**Note:** If you are still using deprecated version 2.x.x [check](https://github.com/react-native-image-picker/react-native-image-picker/tree/2.3.4) this for documentation.

## Migration from 2.x.x to 3.x.x

- `showImagePicker` API is removed.
- No permission required for default `options` on Android.
- Removed and updated some values in `options`, so please check them carefully.

# Install

```
yarn add react-native-image-picker

# RN >= 0.60
cd ios && pod install

# RN < 0.60
react-native link react-native-image-picker
```

## Post-install Steps

### iOS

Add the appropriate keys to your Info.plist,

If you are allowing user to select image/video from photos, add `NSPhotoLibraryUsageDescription`.

If you are allowing user to capture image add `NSCameraUsageDescription` key also.

If you are allowing user to capture video add `NSCameraUsageDescription` add `NSMicrophoneUsageDescription` key also.

### Android

No permissions required (`saveToPhotos` requires permission [check](#note-on-file-storage)).

Note: This library does not require Manifest.permission.CAMERA, if your app declares as using this permission in manifest then you have to obtain the permission before using `launchCamera`.

## Note on file storage

Image/video captured via camera will be stored in temporary folder so will be deleted any time, so don't expect it to persist. Use `saveToPhotos: true` (default is false) to save the file in the public photos. `saveToPhotos` requires WRITE_EXTERNAL_STORAGE permission on Android 28 and below (You have to obtain the permission, the library does not).
