and NavBarBloc to easy use NavBar in our app all you need to do is to use NavBarWidget in you StateFullWidget as BottomNavigationBar like this.

@override
Widget? setBottomNavigationBar() {
  return NavBarWidget(
      height: 64.0,
      textFontSize: 14.0,
      background: Colors.white,
      borderColor: Colors.black,
      selectedColor: Colors.blue,
      unSelectedColor: Colors.white,
      selectedFontWeight: FontWeight.w700,
      unSelectedFontWeight: FontWeight.w900,
      ....
  );
}

also you should identify your naveBarItemList by using navBarBloc like this.

navBarBloc.naveBarItemList = [
NavBarItem(
title:"Home",
widget: Container(),
selectedIcon: SvgPicture.asset(
selectedHomeSvg,
width: 24.0,
height: 24.0,
),
unSelectedIcon: SvgPicture.asset(
'assets/svg/home.svg',
width: 24.0,
height: 24.0,
),
onTap: () {
debugPrint('index 0');
},
),
NavBarItem(
.....
),
NavBarItem(
.....
),
];

AppButton
(
title: 'Back',
alignment: AppButtonAlign.start,
icon: SvgPicture.asset('assets/svg/backButtonIcon.svg'),
onTap: () => Navigator.pop(context)
);

AppText
(
label: 'Text',
textAlign: TextAlign.right,
style: TextStyle(
color: Colors.red,
fontSize: 14,
fontWeight: FontWeight.bold,
)
);

AppTextFormFieldItem
(
controller: TextEditingController(),
readOnly:
stateSnapshot.data?.status == RequestStatus.loading
? true
    : false,
autofocus: true,
title: AppLocalizations.of(context).email,
formFieldItemType: AppFormFieldItemType.email,
stream: _signInBloc.emailStream,
onChanged: _signInBloc.onChangedEmailField,
textInputType: TextInputType.emailAddress,
labelFontColor: Colors.black,
borderColor: Colors.grey,
focusedBorderColor: Colors.grey,
iconColor: Colors.black,
focusedIconColor: Colors.grey,
fillColor: Colors.white,
showHint: true,
validator: (val) => _signInBloc.validateEmail(val),
fontSize: 14.0,
contentPadding: EdgeInsets.symmetric(
horizontal: 8.0,
vertical: 8.0),
borderRadius: BorderRadius.all(
Radius.circular(8.0
)
)
);

AppBorderedDropDown(
            list: ["first", "second", "third"],
            selectedStateSubject: selectedStateSubject,
            selectedSubject: selectedSubject,
            borderColorSubject: borderColorSubject,
            onTap: (){},
            onChange: (val){},
            titleKey: "",
            label: "",
            hint: "",);

AppBottomSheet(context: context, widget: Container(),);

AppContainerWithLabel(label: Text("label"), child: widget,);

final AppDialog appDialog = AppDialog();
appDialog.child = AppDialogContent(title: "title",description: "description",);

...

Future<void> showAppDialog(AppDialog appDialog) async {
  await showDialog(
      context: context,
      barrierDismissible: false,
      builder: (BuildContext context) => appDialog);
}

Future<void>? hideAppDialog(AppDialog appDialog) {
  if (appDialog.isShowing()) {
    appDialog.pop();
    appDialog = AppDialog();
  }
  return null;
}

AppDivider(
          dividerPadding: EdgeInsets.symmetric(horizontal: 16.0),
          thickness: 2.0,
          dividerColor: Colors.grey,
        );

AppExpandedRadioButton(
          onTap: () {},
          label: "label",
          labelFontSize: 24.0,
          labelFontColor: Colors.black,
          isSelected: true,
        );

AppImage(
          path: "image_path",
          height: 40.0,
          width: 40.0,
          isCircular: true,
          boxFit: BoxFit.cover,
          color: Colors.white,
          onPressed: () {},
          defaultImage: AppImage(path: "default_image_path"),
          loadingWidget: LoadingWidget(),
        );

AppLabelWithIcon(
          label: "label",
          labelColor: Colors.black,
          icon: Icon(Icons.search),
        );

AppRefreshIndicator(
            child: Container(),
             onRefresh: () {},
             );

AppWebView(
        title: "title",
         url: "",
         );

final Encryptor encryptor = Encryptor();
      encryptor.encryptData("hello");
      encryptor.decryptData("efgdt-vvxvxxvxvxfgfg-bcbcbcbcbcbcbcbcbcbcb");
