first #

Future<void> main() async {
//You will need to initialize AppThemeNotifier class for theme changes.
WidgetsFlutterBinding.ensureInitialized();
FlutterUtilsProject.init();}

Examples #

1 -SnapHelperWidget

SnapHelperWidget makes easy implementation for future or stream builder

 SnapHelperWidget<List<YOURMODEL>>(

  future: getData(context),
  defaultErrorMessage: 'default Error Message',
  errorWidget: const Text('error Widget').center(),
  loadingWidget: const CircularProgressIndicator().center(),
  ///useConnectionStateForLoader: ,
  ///initialData: ,this is initial Data
  onSuccess: (List<YOURMODEL> snap) {
  return ListView.builder(
  itemCount: snap.length,
  physics: const BouncingScrollPhysics(
  parent: AlwaysScrollableScrollPhysics()),
  itemBuilder: (BuildContext context, int index) {
  var data = snap[index];

  return Text(data.name);

  },
  );
  }),

2- FuLog #


Future<void> main() async {
//You will need to initialize AppThemeNotifier class for theme changes.
WidgetsFlutterBinding.ensureInitialized();
FlutterUtilsProject.init();
///if you want enable log console, do it.
FlutterUtilsProject.enableLog();
///If you don't want to show the log consol, do it.
FlutterUtilsProject.disableLog();
/// default log consol equal enable
}

3- 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
      );
    });
  }
}

4- Use AutoSizeText #

group You can synchronize the font size of multiple AutoSizeText. They will fit their boundaries and all AutoSizeText in the same group have the same size. That means they adjust their font size to the group member with the smallest effective font size.

Note: If a AutoSizeText cannot adjust because of constraints like minFontSize, it won't have the same size as the other group members.

An instance of AutoSizeGroup represents one group. Pass this instance to all AutoSizeText you want to add to that group. You don't have to care about disposing the group if it is no longer needed.

Important: Please don't pass a new instance of AutoSizeGroup every build. In other words, save the AutoSizeGroup instance in a StatefulWidget.

var myGroup = AutoSizeGroup();

AutoSizeText(
  'Text 1',
  group: myGroup,
);

AutoSizeText(
  'Text 2',
  group: myGroup,
);



Demo

stepGranularity The AutoSizeText will try each font size, starting with TextStyle.fontSize until the text fits within its bounds. stepGranularity specifies how much the font size is decreased each step. Usually, this value should not be below 1 for best performance.

AutoSizeText(
  'A really long String',
  style: TextStyle(fontSize: 40),
  minFontSize: 10,
  stepGranularity: 10,
  maxLines: 4,
  overflow: TextOverflow.ellipsis,
)



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,
)

5- Context Extensions #

Are you still typing MediaQuery.of(context).size... or Navigator.of(this).push.. ? Let's change that 🤩

❌ Navigator.of(context).push(MaterialPageRoute(
    builder: (_) => HomeScreen(),
  ));

✅ context.push(HomeScreen());

❌  MediaQuery.of(context).size.width;

✅ context.width;
✅ context.height;

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), ),
  ),
),

6- Error Handler #

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 {
  List<YOURMODEL> profile = [];//your model class
  http.Response response = await http.get(
  Uri.parse('YOUR URI'),
  headers: YourHeader()
  );
  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;
  }


7- Int Extensions #

height => Leaves given height of space #


Container(child:Text('Example1')),
❌SizedBox(height:12),
or
❌SizedBox(width:12),
Container(child:Text('Example2')),

✅ 12.height,
✅ 12.width,
Container(child:Text('Example2')),

width => Leaves given width of space #

Row(children:[
Text('width1'),
5.width,
Text('width2'),
])
