RecorderPlaybackController class Null safety

This class is a Provider style widget designed to co-ordinate a SoundRecorderUI and a SoundPlayerUI so that a user can record and playback in a co-ordinated manner.

All instances of SoundRecorderUI and a SoundPlayerUI will search the widget tree looking for a RecorderPlaybackController. This can cause unintended links. Always place the RecorderPlaybackController as close to the SoundRecorderUI and SoundPlayerUI as possible to avoid unintended links.

The RecorderPlaybackController will disable the SoundPlayerUI whilst recording is running and re-enable it once recording has stopped.

If recording is started whilst the SoundPlayerUI is playing then the recorder will cause the playback to stop.

The RecorderPlaybackController will also stream duration updates to the Player so that it can show the duration of the recording as it grows.
