BoxDecoration createBackground() {
return const BoxDecoration(
gradient: LinearGradient(

end: Alignment.bottomCenter,
colors: [
Color.fromARGB(255, 8, 25, 49),
Color.fromARGB(255, 11, 47, 98),
Color.fromARGB(255, 36, 69, 114),
Color.fromARGB(255, 31, 69, 123),
],
stops: [0.0, 0.4, 0.6, 1.0],
transform: GradientRotation(305 * math.pi / 180)));
}
}
BoundedPage 示例代码
class BoundedPage extends StatelessWidget {
const BoundedPage({super.key});
[@override](/user/override)
Widget build(BuildContext context) {
MobileWindowFeatures.setScreenProperties(
screenLimits: ScreenLimits.pageDrawLimitedByStatusBarNavigationBar,
statusBarColor: Colors.blue,
statusBarTheme: StatusBarThemeMWF.darkStatusBar,
navigationBarColor: Colors.white,
navigationBarTheme: NavigationBarThemeMWF.lightNavigationBar);
return Scaffold(
body: Stack(
children: [
Container(
decoration: createBackground(),
),
const Column(
children: [
Row(

begin: Alignment.topCenter,
end: Alignment.bottomCenter,
colors: [
Color.fromARGB(255, 134, 228, 27),
Color.fromARGB(255, 33, 228, 98),

mobile_window_features
是一个用于管理 Flutter 应用窗口特性的插件。它允许开发者在移动设备上控制窗口的各个方面,例如窗口的尺寸、方向、沉浸模式等。这个插件主要用于 Android 和 iOS 平台,帮助开发者更好地控制应用的外观和行为。
安装
首先,你需要在项目的 pubspec.yaml
文件中添加 mobile_window_features
插件的依赖:
dependencies:
flutter:
sdk: flutter
mobile_window_features: ^版本号
然后运行 flutter pub get
来安装插件。
使用方法
1. 设置窗口方向
你可以使用 MobileWindowFeatures
类来设置应用窗口的方向。例如,强制应用在竖屏或横屏模式下运行:
import 'package:mobile_window_features/mobile_window_features.dart';
void setPortraitOrientation() async {
await MobileWindowFeatures.setPreferredOrientations([DeviceOrientation.portraitUp]);
}
void setLandscapeOrientation() async {
await MobileWindowFeatures.setPreferredOrientations([DeviceOrientation.landscapeLeft, DeviceOrientation.landscapeRight]);
}
2. 设置沉浸模式
你可以使用 MobileWindowFeatures
来启用或禁用沉浸模式,隐藏或显示状态栏和导航栏:
void enableFullScreen() async {
await MobileWindowFeatures.setFullScreen(true);
}
void disableFullScreen() async {
await MobileWindowFeatures.setFullScreen(false);
}
3. 设置窗口大小
你可以使用 MobileWindowFeatures
来设置窗口的尺寸。这在 Android 平板或可调整大小的设备上非常有用:
void setWindowSize(double width, double height) async {
await MobileWindowFeatures.setWindowSize(width, height);
}
4. 获取窗口信息
你可以获取当前窗口的尺寸、方向等信息:
void getWindowInfo() async {
Size windowSize = await MobileWindowFeatures.getWindowSize();
Orientation orientation = await MobileWindowFeatures.getOrientation();
print('Window Size: $windowSize');
print('Orientation: $orientation');
}
注意事项
- 在 Android 上,某些功能可能需要特定的权限或配置。请确保在
AndroidManifest.xml
中正确配置了这些权限。 - 在 iOS 上,某些功能可能需要特定的设置或权限。确保在
Info.plist
中进行了相应的配置。
示例代码
以下是一个完整的示例,演示如何使用 mobile_window_features
插件来设置窗口方向和沉浸模式:
import 'package:flutter/material.dart';
import 'package:mobile_window_features/mobile_window_features.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
home: HomeScreen(),
);
}
}
class HomeScreen extends StatelessWidget {
[@override](/user/override)
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Window Features Example'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
ElevatedButton(
onPressed: () async {
await MobileWindowFeatures.setPreferredOrientations([DeviceOrientation.portraitUp]);
},
child: Text('Set Portrait Orientation'),
),
ElevatedButton(
onPressed: () async {
await MobileWindowFeatures.setPreferredOrientations([DeviceOrientation.landscapeLeft]);
},
child: Text('Set Landscape Orientation'),
),
ElevatedButton(
onPressed: () async {
await MobileWindowFeatures.setFullScreen(true);
},
child: Text('Enable Full Screen'),
),
ElevatedButton(
onPressed: () async {
await MobileWindowFeatures.setFullScreen(false);
},
child: Text('Disable Full Screen'),
),
],
),
),
);
}
}
