+# Reply sample
+
+This sample is a [Jetpack Compose][compose] implementation of [Reply][reply], a Material Design study for adaptive design.
+
+To try out this sample app, you need to use 
+[Android Studio Canary](https://developer.android.com/studio).
+[Resizeable Emulator](https://developer.android.com/about/versions/12/12L/get#resizable-emulator)
+You can clone this repository or import the
+project from Android Studio following the steps
+[here](https://developer.android.com/jetpack/compose/setup#sample).
+
+This sample showcases:
+
+* Adaptive apps for mobile, tablets and foldables 
+* Material navigation components
+* [Material 3 theming][materialtheming] & dynamic colors.
+
+## Screenshots
+
+<img src="screenshots/reply.gif"/>
+
+## Features
+
+#### [Dynamic window resizing](app/src/main/java/com/example/reply/ui/ReplyApp.kt#74)
+The [WindowSizeClass](https://developer.android.com/reference/kotlin/androidx/compose/material3/windowsizeclass/WindowSizeClass) allows us to get to know about current device size and configuration 
+and observe any changes in device size in case of orientation change or unfolding of device.
+
+#### [Dynamic fold detection](app/src/main/java/com/example/reply/ui/MainActivity.kt#56)
+The [WindowLayoutInfo](https://developer.android.com/reference/kotlin/androidx/window/layout/WindowLayoutInfo) let us observe all display features including [Folding Postures](app/src/main/java/com/example/reply/ui/utils/WindowStateUtils.kt)
+real-time whenever fold state changes to help us adjust our UI accordingly. 
+
+#### [Material 3 navigation components](app/src/main/java/com/example/reply/ui/navigation/ReplyNavigationComponents.kt)
+The sample provides usage of  material navigation components depending on screen size and states. These components also are part of material guidelines for canonical layouts to improve user experience and ergonomics.
+* [`BottomNavigationBar`](app/src/main/java/com/example/reply/ui/navigation/ReplyNavigationComponents.kt#162) for compact devices.
+* [`NavigationRail`](app/src/main/java/com/example/reply/ui/navigation/ReplyNavigationComponents.kt#70) for medium size devices. It is also used along with [`ModalNavigationDrawer`](app/src/main/java/com/example/reply/ui/ReplyApp.kt#73) when user want to see more content.
+* [`PermanentNavigationDrawer`](app/src/main/java/com/example/reply/ui/ReplyApp.kt#153) for large devices.
+* Depending upon the different size and state of device correct [navigation type](app/src/main/java/com/example/reply/ui/ReplyApp.kt#71) is chosen dynamically. 
+
+#### [Material 3 Theming](app/src/main/java/com/example/reply/ui/theme)
+Reply is using brand new Material 3 [colors](app/src/main/java/com/example/reply/ui/theme/Color.kt), [typography](app/src/main/java/com/example/reoly/ui/theme/Type.kt) and [theming](app/src/main/java/com/example/reply/ui/theme/Theme.kt). It also supports both [light and dark mode]((app/src/main/java/com/example/reply/ui/theme/Theme.kt#95)) depending on system settings.
+[Material Theme builder](https://material-foundation.github.io/material-theme-builder/#/custom) is used to create material 3 theme and directly export it for Compose.
+
+#### [Dynamic theming/Material You](app/src/main/java/com/example/reply/ui/theme/Theme.kt#100)
+On Android 12+ Reply supports Material You dynamic color, which extracts a custom color scheme from the device wallpaper. For older version of android it falls back to defined light and dark [color schemes](aapp/src/main/java/com/example/reply/ui/theme/Theme.kt#34)
+
+#### [Inbox Screen](app/src/main/java/com/example/reply/ui/ReplyListContent.kt)
+Similar to navigation type, depending on device's size and state correct [content type](app/src/main/java/com/example/reply/ui/ReplyApp.kt#72) is chosen, we can have [Inbox only](app/src/main/java/com/example/reply/ui/ReplyListContent.kt#91) or [Inbox and thread detail](app/src/main/java/com/example/reply/ui/ReplyListContent.kt#83) together  
+
+#### [FAB & Material 3 components](app/src/main/java/com/example/reply/ui/ReplyListContent.kt)
+Reply is using all material 3 components including different type of FAB for different screen size and states.
+* [`LargeFloatingActionButton`](app/src/main/java/com/example/reply/ui/ReplyListContent.kt#100) is used along with bottom navigation ber.
+* [`FloatingActionButton`](app/src/main/java/com/example/reply/ui/navigation/ReplyNavigationComponents.kt#87) is used with Navigation rail for medium to large tablets.
+* [`ExtendedFloatingActionButton`](app/src/main/java/com/example/reply/ui/navigation/ReplyNavigationComponents.kt#214) is used in Navigation drawer for large devices.
+
+## [Data](app/src/main/java/com/example/reply/data)
+Reply has static local data providers for [email](app/src/main/java/com/example/reply/data/local/LocalEmailsDataProvider.kt) and [account](app/src/main/java/com/example/reply/data/local/LocalAccountsDataProvider.kt) data. It is also using repository pattern where [EmailRepository](app/src/main/java/com/example/reply/data/EmailsRepository.kt) 
+emits the flow of email from local data that is used in [ReplyHomeViewModel](app/src/main/java/com/example/reply/ui/ReplyHomeViewModel.kt) to observe 
+it in view model scope. ViewModel expose this data to ReplyApp composable via [state flow](app/src/main/java/com/example/reply/ui/ReplyHomeViewModel.kt#34).
