Flutter Speech to Text在Android上不起作用

<uses-permission android:name="android.permission.RECORD_AUDIO" />

import 'package:permission_handler/permission_handler.dart';

PermissionStatus status = await Permission.microphone.request();
if (status.isGranted) {
  // 录音权限已授予，可以使用Speech to Text插件
} else {
  // 录音权限被拒绝
}

import 'package:speech_to_text/speech_to_text.dart' as stt;

stt.SpeechToText speech = stt.SpeechToText();
bool isAvailable = await speech.initialize();
if (isAvailable) {
  // 设备支持语音转文本功能，可以使用Speech to Text插件
} else {
  // 设备不支持语音转文本功能
}
