Flutter设备翻转控制插件flutter_flip_devices的使用

这是一个用于开发支持翻转设备（如三星Galaxy Z Flip或三星Galaxy Z Flip 3）的Flutter应用程序的插件。它会在设备完全打开、半开和关闭时发出通知。对于非翻转设备，它始终会认为屏幕是完全打开的。

FlutterFlipListener

FlutterFlipListener 是一个Flutter小部件，当铰链状态发生变化时，会触发相应的回调函数。

FlutterFlipListener(
  onDeviceClosed: () {},
  onDeviceSemiOpened: () {},
  onDeviceFullyOpened: () {},
  child: YourWidget(),
);

FlutterFlipBuilder

FlutterFlipBuilder 是一个Flutter小部件，根据铰链的状态提供不同的子小部件。

FlutterFlipBuilder(
  onDeviceClosed: (BuildContext context) {
    return Text('Closed');
  },
  onDeviceSemiOpened: (BuildContext context) {
    return Text('Semi-opened');
  },
  onDeviceFullyOpened: (BuildContext context) {
    return Text('Fully opened');
  },
);

完整示例

以下是完整的示例代码，展示了如何在Flutter应用中使用 flutter_flip_devices 插件。

import 'package:flutter/material.dart';
import 'package:flutter_flip_devices/flutter_flip_devices.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Flip Devices for Flutter'),
        ),
        body: Column(
          children: const [
            Expanded(
              child: FlipListenerDemo(),
            ),
            Expanded(
              child: Center(
                child: FlipBuilderDemo(),
              ),
            ),
          ],
        ),
      ),
    );
  }

  // 显示Snack Bar的函数
  void showSnackBar(BuildContext context, String message) {
    ScaffoldMessenger.of(context).showSnackBar(
      SnackBar(
        content: Text(message),
      ),
    );
  }
}

// 使用FlutterFlipListener的小部件
class FlipListenerDemo extends StatelessWidget {
  const FlipListenerDemo({
    Key? key,
  }) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return FlutterFlipListener(
      onDeviceClosed: () {
        showSnackBar(context, 'Closed');
      },
      onDeviceSemiOpened: () {
        showSnackBar(context, 'Semi-opened');
      },
      onDeviceFullyOpened: () {
        showSnackBar(context, 'Fully opened');
      },
      child: Center(
        child: Text('Hello world !'),
      ),
    );
  }
}

// 使用FlutterFlipBuilder的小部件
class FlipBuilderDemo extends StatelessWidget {
  const FlipBuilderDemo({
    Key? key,
  }) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return FlutterFlipBuilder(
      onDeviceClosed: (BuildContext context) {
        return Text('Closed');
      },
      onDeviceSemiOpened: (BuildContext context) {
        return Text('Semi-opened');
      },
      onDeviceFullyOpened: (BuildContext context) {
        return Text('Fully opened');
      },
    );
  }
}
