Is it a Kana input language you are using ? What is the expected behavior upon following the replication steps ?
Can you provide a short video from previous version where it worked ?
cafelafe commentedon May 27, 2024
@darshankawar
Yes, it is a Kana input language
Flutter version 3.19.6 will look like the video below.

Thanks for the update. Using above details, I was able to verify and replicate the reported behavior. Looks like it is related to unicode text.
Also learned more about full-width space:
Full-width is used for fields where you will need to type Japanese letters (your mail address, etc.)—in which case, the alphanumeric must be input using full-width.Since it worked in latest stable but not in current, I'll label this as regression.
stable, master flutter doctor -v

I have checked the Unicode Zs category and the same problem exists in all codes except
U+0020,U+00A0andU+202F.https://www.compart.com/en/unicode/category/Zs
The behavior of the three characters was compared between Flutter 3.19 and Flutter 3.22. Text is copied and pasted multiple times. Then I type
abc.Flutter 3.19.6
3.19.mov
Flutter 3.22.2
3.22.mov
