Hey Android developers! 🧑‍💻👩‍💻 Have you been struggling with network state management in your Android projects? Good news — the [**Network State Utils**](https://github.com/JimmyMcBride/NetworkStateUtilsLib) library is here to simplify the process and offer seamless integration with Jetpack Compose to update your UI! 💪📚📲

## Step 1: Easily Install the Library 📥

Add the package to your project by first including jitpack in your root build.gradle:

```groovy
allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}
```

Then, add the dependency to your module gradle:

```groovy
dependencies {
    implementation 'com.github.JimmyMcBride:NetworkStateUtilsLib:1.0.1'
}
```

## Step 2: Leverage the NetworkState Sealed Class 🌟

`NetworkState` helps you manage your network requests' current status. States include `Idle`, `Loading`, `Success`, and `Error`. Take control of UI updates during specific network states!

```kotlin
sealed class NetworkState<out T> {
    object Idle : NetworkState<Nothing>()
    object Loading : NetworkState<Nothing>()
    data class Success<T>(val data: T) : NetworkState<T>()
    data class Error(val message: String) : NetworkState<Nothing>()
}
```

## Step 3: duringState & DuringComposableState 🔀

Using `duringState` and `DuringComposableState`, handle what happens at various network states. Achieve seamless integration with classic view models or Jetpack Compose!

```kotlin
networkEvent.duringState(
    success = { data -> onSuccess(data) },
    error = { message -> onError(message) },
    loading = { onLoading() },
    idle = { onIdle() }
)
```

```kotlin
networkEvent.DuringComposableState(
    success = { data ->
        Text(data.name)
    },
    error = { message ->
        Text("N/A")
        showSnackbar(message)
    },
    loading = { CircularProgressIndicator() },
    idle = {}
)
```

## Step 4: ConsumeNetworkEvent 🔄

Use `ConsumeNetworkEvent` to reset `NetworkState` back to Idle after a specific event. It resets the state, ensuring your UI remains fresh for subsequent updates!

```kotlin
ConsumeNetworkEvent(
    networkEvent = addCityEvent,
    consumeEvent = citiesViewModel::consumeAddCityEvent,
    onSuccess = {
        isLoading = false
        navController.popBackStack()
    },
    onError = {
        isLoading = false
    },
    onLoading = { isLoading = true }
)
```

## Step 5: Simplify with handleNetworkException & handleResponse 🛠️

Simplify your repository by using `handleNetworkException` and `handleResponse` for managing exceptions and responses during API calls.

```kotlin
fun <T> Response<T>.handleResponse(errorMessage: String = "Something went wrong.") =
    if (this.isSuccessful && this.body() != null)
        NetworkState.Success(data = this.body()!!)
    else
        NetworkState.Error(message = errorMessage)

suspend fun <T> handleNetworkException(apiCall: suspend () -> NetworkState<T>) = try {
    apiCall()
} catch (e: Exception) {
    NetworkState.Error(message = e.message.toString())
}
```
