## Pre-Review Checklist

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). 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.

…#11133)

We change the Indent class to not accept an IOSink. Instead, it manages all writes in its own StringBuffer, and then its `toString()` method can be used to extract out the written text.

This dramatically reduces the number of write operations sent to the OS. Functionally, it is a no-op, but should have various performance improvements. Generating Dart files may be overall faster.

Using this PR, I find that the number of file operations is reduced from 166k operations to 3142 operations. 🎉 

Fixes flutter/flutter#182958

The video player and display link won't necessarily be deallocated when the player is disposed, so the display link should be stopped at that point to avoid having it drive frame requests.
