vuzix_flutter_plugin 是一个用于在 Flutter 应用中与 Vuzix 设备进行交互的插件。通过这个插件，开发者可以访问 Vuzix 设备的硬件功能，如按钮事件、显示控制等。
以下是如何使用 vuzix_flutter_plugin 的基本步骤：
1. 添加依赖
首先，在你的 pubspec.yaml 文件中添加 vuzix_flutter_plugin 依赖：
dependencies:
flutter:
sdk: flutter
vuzix_flutter_plugin: ^版本号
请确保使用最新的版本号，你可以在 pub.dev 上查找最新的版本。
2. 导入插件
在你的 Dart 文件中导入插件：
import 'package:vuzix_flutter_plugin/vuzix_flutter_plugin.dart';
3. 初始化插件
在使用插件之前，确保初始化它：
void main() {
VuzixFlutterPlugin.initialize();
runApp(MyApp());
}
4. 监听按钮事件
你可以通过插件监听 Vuzix 设备上的按钮事件。例如，监听按下和释放事件：
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _buttonStatus = 'No button pressed';
@override
void initState() {
super.initState();
VuzixFlutterPlugin.onButtonPressed.listen((event) {
setState(() {
_buttonStatus = 'Button pressed: $event';
});
});
VuzixFlutterPlugin.onButtonReleased.listen((event) {
setState(() {
_buttonStatus = 'Button released: $event';
});
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Vuzix Button Example'),
),
body: Center(
child: Text(_buttonStatus),
),
),
);
}
}
5. 控制显示
你还可以使用插件来控制 Vuzix 设备的显示。例如，设置显示亮度：
void setBrightness(int brightness) async {
await VuzixFlutterPlugin.setBrightness(brightness);
}
