Packages

• We used expo Media Library for getting the data from user's phone.
• We used a modified version of expo-video-player to play videos. It is available in our repo.
• We used a modified version of react-native-stories-view for the story style view on top of gallery, which is available in our repo.
• We used RecyclerListView from FlipKart, as the scrollView for the photos.
• We used react-native-reanimated for animations.
• We used Recoil for state management.
• We used react-native-gesture-handler for gesture handling.
• We used @react-navigation/bottom-tabs and @react-navigation/native for navigation.

Pages structure

For now we have two pages in the app:

• The HomePage that is the main page for showing the media files.
• The PermissionError page that is the page we show when there is permission error from user's phone.
• We are working on creating the "Library" and "Search" pages.
