Tutorial : PageFastor #

Scroll Screen #

Get ride of RenderFlex overflowed by pixels.

Simple Example Create "PageFastor"

@override
Widget build(BuildContext context) {
return PageFastor(this,
content: getContent() );
}

Example For Content Long Data

  Widget getContent() {
    return Column( children: getLongDataForTestScroll() ,);
  }

  List<Widget> getLongDataForTestScroll() {
    List<Widget> data = [];
    for (int i = 1; i <= 70; i++) {
      var w = TextFastor(
        "Get ride of RenderFlex, data number $i",
        fontSize: 15,
        width: 300,
        color: Colors.yellow,
        margin: EdgeInsets.all(5),
      );
      data.add(w);
    }
    return data;
  }

Create any shape of Toolbar you want in Custom shape then put it at page template by using parameter "toolbar"

  @override
  Widget build(BuildContext context) {
    return PageFastor(this,
        toolbar: ToolbarSimpleFastor( context, "Page Shapes"),
        toolbar_height : 70,
        content: getContent() );
  }

The Default height of toolbar is 70
When the toolbar you draw different than 70 you can set height of toolbar by using "toolbar_height"

Background Feature #

Asset

set Image png to background, to make all content scrolling while the background image still hold at background

Asset with Opacity

  @override
  Widget build(BuildContext context) {
    return PageFastor(this,
        toolbar: ToolbarSimpleFastor( context, "Page Shapes"),
        toolbar_height : 70,

        //background
        assetBackground: const AssetImage("assets/images/background.png"),
        assetBackgroundOpacity: 0.3,

        content: getContent() );
  }

set Custom Widget hold at background, to make all content scrolling while the background widget still holding while scrolling

  @override
  Widget build(BuildContext context) {
    return PageFastor(this,
        toolbar: ToolbarSimpleFastor( context, "Page Shapes"),
        toolbar_height : 70,

        //background
         widgetBackground: CustomWidgetBackground(),
        
        content: getContent() );
  }

Navigation Bottom #

Custom Shape Navigation #

set Custom Widget hold at bottom of screen to navigate between multi screens

  @override
  Widget build(BuildContext context) {
    return PageFastor(this,

        //toolbar
        toolbar: ToolbarSimpleFastor( context, "Page Shapes"),
        toolbar_height : 70,

        //navigation bottom
        navigationBottom: NavigationFastor( context, 0),
        navigationBottom_height: 70,
        homeButtonsBackgroundColor: HexColor(  "#1593bc"),   //color background for home buttons

        content: getContent() );
  }

Change color #

Color of Home Buttons Android Device

By using parameter "homeButtonsBackgroundColor" you can write hexcode color

  @override
  Widget build(BuildContext context) {
    return PageFastor(this,
 
        homeButtonsBackgroundColor: HexColor(  "#1593bc"),   //color background for home buttons

        content: getContent() );
  }

Color of Status Bar

By using parameter "statusBarColorCustome" you can write hexcode color

  @override
  Widget build(BuildContext context) {
    return PageFastor(this,
 
        statusBarColorCustome: HexColor(  "#595629"),

        content: getContent() );
  }

Tutorial : Without Use Any State Management

use "setState()"
Create Variable at class

  var email_txt = "";
  var email_valid = AutovalidateMode.disabled;

Create Widget

    return TextFieldFastor(
        autovalidateMode: email_valid,
        margin: EdgeInsets.only( top: 10 ),
        padding: EdgeInsets.all( 5),
        background_color: Colors.white,
        validator: ValidatorTemplate.email( ),
        keyboardType: TextInputType.emailAddress,
        onChanged: (s){
          email_txt = s;
          Log.i( "tf_email() - change s: $s ");
        }
    );

Validate Form after click of button

          if(validateEmailAfterClick())  {
            ///TO-DO : After success success field
          }

  bool validateEmailAfterClick() {
    var result = true; //default good
    //email
    if ( ToolsValidation.isEmail( email_txt ) == false  ){
      Log.i( "missed email");
      result  = false;
      setState(() {
        email_valid = AutovalidateMode.always;
      });
    }
    return result;
  }

Tutorial : Use State Management Type "Cubit" like using "BLoc"

Using "Cubit" it similar as Using "BLoc"
Create Cubit


class AuthCubit extends Cubit<AuthState> {
  final LogInUseCase logInUseCase;

  AuthCubit( ) : super(AuthInitialState()) {}

  static AuthCubit get(context) => BlocProvider.of(context);

  AuthResponse authResponse = AuthResponse();

  Future login(String email_txt, String pass_txt) async {
    //....
  }
  
  void resetError() {
    emit( AuthInitialState() );
  }
 
}

Create Cubit State

abstract class AuthState {}

class AuthInitialState extends AuthState {}

class AuthLoadingState extends AuthState {}

class AuthSuccessState extends AuthState  { 
//.....
}

class AuthErrorState extends AuthState
{
 //.....
}

Declare Variable at class


  AuthState? stateCurrent;
  
  var emailValid = AutovalidateMode.disabled;
  var emailController = TextEditingController();

  var passValid = AutovalidateMode.disabled;
  var passController = TextEditingController();

This Way You Can Set Error Message To UI


  void setErrorToInputFields() {
    //email
    if (ToolsValidation.isEmail(emailController.text) == false) {
      Log.i("missed email");
      emailValid = AutovalidateMode.always;
    }
    //pass
    if (ToolsValidation.isPasswordValid(passController.text) == false) {
      Log.i("missed pass");
      passValid = AutovalidateMode.always;
    }
  }

Listener Cubit State

 
  Widget getContent() {
    return BlocConsumer<AuthCubit, AuthState>(
      listener: (context, state) {
        stateCurrent = state;

        if (state is AuthSuccessState) {
          RouterPage.home(context);
        }
      },
      builder: (context, state) {


        if (state is AuthErrorState) {
          setErrorToInputFields();
          printMessageError();
        }

        return  Column(children: [
              tfEmail(),
              tfPass(),
        ]);
    );
  }

Create Widget TextFieldFastor


  Widget tfEmail() {
    return TextFieldFastor(
        hint_text: "Email",
        controller: emailController,
        autovalidateMode: emailValid,
        margin: EdgeInsets.only(top: 10),
        padding: EdgeInsets.all(5),
        background_color: Colors.white,
        validator: ValidatorTemplate.email(),
        keyboardType: TextInputType.emailAddress,
        onChanged: (s) {
          // Log.i("tfEmail() - change s: $s ");

          bool isNotInit = stateCurrent! is AuthInitialState;
          if (isNotInit) {
            AuthCubit.get(context).resetError();
          }
        });
  }

  Widget tfPass() {
    return TextFieldFastor(
        hint_text: "Password",
        controller: passController,
        autovalidateMode: passValid,
        margin: EdgeInsets.only(top: 10),
        padding: EdgeInsets.all(5),
        background_color: Colors.white,
        validator: ValidatorTemplate.pass(),
        keyboardType: TextInputType.number,
        onChanged: (s) {
          // Log.i("tf_pass() - change s: $s ");
        });
  }

Class Utils For TextField #

class ValidatorTemplate : This have methods utils used at parameter "validator"

Class "TextFieldBackendErrorFastor" : #

This Class used for handle error from backend for every input fields.
Example error array backend response :

{
    "errors": {
        "email": [
            "The email provided is incorrect."
        ]
    }
}

Handle Error Array

We need in UI to handle every error array and to show to message error under every textfields
Example :

return TextFieldFastor(
        hint_text: "Email",
        controller: emailController,
        autovalidateMode: emailValid,
        validatorCustom: ValidatorTemplate.email(),
        errorBackendJson: errorState?.errors,
        errorBackendKeyJson:  "email",
        // errorBackendKeyJson2:  "role",
        margin: EdgeInsets.only(top: 10),
        padding:  EdgeInsets.all(5),
        background_color: Colors.white,
        keyboardType: TextInputType.emailAddress,
        onChanged: (s) {
        // Log.i("tfEmail() - change s: $s ");

        bool isNotInit = stateCurrent! is AuthInitialState;
        if (isNotInit) {
        AuthCubit.get(context).resetError();
        }
        });

Tutorial : CheckboxFastor #

Feature Fastor #

set color from constructor for active/inactive: color_inactive, color_active
Set Text Style : color, font size, weight.
Remove default padding found when use normal checkbox widget.

Get Start #

Simple Example

Create Variable at class

  bool isAgree = false;

Create Widget

    return CheckboxFastor( context: context, value: isAgree,
        margin: EdgeInsets.only(top: 10),
        text: "Are you agree to terms and condition.",
        text_color: Colors.brown,
        text_dimen: 20,
        color_inactive : Colors.brown,
        color_active: Colors.green,
        onChanged:  (updatedValue) {
          setState(() {
            isAgree = updatedValue!;
          });
        }
    );

SwitchFastor #

Feature Padding, Margin.
Feature send "TextStyle" in parameter constructor.
Feature Color action active and dis-active in parameter constructor.

Example Using with "Cubit" StateManagment #

ui :

  Widget _switchVipButton(){
    return SwitchFastor(defaultValue: cubit!.createReservation.isVip,
        onChange: (updateStatus){
      Log.i( "_switchVipButton() updateStatus: $updateStatus");
      cubit!.switchVipStatus(updateStatus);
    });
  }

Save the last updated status of change in variable

when calling

cubit!.createReservation.isVip

it just boolean varaible to carry data of switch status

  bool isVip = false;

create new state for class Cubit state

class ReservationCreateVipStatusChangeState extends ReservationState {}

call the change of switch value by calling "State Cubit"

  void switchVipStatus(bool updateStatus) {
    createReservation.isVip = updateStatus;

    emit(ReservationCreateVipStatusChangeState());
  }

ScrollFastor #

Example #



  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body:  createUI() 
    );
  }
 
  Widget createUI() {

    var scrollPage =  ScrollFastor(   child:  contentFormColumn() );

    var cont =  Container(
      padding: EdgeInsets.only(top: ToolbarCustom.heigh),
      margin:  EdgeInsets.only(   left: 16, right: 16, bottom: 16),
      child: scrollPage ,
    );
 
    return Stack(
      children: [
        cont,

        ToolbarCustom(pageContext: context, title:  "Add Reservation"),
 
      ],
    );
  }

  Widget contentFormColumn(){
    return Column(
      crossAxisAlignment: CrossAxisAlignment.start,
      mainAxisAlignment: MainAxisAlignment.start,
      children: [
 
        Text("input field 1"),
        Text("input field 2"),
        Text("input field 3"),
        Text("input field 4"),
        Text("input field 5"),
        Text("input field 6"),
        Text("input field 7"),
      ],
    );
  }

Helper Classes #

NetworkManager #

Feature #

Fix Error "XMLHttpRequest" found in platform Web.
Feature "CallBack()" return value like interface.
Feature NetworkType.file : to upload file in all platform( Android/IPhone/Web).
Class "NetworkHeaderTools" to generate "bearerToken()" and "basicAuth_usernameAndPassword()" easily.

Simple Example #

There is many steps to call API, you need to prepare: Body, Url, Header, token.
Here is guide

1- Generate Body

    Map<String, dynamic> bodyParameter = Map();
    bodyParameter[ "payment_method"] =  "cash";
    bodyParameter[ "price"] = "123";

2- Call Class "NetworkManagerDio.dart"

We will return the response in format JSON

      Response response = await NetworkManagerDio().post( url , body: bodyParameter   );
      if (response.statusCode == 200) {
        var result = CityResponse.fromJson( response.data);
          return result;
      }

NetworkConfigDio #

This class responsible for add "BaseUrl" to all EndPoint apis.

 var config =  NetworkConfigDio( baseUrl: "http://example.com");
 NetworkManagerDio( { config: config})

This Class responsible for add header in all apis like token

 var config =  NetworkConfigDio( 
                  baseUrl: "http://example.com",
                  headers : myHeader
                  );
 NetworkManagerDio( { config: config})

NetworkType #

NetworkManagerDio().get();
NetworkManagerDio().post();
NetworkManagerDio().put();
NetworkManagerDio().delete();
NetworkManagerDio().file();

Enum of Network type

enum NetworkTypeDio{
get,
post,
put,
delete,
file
}

Time Out

NetworkManagerDio().get( timeOutSecond: 50 );

Upload File

What is class "xFile" it's famous used by plugin "cross_file".
Generate XFile used by image picker

class "NetworkRequestFile"

this class used to set the path of file of "xFile" and set the key/value of file

Example upload file type "xFile"


  Future _startAPI() async  {
  
    //body request
    Map<String, dynamic> body = Map();
    body[ "payment_method"] =  "cash";
    body[ "price"] = "123";
    
    //set type requestFile
    NetworkRequestFile?  requestFile = NetworkRequestFile.fromXFileAndBody( xFile!, body );
 
    //header
    var token = await UserSingleTone.instance().getToken();
    Map<String, String> header = NetworkHeaderTools.bearerToken( token );

    NetworkManagerDio().file(urlApiLink,
        requestFile: requestFile,
        headers:  header,
        callback: (status, msg, json){

            parseJson(json );

        });

Types Of Webservice Network Dependence #

dio : use class "NetworkManagerDio.dart"
http : use class "NetworkManagerHttp.dart"

LangFastor #

Get Start Setup #

from main method call:

  await LangFastor.setupFromMainMethod();

from MyApp() class inside build() method write :

class MyApp  extends StatelessWidget {

 
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    LangFastor.setupFromBuildMethod(context);
      .....
    }
}

in yaml add path of assets

  assets:
    - assets/lang/

create new json file named "ar.json" in path : assets/lang/ar.json

      child:   Builder(
        builder: (BuildContext context) {
          return   MediaQuery(
            data: MediaQuery.of(context).copyWith(
              textScaleFactor: 1.0,
            ),
            child: blocConsumer(),
          );
        },
      ),
    );
  }

Method Handle Arabic/English #

Set/Get Arabic Value

How To Set Arabic or English

LangFastor.setArabic(context);
LangFastor.setEnglish(context);

How to check anywhere lang is arabic
this return boolean

LangFastor.isArabic

    DropdownFastor(
      textDirection: LangFastor.getTextDirection(),

Handle Stack Direction Left/Right Arabic #

      PositionFastor.directional(
        textDirection:  TextDirection.rtl,
        child:   Text(""),
        top: 0,
        start: 0  ,
      )

use "PositionedFastor.langFastor()" auto choose which langauge use used when use LangFastor plugin

      PositionedFastor.langFastor(
        child:   Text(""),
        top: 0,
        start: 0  ,
      )

Handle The Container Alignment Left/Right Arabic #

Fix Arabic Alignment of the "Container" by using "LangFastor.getAlignmentGeometry()"

Container(
    width: DeviceTools.getWidth(contextPage),
    alignment: LangFastor.getAlignmentGeometry(),// Alignment.topRight in arabic, while in english Alignment.topLeft
    child: menuFrameUI(),
);

Section: Arabic Translation #

There is Many Ways To Translate English text to Arabic Text :
1. First One Using json file to save english text as key while save arabic transalation as value
2. Second One Is Translate english to arabic In One Line.

First Way : Using Json File To Save Translation

write json with key/value for each english word

in path project : assets/lang/ar.json

{
  "Login" : "تسجيل الدخول"  , 
  "" : ""
}

In Widget Text or Button-Text

Use "english-world".trf()
where .trf() means translate by fastor, where used to translate any string Object

Text( "Login".trf()  )

Second Way : Write To Arabic In One Line

Use "ENGLISH-WORD".arf("ARABIC-WORD")
where arf() means arabic by fastor, where used to translate any string Object

Text(    "Login".arf("تسجيل دخول" )   )

How To Add In Network Header The Lang Value #

Add in "NetworkHeaderTools" the "LangFastor" new method "bearerTokenAndLang()" return header with "lang" = ar or en
the plugin code will do this step when used method "bearerTokenAndLang()" :

    header[ "Authorization"] =  "Bearer " + token;
    header[ "lang"] =  LangFastor.isArabic ? "ar" : "en";

Example Can Use This Method NetworkHeaderTools.bearerTokenAndLang()

    //header 
    Map<String, String> header = NetworkHeaderTools.bearerTokenAndLang( tokenFromCache );

    //webservice
    var responseDio = NetworkManagerDio().get(url, headers:  header );

Handle Direction ltr/rtl

    return   DropdownFastor(
        textDirection:  LangFastor.getTextDirection(),

SaveFastor #

Save In Cache By Using Plugin SharedPreference
Can Save Single Map() object
Can Save List of Map() Object
Setup

class MyApp extends StatelessWidget {
 
  @override
  Widget build(BuildContext context) {
     Fastor.initializeApp(context);     //init Fastor Plugin here
