+# SavedStateHandle Integration
+
+**eungabi 0.4.0** introduces a powerful SavedState mechanism, enabling seamless state preservation and data transfer in conjunction with ViewModels. With this new feature, each ViewModel can now access a `SavedStateHandle` object, a key-value map that allows you to store and retrieve data directly within the ViewModel.
+Crucially, the data within the ViewModelSavedState persists even through process termination and configuration changes, ensuring that your ViewModel's state remains intact.
+
+## Using SavedStateHandle in EunGabi
+
+EunGabi provides several convenient ways to utilize `SavedStateHandle` for managing state across navigation events. Here are the primary methods:
+
+### 1. Accessing SavedStateHandle via `EunGabiController`
+
+You can access the `SavedStateHandle` of a specific `EunGabiEntry` by leveraging the `EunGabiController.backStack`. This allows you to retrieve the `SavedStateHandle` from any entry within the navigation back stack.
+```kotlin
+val controller = rememberEunGabiController()
+val backStack by controller.backStack. collectAsState()
+val handle = backStack.last().savedStateHandle val viewModel = viewModel { ViewModel(handle) }
+```
+
+**Explanation:**
+*   `rememberEunGabiController()`: Retrieves the current `EunGabiController` instance.
+*   `controller.backStack.collectAsState()`: Collects the current state of the back stack as a `State` object.
+*   `backStack.last().savedStateHandle`: Accesses the `SavedStateHandle` of the most recent entry in the back stack.
+* `viewModel { ViewModel(handle) }`: Creates a ViewModel instance with the SavedStateHandle.
+
+
+
+### 2. Accessing SavedStateHandle within `NavGraphBuilder.composable()`
+
+Within the content block of `NavGraphBuilder.composable()`, you can directly access the `SavedStateHandle` of the current `EunGabiEntry`.
+```kotlin 
+NavHost(...) { 
+	composable(...) { entry -> 
+		val handle = entry.savedStateHandle
+		val viewModel = viewModel { ViewModel(handle) } 
+	}
+}
+```
+
+**Explanation:**
+
+*   `composable(...) { entry -> ... }`: The `composable` function provides the current `EunGabiEntry` as a parameter.
+*   `entry.savedStateHandle`: Directly accesses the `SavedStateHandle` associated with the current entry.
+* `viewModel { ViewModel(handle) }`: Creates a ViewModel instance with the SavedStateHandle.
+
+### 3. Using Parameter Default Values with `eunGabiViewModel()`
+
+For a more streamlined approach, you can use the `eunGabiViewModel(...)` function to inject the `SavedStateHandle` directly into your composable function's parameters.
+
+`eunGabiViewModel` automatically recognizes the currently active `EunGabiEntry` and provides the corresponding `SavedStateHandle`.
+
+```kotlin
+@Composable 
+fun EunGabiScreen( 
+	viewModel: EunGabiViewModel = eunGabiViewModel { handle -> EunGabiViewModel(handle)  }
+) { ... }
+```
+
+**Explanation:**
+
+* `eunGabiViewModel { handle -> EunGabiViewModel(handle) }`: This function automatically provides the correct `SavedStateHandle` to the lambda, which you can then use to create your `EunGabiViewModel`.
+* `EunGabiViewModel(handle)`: Creates a EunGabiViewModel instance with the SavedStateHandle.
+
+### Hilt Integration
+
+When using Hilt in your Android target, you can seamlessly inject the appropriate `SavedStateHandle` using `hiltViewModel()`.
+
+```kotlin
+@Composable  
+fun HiltView(viewModel: HiltViewModel = hiltViewModel()) {  
+    val state by viewModel.state.collectAsState()  
+    Text(text = state, modifier = Modifier.testTag("state"))  
+}
+```
+**Explanation:**
+
+* `hiltViewModel()`: This Hilt function automatically provides the correct `SavedStateHandle` to your `HiltViewModel`.
+* `viewModel.state.collectAsState()`: Collects the current state of the ViewModel.
+
+!!! tip  
+    For a practical example of Hilt integration, refer to the [EunGabiHiltTest.kt](https://github.com/easternkite/eungabi/blob/main/androidApp/src/androidTest/kotlin/com/easternkite/eungabi/android/EunGabiHiltTest.kt) file in the EunGabi repository.
+
+### Koin Integration
+
+Similarly, when using Koin in your KMP project, you can easily inject the `SavedStateHandle` using `koinViewModel()`. Koin, like Hilt, internally recognizes the current entry and provides the correct `SavedStateHandle`.
+
+```kotlin
+@Composable  
+fun KoinView(  
+    viewModel: KoinViewModel = koinViewModel()  
+) {  
+    val state by viewModel.state.collectAsState()  
+    Text(text = state, modifier = Modifier.testTag("state"))  
+}
+```
+
+**Explanation:**
+
+* `koinViewModel()`: This Koin function automatically provides the correct `SavedStateHandle` to your `KoinViewModel`.
+* `viewModel.state.collectAsState()`: Collects the current state of the ViewModel.
+
+!!! tip  
+    For a practical example of Koin integration, refer to the [KoinViewModelTest.kt](https://github.com/easternkite/eungabi/blob/main/shared/src/desktopTest/kotlin/com/easternkite/eungabi/KoinViewModelTest.kt) file in the EunGabi repository.
