-- Bug fix in `SftpFileWriter`:
+- Bug fix in `SftpFileWriter` for [#50](https://github.com/TerminalStudio/dartssh2/issues/50), [#71](https://github.com/TerminalStudio/dartssh2/issues/71), [#100](https://github.com/TerminalStudio/dartssh2/issues/100):
 
   When the input stream contains only one event and that event has fewer bytes than `maxBytesOnTheWire`, then the `SftpFileWriter._doneCompleter` never got completed. This happened because the completer got only completed in the `_handleLocalData` event handler if the `_streamDone` flag was already true, the problem is that if the stream only has one small event, then `_handleLocalData` will only be called once with the event and afterward `_handleLocalDone` will be called once, which sets `_streamDone` to true. At this point the `_doneCompleter` cannot be completed anymore because the `_handleLocalData` will not get called anymore. This problem causes never ending `await` statements when opening and writing a file.
