Enter key is not working properly (the cursor is not updated to the newline) in Text Fields #19371
Description
The flutter is the latest version. I just ran flutter upgrade.
$ flutter doctor
[✓] Flutter (Channel master, v0.5.7-pre.118, on Linux, locale en_US.UTF-8)
[✓] Android toolchain - develop for Android devices (Android SDK 27.0.3)
[✓] Android Studio (version 2.3)
It's hard for me to describe the bug in English so that I uploaded three screenrecords. Both bug01.mp4 and bug02.mp4 are the bug behaviors. expect.mp4 is what I expect in a normal native app.
Basically, when I input words in text fields and press Enter, the cursor is always not updated to the next new line and the cursor is still in the old line. (this is not expected) That will cause some weird observation. When the cursor is still in the old line and I input some words, the new inputs will jump to next line. Something like that.
PS:
Actually, I found this incorrect Enter key behavior 7 months ago and filed a bug in some community app project. I didn't pay too much attention on this bug because I think it's too obvious and everyone should notice it. I thought the bug should be fixed very soon. But I was wrong and after about a year, the most obvious bug is still here.

I can reproduce this on iOS but not on Android, might be specific to the iOS text handling

@jonahwilliams Sorry, no. I don't have iOS mobiles at all. I can reproduce this on all different Android mobiles, such as Android 8.1, Android 7.1.1, Android 5.1.1 etc... And the screenrecords I posted are from android 8.1.
Thanks a lot for the investigation and reply. I hope this bug can be fixed soon since I plan to write a wiki app which will use text fields heavily.

@sgon00 you're right, I can reproduce this on android devices as well.

The issue appears to be that TextAffinity is not updated from upstream to downstream when a newline is inserted

I think this is a dup of #15572
and I can still reproduce with
