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.
