flutter pub add screentasia基于插件公开信息、社区数据与项目使用情况整理的选型参考。
Screentasia 是一个 Flutter 包，旨在简化在所有屏幕尺寸和平台上的响应式、自适应 UI 的创建。它提供了可扩展布局、动态排版和一致间距的工具，确保设计在 Android、iOS、Web、macOS、Windows 和 Linux 上均呈现精美效果。内置工具可处理不同的屏幕密度和方向，减少样板代码，简化响应式开发。非常适合需要像素级适应性且不牺牲可维护性的应用。

✨ Give a star for the Repo ✨A Flutter package that helps you create beautifully adaptive designs for all screens with a wealth of features.
Please check the latest version before installation.
If there is any problem with the new version, please use the previous version
dependencies:
flutter:
sdk: flutter
# add screentasia
screentasia: ^{latest version}
import 'package:screentasia/screentasia.dart';
| Property | Type | Default Value | Description |
|---|---|---|---|
| adaptiveFrom | double | adaptiveFrom . mobile | Used to adapt sizes from chosen screen ex: if 500 width on a desktop is equal to 50% of the screen width, will be equal to 50% to all screens,also you can use custom screen with customScreen method |
| adaptivePercentage | AdaptivePercentage | AdaptivePercentage(mobile: 100, tablet: 100, desktop: 100) | For adaptive percentage in different screens, also can disable adaptive for specific screens with 0 value as parameter |
| builder | Function | null | Return widget that uses the library in a property (ex: MaterialApp's theme) |
| child | Widget | null | A part of the builder that its dependencies/properties don't use the library |
| rebuildFactor | Function | default | Returns whether to rebuild or not when screen metrics change. |
Note : You must either provide builder, child or both.
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return ScreentasiaInit(
adaptiveFrom: AdaptiveFrom.mobile, //optional for custom screen ex: customScreen(400,700)
adaptivePercentage: AdaptivePercentage(mobile:100,tablet:100,desktop:100),//optional
builder: (context , child) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Example',
home: child,
);
},
child: const HomePage(title: 'Example'),
);
}
}
We can create adaptive value for (width,height,font,etc) based on value in specific device for example (Mobile,Tablet,Desktop) or specific device dimension ( width,height )
to apply adaptive value for all screen
ex: 250.w '250 width in mobile screen'
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return ScreentasiaInit(
adaptiveFrom: AdaptiveFrom.mobile,
adaptivePercentage:
const AdaptivePercentage(mobile: 100, desktop: 100, tablet: 100),
builder: (context, child) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Flutter screentasia',
home: Scaffold(
appBar: AppBar(
title: const Text('Flutter screentasia Demo Page'),
),
body: Container(
color: Colors.blue,
width: 250.w,
)));
},
);
}
}
We can create adaptive value for (width,height, font,etc) based on percentage
for example we will use width percentage 'wb' in diffrent screen sizes
ex: 50wp '50 width percent in screen'
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return ScreentasiaInit(
adaptiveFrom: AdaptiveFrom.mobile,
adaptivePercentage:
const AdaptivePercentage(mobile: 100, desktop: 100, tablet: 100),
builder: (context, child) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Flutter screentasia',
home: Scaffold(
appBar: AppBar(
title: const Text('Flutter screentasia Demo Page'),
),
body: Container(
color: Colors.blue,
width: 50.wp,
)));
},
);
}
}
We can create adaptive value for (width, height, font, etc) based on percentage
for example, we will use width percentage 'wb' in different screen sizes with different value percentages in specific screens
ex: 100wp '100 width per cent from Desktop Screen'
50wp '50 width per cent from Tablet Screen'
25wp '25 width per cent from Mobile Screen'
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return ScreentasiaInit(
adaptiveFrom: AdaptiveFrom.mobile,
adaptivePercentage:
const AdaptivePercentage(mobile: 100, desktop: 100, tablet: 100),
builder: (context, child) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'Flutter screentasia',
home: Scaffold(
appBar: AppBar(
title: const Text('Flutter screentasia Demo Page'),
),
body: Container(
color: Colors.blue,
width: 100.wp.ap(
adaptivePercentage: const AdaptivePercentage(
desktop: 100, tablet: 50, mobile: 25)))));
},
);
}
}
Screentasia().setWidth(540) (dart sdk>=2.6 ) another way (540.w) //Adapted to screen width
Screentasia().setHeight(200) (dart sdk>=2.6 ) another way (200.h) //Adapted to screen height, under normal circumstances, the height still uses x.w
Screentasia().radius(200) (dart sdk>=2.6 ) another way (200.r) //Adapt according to the smaller of width or height
Screentasia().setSp(24) (dart sdk>=2.6 ) another way (24.sp) //Adapter font
Screentasia().setPercentage(MediaQuery.sizeOf(context).width,50) (dart sdk>=2.6 : 50.wp) //Device width in Percentage, You can use Height just replace MediaQuery.sizeOf(context).width with MediaQuery.sizeOf(context).height
EdgeInsets.all(10).w //EdgeInsets.all(10.w)
EdgeInsets.only(left:8,right:8).r // EdgeInsets.only(left:8.r,right:8.r).
Radius.circular(16).w //Radius.circular(16.w)
BorderRadius.all(Radius.circular(16)).w
ap(tablet:50) //adaptive percentage, tablet 50 means that adaptive percentage 50% only on tablet screens, the default is 100% for all screens
