[Bug]: Text editor cursor Issue with long text

[haroke4]

Package Version

4.2.5

Flutter Version

3.22.2

Platforms

iOS

How to reproduce?

After copying the base code example code for customizing image editor from pub.dev and running it as-is, I noticed some unusual cursor behavior.

When I input a significant amount of text, the cursor starts behaving awkward:

To reproduce the bug:

1. Copy and paste the example code from example code section.
2. Enter a long string of text into the text field, as demonstrated in the video.

Thank you for your amazing package and I am welcome to provide you with additional information if you wish

Thank you for reporting this issue with all the details. I can reproduce the problem and already know where the problem is. However, there are some other parts in the text editor that I didn't like, so I will rewrite some more code directly and maybe also replace the rounded_background_text package with my own solution. This will take a few days, but I will post here when I am done.

I have released version 4.2.7 which should fix the cursor issue. Please let me know if you still have the issue after you updated.

Btw, I haven't finished optimizing the text editor completely, this update only resolves that issue, but I still have a plan to optimize some other stuff about performance, hit detection and text overflow.
