Migrates camera implementation as part of flutter/flutter#119109

Resolves flutter/flutter#170439. This PR migrates the last one of the problematic methods (startImageStream) to Switft, which resolves the issue.

This PR migrates the 8th chunk of FLTCam class to Swift:

  • startImageStream
  • setUpCaptureSessionForAudioIfNeeded
  • reportErrorMessage (ObjC implementation removal)

Some properties of the FLTCam have to be temporarily made public so that they are accessible in DefaultCamera.

Pre-Review Checklist

If you need help, consider asking for advice on the #hackers-new channel on Discord.

Note: The Flutter team is currently trialing the use of Gemini Code Assist for GitHub. Comments from the gemini-code-assist bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.

Footnotes

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Code Review

This pull request continues the migration of the camera_avfoundation plugin from Objective-C to Swift. It successfully migrates startImageStream and setUpCaptureSessionForAudioIfNeeded, and removes the old Objective-C code. The changes are mostly a direct translation, but I found a critical issue in the new setUpCaptureSessionForAudioIfNeeded implementation where a class property was not being set, which could lead to a crash. I've provided a suggestion to fix this.
