[iOS][iPad]: Textfield not responding to `CMD+C` and `CMD+V` shortcuts using external keyboard #98832

nero-angela · 2022-02-20T16:06:26Z

Copy (CMD + C) and paste (CMD + V) shortcuts do not work on iPad when using an external keyboard.
There were no problems with the iPhone.

Steps to Reproduce

On the iPad, type on an external keyboard.
Write text in TextField.
Select an article and press CMD + C to copy it.
Press CMD + V to paste.

sample code

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: const [
            Padding(
              padding: EdgeInsets.all(8.0),
              child: TextField(),
            ),
          ],
        ),
      ),
    );
  }
}

flutter doctor -v

Verified this behavior on latest master and stable using iPad Pro (4th gen) and observed that typing from external keyboard (e.g bluetooth) works, but copy paste isn't working, as shown below:

98832_i.mov

The same scenario works properly on iOS simulator whereing typing and copy paste seems to work as expected, as below:

98832_s.mov

When using cmd+c and cmd+v on simulator, the simulator displays a message on top of it CorSimulatorBridge pasted from {app name}`, but the same doesn't seem to trigger on iPad.

This behavior was fixed as part of this issue: #70104, PR : flutter/engine#28971 but seem to have come back.

stable, master flutter doctor -v

Labeling it as a regression, since this was fixed but still occuring on latest versions.

Thanks @darshankawar for spotting the commits in the regression. Marking this a P2. cc @jmagman

jmagman · 2022-02-23T01:52:25Z

@cyanglaz is looking at this.

doppio · 2022-02-25T04:16:29Z

Is this likely the same issue as #68514? Supposedly PR: flutter/engine#28971 had fixed that as well, but I'm seeing it on stable. If this regression is unrelated, I can file another issue.

I'm seeing it (#68514) too on stable channel. It's not in 2.8.x, but seems to appear from 2.10.0.

cyanglaz · 2022-02-25T17:29:32Z

The issue is that https://github.com/flutter/engine/blob/main/shell/platform/darwin/ios/framework/Source/FlutterTextInputPlugin.mm#L1051 prevented the actions to go through, as when it is on iPad Pro, IsScribbleAvailable returns true.
This was introduced in: flutter/engine#24224 to support scribble handwriting.

A simple fix could be just allow actions like copy and paste passing through regardless of IsScribbleAvailable(). I don't understand how scribble works to be certain that this won't have other side effects, or break the scribble logic.

Maybe @justinmc, @gaaclarke, @LongCatIsLooong or @fbcouch can provide some advices?

justinmc · 2022-02-25T18:25:21Z

Thanks for tracking that down @cyanglaz. I'll try a few solutions after my engine compiles.

cyanglaz · 2022-02-25T19:24:05Z

@justinmc Great! Thanks, feel free to assign yourself if you plan to work on it :)

justinmc · 2022-02-26T01:25:48Z

it looks like that NO was added because otherwise the paste notification shows up on every keypress ("[appname] pasted from ...").

I think I have a fix in flutter/engine#31691. Trying to get the tests working so I can write one...

jmagman · 2022-02-28T21:42:26Z

Thank you @justinmc!
