Repository.kt

fun getProduct(id:Int): LiveData<Resource<Product>> { 
        val productData = MutableLiveData<Resource<Product>>()
        productData.value = Resource.Loading()
        productWebService
            .getProduct(id)
            .enqueue(object : Callback<Product> {
                override fun onResponse(
                    call: Call<Product>,
                    response: Response<JsonObject>
                ) {
                    if (response.isSuccessful && response.body() != null) {
                        productData.value = response.body()?.let { Resource.Success(it) }
                    } else {
                        productData.value = Resource.Error("No Data Found")
                    }
                }

                override fun onFailure(call: Call<Product>, t: Throwable) {
                    productData.value = Resource.Error("Error : ${t.message}")
                }
            })
        return productData
    }
