From the Meteor mobile guide:
The file serving mechanism used in Meteor allows for local file access through URLs of the form http://localhost:/local-filesystem/) however. You can construct these file system URLs manually, or use WebAppLocalServer.localFileSystemUrl() to convert file:// URLs. You can use this to convert URLs received from plugins like cordova-plugin-file and cordova-plugin-camera for example.
Can anybody point me to anything at all that tells me where WebAppLocalServer.localFileSystemUrl() comes from? - code, documentation, an example? There is nothing in Google, I haven’t found the code base, it’s all very mysterious.
I asked this question in Stackoverflow, but unfortunately got no reply
