Getting Started

This project is a starting point for a Flutter plug-in package, a specialized package that includes platform-specific implementation code for Android and/or iOS.

This library works to provide the tools and parts needed to build your project faster.

As of now this package supports only Android

In this library you can find:

  • SharedPreferences.
  • AppTheme Dark-light.
  • AutoSizeText.
  • ContextExtensions.
  • ErrorHandler.
  • IntExtensions.
  • TextStyle.
  • StringExtension.
  • Spacing.
  • WidgetExtension.
  • Button (Type) => rounded - small - medium - text - block - outlined - large.
  • Container (Type) => none - bordered - roundBordered - rounded.
  • TextFormField (Type) => none - bordered - roundBordered - rounded.
  • Text => There are mainly 13 types of Text widgets.
  • Patterns for url - phone - image - audio - text - document - excel - ppt - apk - pdf - html.

1- How to use the SharedPreferences

set String

 await MySharedPreferences.setString('username', ' Enter Username');

get String

 await MySharedPreferences.getString('username', ' Enter Username');

get delete


await MySharedPreferences.deleteString('username');

You can also do a lot of operations with SharedPreferences

2- Use the AppTheme

import 'package:provider/provider.dart';
import 'package:flutter/material.dart';
import 'package:flutter_utils_project/flutter_utils_project.dart';
Future<void> main() async {
runApp(
  MultiProvider(
      providers: [
     ChangeNotifierProvider<FuAppThemeNotifier>( 
     create: (_) => FuAppThemeNotifier(),), ],
     child: const MyApp()
 ) );
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Consumer<FuAppThemeNotifier>(
        builder: (BuildContext context, FuAppThemeNotifier value, Widget? child) {
      return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: "Flutter Utils Project",
      theme: FuAppTheme.getThemeFromThemeMode(),
      home: const HomeScreen()//navigator to your HomeScreen
      );
    });
  }
}

3- Use AutoSizeText

AutoSizeText behaves exactly like a Text. The only difference is that it resizes text to fit within its bounds.

AutoSizeText(
  'A really long String',
  style: TextStyle(fontSize: 30),
  maxLines: 2,
)

maxLines

The maxLines parameter works like you are used to with the Text widget. If there is no maxLines parameter specified, the AutoSizeText only fits the text according to the available width and height.


AutoSizeText(
  'A really long String',
  style: TextStyle(fontSize: 30),
  maxLines: 2,
)

4- Use the ContextExtensions

bool get isSmallTablet => (mediaQueryShortestSide >= 600); can you get found context Extensions `mediaQueryPadding` - `mediaQuery` - `textTheme` - `mediaQueryViewPadding` - `orientation` - `textScaleFactor` - `mediaQueryShortestSide` and Responsive ui `isPhone` - `isSmallTablet` - `isLargeTablet` - `isTablet` and the a lot Extensions

 Container(
  color: context.textTheme.bodyText2!.color,//can yuo get found Context Extensions theme
  height: context.height / 2,//can yuo get found Context Extensions height (mediaQuerySize height)
  width: context.width / 1.5,
  child: const Center( child: Text( 'wellCome', style: TextStyle(color: Colors.white), ),
  ),
),

5- ErrorHandler

can you handler error Exception. Handling for Error Exception Example (No Internet Connection 😑 or Bad response format 👎 or Couldn't find the post 😱 ) And if nothing happens, he'll return the default mistake.


 Future<List<YOURMODEL>?> getProfile(BuildContext context) async {
    try {
       static const Map<String, String> HEADER = {
    "Content-type": "application/json",
      "Accept": "application/json" "Access-Control-Allow-Origin: *",
      HttpHeaders.authorizationHeader: 'YOUR TOKEN'
  };
      List<YOURMODEL> profile = [];//your model class
      http.Response response = await http.get(
        Uri.parse('YOUR URI'),
        headers: HEADER
      );
      if (response.statusCode == 200) {
        List list = json.decode(response.body);
        profile = list.map((model) => YOURMODEL.fromJson(model)).toList();
        return profile;
      } else {
        var massages = jsonDecode(response.body);
        String error = massages['Error'];
       // return showSnackBar(); //can you return anything
       print(error)
      }
    } catch (err) {
     /*
        Handling for Error Exception Example  (No Internet Connection 😑
       or Bad response format 👎
       or Couldn't find the post 😱 )
       And if nothing happens, he'll return the default mistake.
       */
      ApiErrorHandler.parseError(err, context,);
      print("$err Error");
    }
    return null;
  }

6- IntExtensions

height => Leaves given height of space


Container(child:Text('Example1')),
5.height,
Container(child:Text('Example2')),

width => Leaves given width of space

isSuccessful =>HTTP status code

if(response.statusCode=isSuccessful){
  print(' statusCode Successful')
}

7- TextStyle

FuTextStyle - gives 13 different type of styles to the text on the basis of size


 FuText.h1(
'Example h1',
color: Colors.white,
),

 FuText.b1(
'Example b1',

  child: const Text('getNumericOnly'))

removeAllWhiteSpace

Removes white space from given String

ElevatedButton(
onPressed: () {
  String text = 'image.    png12';
  print(text.removeAllWhiteSpace());

  ElevatedButton(
  onPressed: () {
    String email = 'testemail@gmail.com';
    print(email.validateEmail());

  },
  child: const Text('validateEmail'))

Returns true if given String is null or isEmpty

isEmptyOrNull

Check email validation

  ElevatedButton(
  onPressed: () {
 String data = '';
 if(data.isEmptyOrNull){
 print(data.isEmptyOrNull);
  }else{ print('false');}},
  child: const Text('isEmptyOrNull'))

capitalizeFirstLetter

Capitalize given String

ElevatedButton(
onPressed: () {
  String data = 'welcome';
  print(data.capitalizeFirstLetter());
},
child: const Text('capitalizeFirstLetter'))

and find a lot String extension

9- Spacing

FuSpacing - provides spacing of various types.

const Text('welcome'),
FuSpacing.height(30),
const Text('FuSpacing')

  Text('withHeight').withHeight(20),
  Text('widthAndHeight').widthAndHeight(height: 12, width: 11),
  Text('visible').visible(false),
  Text('onTap').onTap(() { print('print'); }),
  Text('withTooltip').withTooltip(msg: 'Text'),
  Text('paddingAll').paddingAll(12),
  Text('paddingBottom').paddingBottom(12),
  Text('paddingLeft').paddingLeft(12),
  Text('paddingRight').paddingRight(12),
  Text('paddingOnly').paddingOnly(bottom: 30,top: 50,left: 0,right: 12),
