import {login} from '@react-native-seoul/kakao-login';

const signInWithKakao = async () => {
    const token = await login();
    setResult(JSON.stringify(token));
  };

💫

        <TouchableOpacity>
 
          <Image source={require('./images/sample_image_button.png')} />
          
        </TouchableOpacity>

이렇게 KakaoButton.js를 만들고
WelcomeScreen.js에서

<KakaoButton onClick={SignInWithKakao} />

를 했는데

    <TouchableOpacity style={styles.iconbutton} onPress={signInWithKakao}>
      <Image source={require('../assets/Kakao.png')} />
    </TouchableOpacity>

처럼 TouchableOpacity에서 설정해야함
