1. MainActivity.kt

package com.example.mylogin

    }

    var password by remember {
        mutableStateOf("")
    }

    Column(
        modifier = Modifier.fillMaxSize(),
        verticalArrangement = Arrangement.Center,
        horizontalAlignment = Alignment.CenterHorizontally
    ){
        Image(painter = painterResource(id = R.drawable.image), contentDescription = "Login Image",
            modifier = Modifier.size(200.dp))

        Text(text = "Selamat Datang", fontSize = 36.sp, fontWeight = FontWeight.SemiBold)
        Spacer(modifier = Modifier.height(16.dp))
        Text(text = "Login ke akun Anda!")
        Spacer(modifier = Modifier.height(16.dp))
        OutlinedTextField(value = email, onValueChange = { email = it  }, label = {
            Text(text = "Email Address")
        })

        OutlinedTextField(value = password, onValueChange = {
            password = it
        }, label = {
            Text(text = "Password")
        }, visualTransformation = PasswordVisualTransformation()
        )
        Spacer(modifier = Modifier.height(16.dp))
        Button(onClick = {
            Log.i("Credential", "Email : $email Password : $password")

        })
        Spacer(modifier = Modifier.height(32.dp))
        Text(text = "Login dengan")

        Spacer(modifier = Modifier.height(16.dp))

        Row(
            modifier = Modifier.fillMaxWidth().padding(40.dp),
            horizontalArrangement = Arrangement.SpaceEvenly
        ) {
            Image(painter = painterResource(id = R.drawable.google) ,
                contentDescription = "Google",
                modifier = Modifier
                    .size(60.dp)
                    .clickable {
                        //google clicked
                    }
            )
            Image(painter = painterResource(id = R.drawable.facebook) ,
                contentDescription = "Facebook",
                modifier = Modifier
                    .size(60.dp)
                    .clickable {
