Package Exports
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@huyboken/react-native-image-picker) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

| uri | OK | OK | OK | BOTH | NO | The file uri in app specific cache storage. Except when picking video from Android gallery where you will get read only content uri, to get file uri in this case copy the file to app specific storage using any react-native library. For web it uses the base64 as uri. |

| id | OK | OK | NO | BOTH | YES | local identifier of the photo or video. On Android, this is the same as fileName |
Note on file storage
Image/video captured via camera will be stored in temporary folder allowing it to 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 (The permission has to obtained by the App manually as the library does not handle that).
For web, this doesn't work.
ErrorCode
| Code | Description |
|---|---|
| camera_unavailable | Camera not available on device |
| permission | Permission not satisfied |
| others | Other errors (check errorMessage for description) |
