Media Object

const media = {
  thumb: '', // thumbnail version of the photo to be displayed in grid view. actual photo is used if thumb is not provided
  photo: '', // a remote photo or local media url
  id: 1, // unique identifer for the photo; can be omitted if the `thumb`/`photo` will always be unique
  caption: '', // photo caption to be displayed
  selected: true, // set the photo selected initially(default is false)
};

Progress Component

Android

Built-in ActivityIndicator component is used for Android. Any additional configuration is not needed.

iOS

react-native-progress component is used as progress indicator. The default progress component is Progress.Bar. You can also use Progress.Circle component by simply using useCircleProgress prop, and adding ReactART library to your Xcode project. For more information please check out react-native-progress repo and React Native documentation.

Sharing

I tried delivering sharing photo feature but it was complicated to provide for iOS and android out of the box. I now believe it's a better idea to separate sharing logic into another module. Please check out Example project to see a basic ActionSheetIOS implementation for iOS. You may also use available sharing libraries such as react-native-activity-view and react-native-share.
