Usage

import React, { useState, useEffect } from 'react';
import { SafeAreaView, Button, Text, View } from 'react-native';
import {
  startRecognition,
  stopRecognition,
  addRecognitionListener,
  removeRecognitionListener
} from 'voice-recognition-react-native';

const App = () => {
  const [recognizedText, setRecognizedText] = useState<string>('');
  const [isRecognizing, setIsRecognizing] = useState<boolean>(false);

  useEffect(() => {
    const handleResult = (result: string) => {
      setRecognizedText(result);
      console.log('Recognition result received: ', result);
    };

    const handleError = (error: string) => {
      console.error('Recognition error received: ', error);
      setIsRecognizing(false);
    };

    addRecognitionListener(handleResult, handleError);

    return () => {
      removeRecognitionListener();
    };
  }, []);

  const handleStartRecognition = async () => {
    try {
      console.log('Recognition started');
      setIsRecognizing(true);
      await startRecognition();
    } catch (error) {
      console.error('Recognition error: ', error);
      setIsRecognizing(false);
    }
  };

  const handleStopRecognition = () => {
    stopRecognition();
    setIsRecognizing(false);
    console.log('Recognition stopped');
  };

  return (
    <SafeAreaView style={{ flex: 1, justifyContent: 'center', alignItems: 'center', backgroundColor: '#000' }}>
      <Button title="Start Recognition" onPress={handleStartRecognition} disabled={isRecognizing} />
      <Button title="Stop Recognition" onPress={handleStopRecognition} disabled={!isRecognizing} />
      <View style={{ padding: 10, backgroundColor: '#333', borderRadius: 5, marginTop: 20 }}>
        <Text style={{ color: '#fff', fontSize: 16 }}>
          Recognized Text: {recognizedText}
        </Text>
      </View>
    </SafeAreaView>
  );
};

export default App;
