Flutter隐私保护插件whisper_flutter的使用
Flutter隐私保护插件whisper_flutter的使用
安装库
首先，您需要在Flutter项目中添加whisper_flutter插件。可以通过以下命令安装：
flutter pub add whisper_flutter
导入库
在您的Dart文件中导入whisper_flutter库：
import 'package:whisper_flutter/whisper_flutter.dart';
编译 whisper.cpp 到共享库
无需手动编译 whisper.cpp，因为该过程会在您构建Flutter应用程序时自动完成。
快速开始
以下是快速启动示例代码，演示如何使用whisper_flutter进行语音转文字操作：
Whisper whisper = Whisper();
var res = await whisper.request(
whisperLib: "libwhisper.so",
whisperRequest: WhisperRequest.fromWavFile(
audio: File(audio),
model: File(model),
),
);
示例Demo
以下是一个完整的示例demo，展示了如何在Flutter应用中集成和使用whisper_flutter插件来实现语音转文字功能。

void main() {
WidgetsFlutterBinding.ensureInitialized();
runApp(
MaterialApp(

),
home: const MyHomePage(title: 'Flutter Demo Whisper Speech to Text'),
),
);
}
class MyHomePage extends StatefulWidget {
final String title;
const MyHomePage({
super.key,
required this.title,
});
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
String model = "";
String audio = "";
String result = "";
bool is_procces = false;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: SingleChildScrollView(
child: ConstrainedBox(
constraints: BoxConstraints(
minHeight: MediaQuery.of(context).size.height,
minWidth: MediaQuery.of(context).size.width,
),
child: Column(

if (file.existsSync()) {
setState(() {

});
}
}
},
child: const Text("Set Model"),
),
),
Padding(
padding: const EdgeInsets.all(10),
child: ElevatedButton(
onPressed: () async {
FilePickerResult? resul =
await FilePicker.platform.pickFiles();
if (resul != null) {
File file = File(resul.files.single.path!);
if (file.existsSync()) {
setState(() {

});
}
}
},
child: const Text("Set Audio"),
),
),
Padding(
padding: const EdgeInsets.all(10),
child: ElevatedButton(
onPressed: () async {
if (is_procces) {
return await CoolAlert.show(
context: context,
type: CoolAlertType.info,
text:
"Please wait until the previous process finishes.",
);
}
if (audio.isEmpty) {
await CoolAlert.show(
context: context,
type: CoolAlertType.info,
text:
"Audio is empty. Please set it first.",
);
if (kDebugMode) {
print("audio is empty");
}
return;
}
if (model.isEmpty) {
await CoolAlert.show(
context: context,
type: CoolAlertType.info,
text:
"Model is empty. Please set it first.");
if (kDebugMode) {
print("model is empty");
}
return;
}
Future(() async {
print("Started transcribe");
Whisper whisper = Whisper(
whisperLib: "libwhisper.so",
);
var res = await whisper.request(
whisperRequest: WhisperRequest.fromWavFile(
audio: File(audio),
model: File(model),
),
);
setState(() {
result = res.toString();
is_procces = false;
});
});
setState(() {
is_procces = true;
});
},
child: const Text("Start"),
),
),
],
),
replacement: const CircularProgressIndicator(),
),
Padding(
padding: const EdgeInsets.all(10),
child: Text("Model: ${model}"),
),
Padding(
padding: const EdgeInsets.all(10),
child: Text("Audio: ${audio}"),
),
Padding(
padding: const EdgeInsets.all(10),
child: Text("Result: ${result}"),
),
],
),
),
),
);
}
}
此示例包含了一个简单的UI界面，允许用户选择音频文件和模型文件，并通过点击“Start”按钮将音频文件转换为文本。结果会显示在界面上。

当然，以下是如何在Flutter项目中使用whisper_flutter插件来保护用户隐私的示例代码。whisper_flutter插件通常用于在应用中处理敏感信息，比如用户输入时隐藏或模糊化敏感数据。需要注意的是，具体的插件功能和使用方法可能会根据插件版本和Flutter SDK版本有所不同，因此请参考插件的官方文档进行确认。
1. 添加依赖
首先，在你的pubspec.yaml文件中添加whisper_flutter的依赖：
dependencies:
flutter:
sdk: flutter
whisper_flutter: ^最新版本号 # 请替换为最新版本号
然后运行flutter pub get来安装依赖。
2. 导入插件
在你需要使用隐私保护功能的Dart文件中导入插件：
import 'package:whisper_flutter/whisper_flutter.dart';
3. 使用Whisper进行隐私保护
假设你有一个TextField，你希望用户输入敏感信息时能够隐藏或模糊化这些输入。以下是如何使用whisper_flutter来实现这一点的示例代码：
import 'package:flutter/material.dart';
import 'package:whisper_flutter/whisper_flutter.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Whisper Example',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: Scaffold(
appBar: AppBar(
title: Text('Flutter Whisper Example'),
),
body: Center(
child: WhisperTextFieldExample(),
),
),
);
}
}
class WhisperTextFieldExample extends StatefulWidget {
@override
_WhisperTextFieldExampleState createState() => _WhisperTextFieldExampleState();
}
class _WhisperTextFieldExampleState extends State<WhisperTextFieldExample> {
final WhisperController _whisperController = WhisperController();
TextEditingController _textEditingController = TextEditingController();
@override
void dispose() {
_whisperController.dispose();
_textEditingController.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
WhisperTextField(
controller: _textEditingController,
whisperController: _whisperController,
decoration: InputDecoration(
labelText: 'Enter Sensitive Information',
),
onWhisperStatusChanged: (status) {
// Handle whisper status change if needed
print('Whisper status changed: $status');
},
),
SizedBox(height: 20),
ElevatedButton(
onPressed: () {
// Get the text from the WhisperTextField
String sensitiveText = _textEditingController.text;
// Handle the sensitive text securely
print('Sensitive text: $sensitiveText');
},
child: Text('Submit'),
),
],
);
}
}
注意事项
- WhisperController：
WhisperController用于控制WhisperTextField的隐私保护状态，比如开启或关闭模糊化。 - onWhisperStatusChanged：这是一个回调函数，当WhisperTextField的隐私保护状态改变时会被调用。
- 安全处理：在实际应用中，获取到的敏感信息应该进行安全处理，比如加密存储或传输。
请确保你已经正确安装并配置了whisper_flutter插件，并根据你的实际需求调整上述代码。如果你需要更高级的功能，比如自定义模糊效果或动态隐私控制，请参考插件的官方文档。
