# Material3 BottomSheet Navigation

This library provides a navigation solution for Compose projects using Material3 BottomSheets. It allows you to define your BottomSheet as navigation routes, eliminating the need for the `androidx.compose.material.navigation` and ` androidx.compose.material:material` !
libraries. This simplifies your app's dependencies and ensures a consistent Material3 experience.
This library also leverages the new functionality from `androidx.navigation:navigation-compose:2.8.0-beta0X` to allow you to define routes with serialized classes.

## Implementation

You can follow the implementation approach used in the  [app](https://github.com/stefanoq21/BottomSheetNavigator3/tree/main/app "app") module. Alternatively, you can find a detailed explanation below.

### Dependencies
The library is now available on MavenCentral!!! 
Add the dependencies to your `libs.versions.toml`
```
[versions]
...
material3Navigation = "X.X.X" current release version

[libraries]
...
material3-navigation = { group = "io.github.stefanoq21", name = "material3-navigation", version.ref = "material3Navigation" }

```
In your `build.gradle.kts` implement your dependencies:
```
...
dependencies {
...
 implementation(libs.material3.navigation)
```
### Usage
Define your **BottomSheetNavigator**
```
...
   val bottomSheetNavigator =
                    rememberBottomSheetNavigator(skipPartiallyExpanded = true/false)
                val navController = rememberNavController(bottomSheetNavigator)
```
Add the **ModalBottomSheetLayout** on top of the **NavHost** component and pass the **bottomSheetNavigator** as parameter:
```
ModalBottomSheetLayout(
                        modifier = Modifier
                            .fillMaxSize(),
                        bottomSheetNavigator = bottomSheetNavigator
                    ) {
                        NavHost(
                            navController = navController,
                            startDestination = Screen.Home
                        ) {
...
```
Define your routes as strings or data class (depend on the compose navigation version you are using):
```
...
   bottomSheet<Screen.BottomSheetFullScreen> {
                                BSFullScreenLayout()
                            }
  bottomSheet("BottomSheetFullScreen") {
                                BSFullScreenLayout()
                            }
...
```
Everything is ready! Just navigate to your new destination as usual:
```
...
Button(onClick = { navController.navigate(Screen.BottomSheetFullScreen) }) {
                                        Text(text = "BottomSheetFullScreen")
                                    }
...
```

### Navigating Back from a Bottom Sheet

To implement a back or close button in your bottom sheet, I suggest to use `onBackPressedDispatcher.onBackPressed()`. This because if you use  `navController.popBackStack()` the animation will not appear. The animation was disabled, in this case, to avoid problems during the navigation that start from bottomshets.

### Customization

The library currently supports the same customization options of the standard `androidx.compose.material3.ModalBottomSheet`. You can customize the appearance of the all the bottomsheets used in your navigation graph by passing the parameters to the `ModalBottomSheetLayout`.
