Adding more examples for the flushSync method

Hey there, I'm the author of the following post https://giacomocerquone.com/keep-input-cursor-still/ where I showcased a few pain points while managing an input's cursor.
Earlier today I also noticed this tweet from Ryan Florence where he was showcasing the usage of the flushSync method in a similar way to the one I was going after using low-level asynchronicity js tools to tame the eventloop such as setTimeout, await Promise.resolve(), etc. etc.

Do you think we could add such examples in the docs or it's just an internal method not to be used so commonly?
Svelte has also something similar in its documentation/tutorial with the tick method https://learn.svelte.dev/tutorial/tick

首先定位现有的 flushSync 文档和示例，然后查看链接的光标管理文章以及 Ryan Florence 的示例，以了解相关用例。完成的标准是添加清晰的文档示例，或记录为什么不应普遍使用 flushSync，并确保相关指导与 React 预期的使用方式一致。
