Textinput bug on Samsung device

[seritaApp]

Tested with flutter gallery app on Samsung Galaxy Tab S4

1. Begin to type a word
2. Leave keyboard mode
3. Refocus and continue typing
   Instead of adding the new characters, the previous word gets repeated again
   Happens even on the gallery app so it's not related to my code.

Edit: I was trying to type "words" here

@seritaApp thanks. It could be related to flutter/engine#12432 since you are using a version of Flutter that includes it. I do think it's unlikely though because that code shouldn't behave any differently when using a non-Korean input method like in the reproduction GIF. This looks like a duplicate of #31512 to me.

If you see the problem consistently now, do you mind testing out an earlier version of Flutter and seeing if you still see it? That would help narrow it down some. flutter channel dev would switch to a week old version at this point that doesn't have that new commit.

I have tested it in dev, beta and stable and can reproduce the issue. I have also downloaded apps from the Playstore which were made with flutter according to itsallwidgets.com and they all had the issue.

Yep you are right, it's probably a duplicate of #31512

[justinmc]

Maybe that engine fix needs to happen for English input as well as Korean?

CC @GaryQian since we were just talking about this.

Okay, thank you for the detailed reproduction info @seritaApp . I'm going to close this as a duplicate of #31512.

@justinmc I'm not totally convinced that the restart IMM engine fix actually covers this issue, or is the least invasive fix for it. It may, just not sure. If we get repro though we could test it out and enable it for all Samsung keyboards if that makes sense.
