About Rixa #

Rixa is the easiest and simplest way to design your application.
Creating the application skeleton could be tough and time taking. It can cause unnecessary time waste and struggle. After completing the simple steps below, you can use this skeleton we've prepared for yo. Work on a single project to create your multi-platform app instead of separating your project for any specific platform. We have also prepared a lot of widgets that will come handy to make your job easier.

Features #

Very simple page/route system to understand.
Writing the same textstyle again and again could become a boring task, you will have an access to your own textstyle. They can be customised for each page if you want
You will be able to access these features easily from anywhere in the application.

Page/Route management
Manage fonts of your pages
Text styles and Icon sizes adjusted(static/dynamic) according to screen sizes
Manage appearances&languages of your application(language and appearance information is held in cache memory. you do not need to make any special settings for this).
Adjustable custom settings
Language supported text and list of text
Run your own function on change of internet connection status
Also you can define spesific textstyle, icon size, word/sentence, color
Reach App size, width, height and the other variables anywhere on your project
All given features are customizable to your own liking(textstyles,iconsize,colors..)

Pre-defined TextStyle types(from small to big):

small1, small2, small3, small4, small5, small6, small7, small8, small9
medium1, medium2, medium3, medium4, medium5, medium6, medium7, medium8, medium9

Installing #

Add the library as a dependency to your project.

dependencies:
 rixa: ^latest

Then run flutter packages get

Basic Setup #

Run Rixa.setup() in main function.

void main() {
  Rixa.setup(
      pages: appPages, languages: languages, appearances: appearances);
}

To be able to display the changes on your page wrap your widgets with RixaBuilder

  @override
  Widget build(BuildContext context) {
    return RixaBuilder(builder: (properties, fonts) {
      return child;
    });
  }

That's it! You can fetch your defined fonts and rest of the rixa properties anywhere on your project!

Page Management #

Define your pages

  AppPages appPages = AppPages(
      pages: [
        RixaPage(
            name: "page1",
            fonts: PageFonts(text_small: 15),
            builder: (context, properties) => const Page1(),
            description: (properties) => "page1",
            route: "/page1"),
        RixaPage(
            name: "page2",
            fonts: PageFonts(text_small: 15),
            builder: (context, properties) => const Page2(),
            description: (properties) => "page2",
            route: "/page2"),
        RixaPage(
            name: "login",
            builder: (context, properties) => const LoginPage(),
            description: (properties) => "login",
            redirect: (properties) => isUserSignedIn?"/":null,
            route: "/login"),
        RixaPage(
          name: "home",
          route: "/",
        )
      ],
      initialRoute: "/",
    );

And put that inside setup function or set for PageState

  Rixa.setup(pages: appPages);

  Rixa.setAppPages(appPages);

Full view

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  Rixa.setup(
    pages: AppPages(
      pages: [
        RixaPage(
            name: "page1",
            fonts: PageFonts(text_small: 15),
            builder: (context, properties) => const Page1(),
            description: (properties) => "page1",
            route: "/page1"),
        RixaPage(
            name: "page2",
            fonts: PageFonts(text_small: 15),
            builder: (context, properties) => const Page2(),
            description: (properties) => "page2",
            route: "/page2"),
        RixaPage(
            name: "login",
            builder: (context, properties) => const LoginPage(),
            description: (properties) => "login",
            redirect: (properties) => isUserSignedIn?"/":null,
            route: "/login"),
        RixaPage(
          name: "home",
          route: "/",
        )
      ],
      initialRoute: "/login",
    ),
    languages: AppLanguages(
      languages: ["English", "Turkish"],
      initLanguge: "English",
    ),
    appearances: AppAppearances(
      appearances: [
        Appearance.dark(),
        Appearance.light(),
      ],
      initAppearance: Appearance.dark(),
    ),
  );

  runApp(const MyApp());
}

NestedPage #

If there is a common(stationary widgets) area used by a certain group of pages, you can make use of nestedPage

Architecture #

  AppPages appPages = AppPages(
      pages: [
        NestedPage(
            fonts: PageFonts(text_small: 10),
            builder: (context, properties, child) => MyNestedPage(child: child),
            children: [
              RixaPage(
                  name: "page1",
                  fonts: PageFonts(text_small: 15),
                  builder: (context, properties) => const Page1(),
                  description: (properties) => "page1",
                  route: "/page1"),
              RixaPage(
                  name: "page2",
                  fonts: PageFonts(text_small: 15),
                  builder: (context, properties) => const Page2(),
                  description: (properties) => "page2",
                  route: "/page2"),
              RixaPage(
                  name: "login",
                  builder: (context, properties) => const LoginPage(),
                  description: (properties) => "login",
                  redirect: (properties) => isUserSignedIn ? "/" : null,
                  route: "/login"),
              RixaPage(
                name: "home",
                route: "/",
              ),
            ])
      ],
      initialRoute: "/",
    );

MyNestedPage #

 class MyNestedPage extends StatefulWidget {
  final Widget child;
  const MyNestedPage({Key? key, required this.child}) : super(key: key);

  @override
  State<MyNestedPage> createState() => _MyNestedPageState();
}

class _MyNestedPageState extends State<MyNestedPage> {
  @override
  Widget build(BuildContext context) {
    return RixaBuilder(builder: (properties, fonts) {
      return Scaffold(
          backgroundColor: appColors.backgroundColor,
          appBar: const MyAppbar(),
          drawer: Rixa.properties.anyMobile ? MyDrawer() : null,
          body: Row(
            children: [
              if (!Rixa.properties.anyMobile)
                SizedBox(
                  height: double.infinity,
                  width: Rixa.properties.screenMode == ScreenMode.desktopLarge
                      ? 200
                      : 70,
                  child: LeftMenu(),
                ),
              Expanded(
                child: widget.child,
              ),
            ],
          ));
    });
  }
}

Change Page #

You have two ways to switch between pages

go #

-via BuildContext:

   context.go(route: route); //Provide the defined name of the target page

-via PageState:

   Rixa.pageManager.go(route: route,context:context); //Provide the defined name of the target page

goNamed #

-via BuildContext:

   context.goNamed(name: pageName); //Provide the defined name of the target page

-via PageState:

   Rixa.pageManager.go(name: pageName,context:context); //Provide the defined name of the target page

AppFonts #

By default fonts sizes are static unless your screen mode is ScreenMode.Mobile. To change this pre-defined setting, you can change the staticFonts parameter to true or false.

void main() {
  Rixa.setup(
      pages: appPages, languages: languages, appearances: appearances, staticFonts:true);
}

Pre-defined Fonts #

Pre-defined Text Styles #

small textstyles: small1, small2, small3, small4, small5, small6, small7, small8, small9 medium textstyles: medium1, medium2, medium3, medium4, medium5, medium6, medium7, medium8, medium9 large textstyles: large1, large2, large3, large4, large5, large6, large7, large8, large9 mega textstyles: mega1, mega2, mega3, mega4, mega5, mega6, mega7, mega8, mega9

xS()=>small3, S()=>small5, M()=>medium5, L()=>large5 xL()=>large7, mega()=>mega5, giga()=>mega7

Pre-defined Icon Sizes #

small icon sizes: icon_small1, icon_small2, icon_small3, icon_small4, icon_small5, icon_small6, icon_small7, icon_small8, icon_small9 medium icon sizes: icon_medium1, icon_medium2, icon_medium3, icon_medium4, icon_medium5, icon_medium6, icon_medium7, icon_medium8, icon_medium9 large icon sizes: icon_large1, icon_large2, icon_large3, icon_large4, icon_large5, icon_large6, icon_large7, icon_large8, icon_large9 mega icon sizes: icon_mega1, icon_mega2, icon_mega3, icon_mega4, icon_mega5, icon_mega6, icon_mega7, icon_mega8, icon_mega9

icon_xS()=>small3, icon_S()=>small5, icon_M()=>medium5, icon_L()=>large5 icon_xL()=>large7, icon_mega()=>mega5, icon_giga()=>mega7

TextStyle parameters = color, isBold, fontFamily, pageName, fontWeight, isStatic. These parameters have their own default values so you dont have to define them.

By default, Rixa supports Google Fonts. You can simply use them by calling font family name from parameter named fontFamily.

    Text(
      "Hello",
      style: Rixa.appFonts.large2(
      isBold: true,
      fontFamily:"Lato",
      pageName: "home",
      color: Rixa.appColors.textColor,
      fontWeight: FontWeight.normal),
        ),

Static and dynamic textstyle could be chosen for specific cases of your project

Fetching TextStyle

    Text(
       "Hello",
       style: Rixa.appFonts.large3(isStatic: true),
    )

Specify font sizes for the page #

You can change the font sizes specifically depended on pages. There are two ways to fetch these changes

Defining different font sizes in RixaPage

PageFonts(
       text_small: 15,
       text_medium: 30,
       text_large: 50,
       text_mega: 70
     )

Fetch these changes

via RixaBuilder

@override
Widget build(BuildContext context) {
  return RixaBuilder(
      name: "page1",
      builder: (properties, fonts) {
        return Text(
          "Rixa",
          style: fonts.medium3(),
        );
      });
}

via AppFonts

Text(
  "Rixa",
  style: Rixa.appFonts.medium3(pageName: "page1"),
)

Customizing Default Fonts #

If you are working with dynamic textstyle, these textstyle sizes are determined by the multiplication of pre-determined rates and total size of application

  Ratios : {
    "small": 0.013,
    "medium": 0.026,
    "large": 0.039,
    "mega": 0.052
  }
  IconRatios : {
    "small": 0.015,
    "medium": 0.03,
    "large": 0.045,
    "mega": 0.06
  }

These ratios could be changed with ratio parameter:

   Rixa.appFonts.changeStaticSizeRatio(name:"medium", ratio:0.022);

Default value of each static size are given below:

  Sizes : {
    "small": 20,
    "medium": 40,
    "large": 60,
    "mega": 80,
  }
  IconSizes : {
    "small": 30,
    "medium": 60,
    "large": 90,
    "mega": 120,
  }

These default values could be changed with code given below:

   Rixa.appFonts.changeStaticSize(name:"large", size:20);

AppColors #

AppColors contains the color types of your application. Application's appearances have to be defined to be able to use that.

Set Appearances #

-Define your appearances

  AppAppearances appearances = AppAppearances(appearances: [
    Appearance.dark(),
    Appearance.light(),
  ], initAppearance: Appearance.dark());

-And put that inside setup function or set your app's appearances through setAppAppearances function inside Rixa

  Rixa.setup(appearances: appearances);

  Rixa.setAppAppearances(appearances);

Variables of Appearance Class #

backgroundColor
textColor
hintColor
btnColor
btnTextColor
iconColor
secondaryBackgroundColor
secondaryTextColor
secondaryHintColor
secondaryBtnColor
secondaryBtnTextColor
secondaryIconColor
appBarBackgroundColor
appBarTextColor
appBarHintColor
appBarBtnColor
appBarBtnTextColor
appBarIconColor
drawerBackgroundColor
drawerTextColor
drawerHintColor
drawerBtnColor
drawerBtnTextColor
drawerIconColor
dialogBackgroundColor
dialogTextColor
dialogHintColor
dialogBtnColor
dialogBtnTextColor
dialogIconColor

Applications usually requires at least two background colors to fill the entire page. Some apps might have left menus and in such cases it would be wise to use secondary background color.

-An example below was given for app with left menus :

Row(
  children: [
    Expanded(
      child: Container(
        width: 400,
        height: double.infinity,
        color: Rixa.appColors.secondaryBackgroundColor,
        child: LeftMenu(),
      ),
    ),
    Expanded(
      child: Container(
        width: double.infinity,
        height: double.infinity,
        color: Rixa.appColors.backgroundColor,
        child: child,
      ),
    )
  ],
)

-This would mean two text colors are required to design the app. Those variables are called textColor and secondaryTextColor

AppSettings #

AppSettings is the control mechanism of your app. Whenever something gets updated in AppColors and AppFonts, this will trigger AppSettings. Which means AppColors and AppFonts dont need to be listened

AppSettings contains:

Languages
Device Type(Desktop-Mobile)
Internet connection status
Run your own function on change of internet connection status

Internet Connection Checker #

Run your own function on change of internet connection status:

  Rixa.appSettings.onConnectionChange=(status) {
    print("Connection status has changed");
  };

Languages #

Languages of the app need to be defined to be able to use "App Language" option.

  AppLanguages languages =
      AppLanguages(languages: ["English,Turkish"], initLanguge: "English");
  Rixa.setup(languages: languages);

RixaText #

Managing the multi language development can be done with ease with the utilization of smartText widget.

Make sure to define the languages of your app
RixaText can be used to create single string translations
RixaList can be used to create a list of translations for multiple strings

Warning: Parameters of RixaText&RixaList must be in same order with AppLanguages

RixaText can be used inside text widget #

Text(
  RixaText(["Page", "Sayfa"]).text,
  style: appFonts.giga(),
)

RixaList #

Text(
  RixaText(["Page", "Sayfa"]).text,
  style: appFonts.giga(),
)
for (var language in RixaList([
  ["Page1", "Page2", "Page3"],
  ["Seite1", "Seite2", "Seite3"]
]).texts)
  Text(language)

-A class that includes common words of an application can be designed the way it was shown in the example given below

class AppTexts {
  static String get ok => RixaText(["ok", "tamam"]).text;
  static String get hello => RixaText(["Hello", "Merhaba"]).text;
  static String get lang => RixaText(["Language", "Dil"]).text;
  static String get page => RixaText(["Page", "Sayfa"]).text;
  static String get login => RixaText(["Login", "Giriş"]).text;
  static String get appbar_title =>
      RixaText(["Rixa App Design", "Akıllı Uygulama Tasarımı"]).text;
  static String get settings => RixaText(["Settings", "Ayarlar"]).text;
  static String get signout => RixaText(["Signout", "Çıkış"]).text;
  static String get darkMode => RixaText(["Dark Mode", "Karanlık Mod"]).text;
  static String get btnText => RixaText([
        "You have pushed the button this many times",
        "Düğmeye bukadar çok bastın",
      ]).text;
  static List<String> get languages => RixaList([
        ["English", "Turkish"],
        ["İngilizce", "Türkçe"]
      ]).text;
  static List<String> get menus => RixaList([
        ["Page 1", "Page 2", "Settings", "Signout"],
        ["Sayfa 1", "Sayfa 2", "Ayarlar", "Çıkış"]
      ]).text;
}

-And it can be used as presented below:

Text(
  AppTexts.hello,
  style: appFonts.giga(),
)

Responsive Design #

If you want to make the design of your application responsive, you should make a special design for 2 to 4 modes. These modes are Mobile mode, Landscaped Mobile mode, Desktop Mini, Desktop Large. You may also want to make designs according to the screen sizes. That's what RixaProperties is for
