window.resolveLocalFileSystemURL error

I’m using the camera plugin and i get a full path where the image is saved, and then i try to get the file with window.resolveLocalFileSystemURL(path)…
But i’m getting this error: Property ‘resolveLocalFileSystemURL’ does not exist on type ‘Window’.
I’m using the rc0 version, anyone can help me?
i’ll upload it to firebase, so i need an blob or a file.
