[p:camera] Make it possible to switch camera while recording a video

[sarbogast]

Use case

Right now, the cameraDescription is set when you create a new CameraController instance, and you can't change it after that. Sometimes, when I record a video, I want to be able to switch from the front-facing to the back-facing camera mid-recording to show something. Certain packages like camerawesome allow that but only on iOS.

Proposal

Add a setCamera(CameraDescription) method to CameraController, that can be called while recording, or at the very least when the controller is paused so that we can pause, switch and resume in the same file.

This functionality is a must for any modern app. Is there a limitation why there is no PR opened for this functionality yet like native side blockers?

[tjcampanella]

I agree this is a necessary feature.

Is there any workaround for it?

has there been a fix to the issue?

For anyone interested in implementing this, flutter/plugins#4445 was a work-in-progress PR that could serve as a starting point.
