requestFileSystem method
Access a sandboxed file system of size bytes.
If persistent is true, the application will request permission from the
user to create lasting storage. This storage cannot be freed without the
user's permission. Returns a Future whose value stores a reference to
the sandboxed file system for use. Because the file system is sandboxed,
applications cannot access file systems created in other web pages.
Implementation
Future<FileSystem> requestFileSystem(int size, {bool persistent: false}) {
return _requestFileSystem(persistent ? 1 : 0, size);
}
