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 mostly use this extension. It's most needed for 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 you need visible widget so you can this extension.

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

MediaQuery Extension

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

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

This extension can directly access the 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.navigateToPage(HomeViewDetail(), type: SlideType.TOP);
            },
            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 declares the projects main padding values.

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

Empty Widget Extension

Sometimes you 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),
    );

Device Screen Size Extension

This extension can be used to create responsive widgets.

  Scaffold(
      drawer: context.isSmallScreen ? Drawer() : null,
      body: Container(),
    );

Device Operatig System Extension

This extension can be used to create native widgets.

  SizedBox(
      child: context.isIOSDevice ? CupertinoButton() : MaterialButton(),
    );

Image Extension 🌠

You can use very easy rotation from image.

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

Integer Extension

Now, we have a little code.

10.randomValue

Key Extension

Find a render object with using key

   final GlobalKey key = GlobalKey();
   final GlobalObjectKey key2 = GlobalObjectKey('vb');


  @override
  Widget build(BuildContext context) {
    return Container(
      key:key,
      child:Text('hello',key:key2)
    );
  }
  void findElementAndDetail(){
    final box = key.renderBox;
    final boxHeight = key.height
  }

    void scrollToObjectKey(){
      key2.scrollToWidget()
  }

List Extension

You can find a specific index or null value for the list

   final List<User>? values;
  void searchIndex(){
    values.indexOrNull
  }

List Validation Extension

We can check this for empty and null.

   final List<T>? values = null;
  @override
  Widget build(BuildContext context) {
    return Container(
      child: values.isNotNullOrEmpty ? Text('ok') : Text('false'),
    );
  }

String Extension

String needs validation, color, launch, share etc.

Package Information Extension

You can access directly application 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'),
        TextFormField(validator: (value) => value.isValidPassword ? null : 'fail'),

        TextField(
          inputFormatters: [InputFormatter.instance.phoneFormatter],
          onChanged: (value) {
            print('${value.phoneFormatValue}');
          },
        )

  Container(
    child: file.isImageFile ? Image.asset('${file.path}') : SizedBox();
  );
