unmount method
Unmounts a file system with the given fileSystemId
. It
must be called after onUnmountRequested is invoked. Also,
the providing extension can decide to perform unmounting if not requested
(eg. in case of lost connection, or a file error).
In case of an error, runtime.lastError
will be set with a
corresponding error code.
Implementation
Future<void> unmount(UnmountOptions options) async {
await promiseToFuture<void>(
$js.chrome.fileSystemProvider.unmount(options.toJS));
}
