Update all versions, specifically file which fixes some bugs that caused tests to fail if run in different orders:
- systemTemp directories created by MemoryFileSystem will allot names based on the file system instance instead of globally.
- MemoryFile.readAsLines()/readAsLinesSync() no longer treat a final newline in the file as the start of a new, empty line.
- RecordingFile.readAsLine()/readAsLinesSync() now always record a final newline.
The flake appears to be coming from the Google Maps plugin. This test
just needs a platform view plugin without the interface method
implemented in general, not Maps specifically. Update it here to avoid
the issue in Maps until that's fixed.
Create a very simple platform view implementation that exercises this
potential bug in order to create a minimal test case with less risk of
causing second order issues like depending on any kind of full package
would cause.
