Flutter Doctor output

version of flutter 3.13 and 3.16 . 3.10 is ok;

[wanjm]

it is reproducible with ipad that can use pencil but don't need to be connected;

[danagbemava-nc]

Hi @wanjm, what iPad are you testing on? What version of iOS is it running and what generation of apple pencil does it use?

I tested this on my iPad Air M1 running iOS 17.2 with a 2nd gen apple pencil and I can't seem to reproduce the issue.

Also, what version of flutter specifically are you using? If you could provide any more details that could help us reproduce, that would be appreciated.

Please file new issues regarding the comments I have hidden as off topic so that they can be tracked separately. Please check for duplicates before filing the issues.

Thank you

[wanjm]

1. flutter 3.13.9 and 3.16.9 and master (4601341)
2. iPad 15.2 (7th generation) and iPad 16.5.1(6th generation)
3. just use the ipad with apple pencil support, but when test , you should use your finger instead of apple pencil, and you need to input Chinese character; other Character will not trigger such problem;

[danagbemava-nc]

Hi @wanjm, I just tried again but still can't repro. Kindly see the video below and let me know if I'm missing anything.

Thank you

you need to use "right-bottom" key on keyboard to fold the keyboard, from your mp4, it seems step 3 is different; could you please check you do as i asked;

1. tap red area => the area will change to green to show EditableText; (green without active EditableText)
2. click green area to focus the EditableText, then keyboard is displayed on the screen; (now EditableText is active and cursor is shine)
3. input one character (Chinese character) and then fold the keyboard with bottom-right key on keyboard, ( ** now you can see green area but EditableText is not active** );
4. click white area again to dismiss the EditableText; (change to red);
5. click the red area, it should change to green, but it is still red with keyboard popup;

please see my video

[wanjm]

maybe you can try #142437 @danagbemava-nc

[wanjm]

@danagbemava-nc

1. please use the PinYin Input method; (Chinese, Simplified, - Pinyin)
2. please use change your input method to Simplified Chinese

When build with flutter 3.10 there is no such problem;

[danagbemava-nc]

Hi @wanjm, I am using the Simplified keyboard and I am also using the button that dismissed the keyboard on the ipad (not the done button). See the recording below

Can you try upgrading to the latest version of iOS to see if you still have this issue?

RPReplay_Final1706682903.MP4

[wanjm]

@danagbemava-nc could you please find a pad with old version;
I find another 16.6.1 also have such problem;
many of our users are using 16.6 and below. through 17 has no such issue, I still need to fix it; and I will try to find one 17 pad;

[wanjm]

@danagbemava-nc I tested it on 17.1, there is no such problem;
could you please find iPad of 15 or 16, and try again.
thanks;

BTW： will flutter team fix this bug if you can reproduce it in IOS 15 or 16;

[huycozy]

@wanjm I check this issue on a simulator (iPad Pro, 12.9 inch, 5h gen, iOS 16.4 - support Apple Pencil) but don't see the issue. My result is similar to Daniel's demo above.

This could be a device-specific issue. Could you try upgrading to the latest master channel and retry?

flutter channel master
flutter upgrade

[wanjm]

I have tested on master, there is such problem;
I don't think this is device-specific issue, for I have found 3 pad, all have this problem;

[huycozy]

I just checked this on a physical device (iPad Air 5) but still can't reproduce the issue. Labeling the issue for further information. If you can find any clues, please write in comments.

[MitchellGoodwin]

Labelling this as p3 due to the difficulty to reproduce and how odd this case is. Will change priority if it turns out to be more common.
