Unhandled Exception: FileSystemException: File closed

[mixable]

I want to use LocalStorage with different files (keys). Each of the files is opened with LocaleStorage('my_file.ext'). I always open only one file, there are not multiple files open at the same time.

When working on Windows, I have to call the dispose() method to close a file before opening another. This is necessary to release the file handle. This works as expected, calling dispose() before opening another file will release the file handle. If dispose() is not called, the file cannot be edited or deleted until the app is closed.

When opening the same file again, LocalStorage uses the file instance stored in _cache map. As the file handler has been disposed, the following exception is thrown:

Unhandled Exception: FileSystemException: File closed, path = '...'

To make this work, it is necessary to remove the instance from _cache, when calling dispose(). Otherwise it's not possible to read or write the same file later. This is also a problem when you handle files with the same name but in different paths.
