Kartal is the place for my borning country so I created an extension for giving born to more power with simple use. If you want to example with these extensions, you should be look example folder.


Future Extension

You can easy use for network or any future request.

  Future<String> fetchDummyData(BuildContext context) async {
    await Future.delayed(context.durationLow);
    return Future.value('Okey');
  }

  @override
  Widget build(BuildContext context) {
    return fetchDummyData(context).toBuild<String>(
        onSuccess: (data) {
          return Text(data);
        },
        loaindgWidget: CircularProgressIndicator(),
        notFoundWidget: Text('Oh no'),
        onError: FlutterLogo());
  }

Context Extension


You can easy to use context power so context help for many needs.

General Context Extension

I use the most this extesnion. It's most needed for the your products.

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(brightness: context.appBrightness),
      body: Container(
        height: context.mediaQuery.size.height,
        color: context.colorScheme.onBackground,
        child: Text(context.isKeyBoardOpen ? 'Open' : 'Close', style: context.textTheme.subtitle1),
      ),
    );
  }

Widget Extension

Sometimes need visible widget so you can this extension.

Text("Hello").toVisible(isAvaible);

MediaQuery Extension

These extension gives device size use so you can need dynamic(grid) value for device aspect, use the dyanmic height or width.

  SizedBox(
      height: context.dynamicHeight(0.1),
      width: context.dynamicWidth(0.1),
      child: Text('${context.lowValue}'),
    );
  }

These directly access navigation features.

   Column(
        children: [
          FloatingActionButton(
            child: Text('Navigation Prop'),
            onPressed: () {
              context.navigation.canPop();
            },
          ),
          FloatingActionButton(
            onPressed: () {
              context.pop();
            },
            child: Text('Navigation Pop'),
          ),
          FloatingActionButton(
            onPressed: () {
              context.navigateName('/hello');
            },
            child: Text('Navigation Named'),
          ),
          FloatingActionButton(
            onPressed: () {
              context.navigateToReset('/hello');
            },
            child: Text('Navigation Named and Remove'),
          ),
        ],
      )

Duration Extension

These extensions mainly for animation use.

AnimatedOpacity(
      opacity: context.isKeyBoardOpen ? 1 : 0,
      duration: context.durationLow,
      child: Text('${context.durationLow.inHours}'),
    );

Padding Extension

These extensions declare project main padding values.

Padding(
      padding: context.paddingLow,
      child: Padding(
        padding: context.horizontalPaddingMedium,
        child: Text('${context.durationLow.inHours}'),
      ),
    )

Empty Widget Extension

Sometimes need empty widget screen for space area, you can use that time.

Column(
      children: [
        Text('${context.durationLow.inHours}'),
        context.emptySizedHeightBoxHigh,
        Row(
          children: [Text('Row'), context.emptySizedWidthBoxLow, Text('Row')],
        )
      ],
    )

Radius Extension

This extension only uses to draw the border.

  Container(
      decoration: BoxDecoration(borderRadius: context.lowBorderRadius),
    );

Image Extension 🌠


You can use very easy rotiaton from image.

  @override
  Widget build(BuildContext context) {
    return Image.network('https://picsum.photos/200/300').bottomRotation;
  }

Intager Extensıon


Now, we has a a little code.

extension IntagerExtension on int {
  int get randomValue => Random().nextInt(17);
}

List Extension

We need list operation sometmes null check etc.

List Validation Extension

We can check this for empty and null.

  final List values = null;
  @override
  Widget build(BuildContext context) {
    return Container(
      child: values.isNotNullOrEmpty ? Text('ok') : Text('false'),
    );
  }

String Extension


String need validation, color, launch, share etc.

Package Information Extension

You can access directly applicaton platform information.

 Text(''.appName)
 Text(''.version)
 Text(''.packageName)
 Text(''.buildNumber)

Validation Extension

Validate your string value to some features.

 TextFormField(validator: (value) => value.isNotNullOrNoEmpty ? null : 'fail'),

Input Formatter

You need the value mask and validation use formatter extension.

Column(
      children: [
        TextFormField(validator: (value) => value.isNotNullOrNoEmpty ? null : 'fail'),
        TextFormField(validator: (value) => value.isValidEmail ? null : 'fail'),
        TextField(
          inputFormatters: [InputFormatter.instance.phoneFormatter],
          onChanged: (value) {
            print('${value.phoneFormatValue}');
          },
        )
      ],
    );

Launch Any Content In App Dialog Extension

You need open the value in device system. You can just say string value to launch prefix.

 void openEmail(String value){
    value.launchWebsite;
 }

These extension share your value to other apps or optional apps.


  void shareWhatssApp(String value) {
    value.shareWhatsApp();
  }

  void openWeb(String value) {
    value.launchWebsite;
  }

Authorization Extension

Sometimes need this extension from send service request so easy create bearer token string.

  void bearerTokenHeader() {
    print('TOKEN-X-X-X'.beraer);
  }
