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'),
            ),
          ],
        ),
      ),
    );
  }
}
