I couldn't reproduce this. @scofield-hello Can you confirm whether my code and gif below is what you are doing when you see the crash?

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Demo Home Page'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Form(
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center,
                  mainAxisSize: MainAxisSize.min,
                  children: <Widget>[
                    TextFormField(
                        decoration: const InputDecoration(
                          hintText: "设置您的密码",
                          labelText: "密码",
                        ),
                        maxLength: 16,
                        obscureText: true,
                        keyboardType: TextInputType.text,
                        focusNode: FocusNode(),
                        textInputAction: TextInputAction.next,
                        validator: (value) {
                          return null;
                        },
                        onFieldSubmitted: (value) {
                        }),
                    TextFormField(
                        decoration: const InputDecoration(
                          hintText: "再次确认您的密码",
                          labelText: "确认密码",
                        ),
                        maxLength: 16,
                        obscureText: true,
                        focusNode: FocusNode(),
                        keyboardType: TextInputType.text,
                        textInputAction: TextInputAction.done,
                        validator: (value) {
                          return null;
                        },
                        onFieldSubmitted: (value) {
                          FocusScope.of(context).unfocus();
                        }),
                    Padding(
                        padding: EdgeInsets.only(top: 5.0),
                        child: FlatButton(child: Text("下一步"), onPressed: () {}),
                    ),
                  ],
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

I have found that changing the keyboard language can make a difference. Maybe change to a chinese keyboard?

I tested it again, it only happened when i use TextEditingController with a defalt text.

  final TextEditingController passwordController = TextEditingController(text: "123456");
  
  Widget build(BuildContext context) {
   ......
  }

@justinmc you can try TextEditingController with a default text

My app also crashed with this error message

I found this error when using voice-to-text by google keyboard.

I tried with a controller and default text and couldn't reproduce it. I also tried a Chinese keyboard, but it doesn't seem to allow Chinese characters to be typed in the field anyway.

I was able to reproduce it using voice typing though! In a plain TextField(), I entered "hello world" with my voice, then deleted a few characters with the keyboard, and got this crash:

@justinmc you can try the code bellow, thank you for helping me.

class PwdInitializeForm extends StatefulWidget {
  PwdInitializeForm({Key key, this.onSubmit}) : super(key: key);

@justinmc Only crashes when running for the first time, but hot restart works well .
try the code bellow: flutter run -> crash

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Demo Home Page'),
        ),
        body: Center(
          child: TextFormField(
              controller: TextEditingController(text: 'aaaa'),
              decoration: const InputDecoration(
                hintText: "设置您的密码",
                labelText: "密码",
              ),
              maxLength: 16,
              obscureText: true,
              keyboardType: TextInputType.text,
              focusNode: FocusNode(),
              textInputAction: TextInputAction.next,
              validator: (value) {
                return null;
              },
              onFieldSubmitted: (value) {}),
        ),
      ),
    );
  }
}

Can anyone reproduce this on the master channel? I can't reproduce it using the code samples above. The voice typing crash isn't even happening anymore...

@justinmc I am sure it still happens on the master channel，I can use the above example code to reproduce every time. Please note that it only crashes when you flutter run.

1. using the code samples above
2. flutter run (not hot restart)
3. delete the password and it will crash
   I don't know if it will happen on the Android emulator, but it will happen on my real Android device.

@scofield-hello I did not use Sogou Input keyboard, but it also crashed. 我用的是华为自带的键盘输入法。
你能不能试试我上面的代码，然后按照我写的步骤尝试一下，看看会不会闪退。只有flutter run会闪退。

@pakyo-pan 我在两台手机上测试了，一台是VIVO手机, 用的VIVO输入法，不用flutter run也会闪退。
在小米8上，默认使用小米安全键盘，没有闪退

@justinmc I have tested it on two devices with two different Input Keyboard app, one crashed and the other one was just fine. can you try some different kind of Input Keyboard app ?

I was just able to reproduce the voice typing crash on a Samsung Galaxy S6 on master. I said some words, pressed the "X" button to close voice typing and return to the original keyboard, and then I pressed delete twice. Seems to consistently crash. Also to note, the delete key on the voice typing keyboard doesn't seem to work at all, which may be related.

I still couldn't reproduce the crash just by deleting the existing text or typing and deleting. I tried the default Chinese keyboard on the S6, and I made sure I directly ran "flutter run" rather than hot reloading. I will try again on a Huawei phone later.

@GaryQian Do you have any idea where to start based on the stack trace above? It's coming from Android (SpannableStringBuilder.java) and only mentions one line from Flutter (io.flutter.plugin.editing.InputConnectionAdaptor.sendKeyEvent(InputConnectionAdaptor.java:152)).

flutter/engine#8956 this PR deals with handling of backspace on Android. It may be a good place to start looking. I do remember that this code path was only triggered for certain keyboards (gboard chinese used this code path, not gboard english). This issue may be relevant too: #23496

Thank you for the pointers!

I also had the same problem, and only had 8.1 Android on the Millet phone.
Keyboard defaults to millet safety keyboard
My operation step is to input the user name, click the password, click the user name to delete, delete two characters and start flashing back.
I found no flicker without using millet safety keyboard
Gif graphs are a little bit more likely to take some time to wait

any solution here?

flutter/engine#9322 This may be part of the solution.

i downgrade my flutter version from 1.6.3 beta to 1.2.1 stable, issue solved.

Tagging this as a regression since the old version fixed this.

I tried it on a Huawei P8 and was not able to repro, but we are currently working on obtaining a more complete suite of test Huawei and Xiaomi devices in order to better deal with issues like this.

I believe this can indeed happen, but it seems it is on a very specific subset of devices and configurations. I will try to figure out what those conditions are. In the meantime, if you have any additional information on what devices/environments this repros on, it would be very helpful!

@GaryQian Thank you for helping us. My client told me the problem still exists on Huawei honour V8, it may help you to solve the problem.

We are currently sourcing the appropriate devices needed to properly reproduce this. We have tried on a few modern Huawei flagships, but did not see this crash. We are working on obtaining older Huawei devices with Chinese firmware.

Do you think you could check if this crash happens when obscureText is set to false? This can help me narrow it down so that I can fix this without a full repro.

@GaryQian This crash does not happen when obscureText is set to false.

is there any progress?

I tried on XiaoMi 5s

This exception occurs on my login page with two TextFormFields, ObscureText of first is set to false, the other obscureText is set to true. I filled the two TextFormFields one by one, then switched to first one and pressed on delete button, crashed!!!

Thanks for the additional data points, I should be able to repro this (hopefully) by tomorrow as we have acquired the exact devices and configurations mentioned here.

I suspect this is caused by certain glyphs being condensed into one single obscured "dot", making the underlying text buffer longer than the actual displayed text.

I have been able to repro on a Huawei Nova 4 VCE-AL00

I'm also meet the problem on android device.
I'm use the new latest version of stable.

flutter/engine#9734 The problem seems to be deeper within Huawei's fork of Android. The PR above should prevent crashing, but introduces a much less serious bug where deletion will delete more characters than expected when the text is longer than the initial contents.

I upgrade version to 1.7.8+hotfix.3. And run will crash.

It seems to be caused by the "security keyboard".
It can also be seen through my recording screen: In the state of the security keyboard, it is a black screen, and even the recording screen of the system can not get the state of the current screen.
So I guess maybe flutter can't get the current state or keyboard focus monitor, which causes the text length of flutter to get the input box is incorrect.

And I not use the security keyboard, no crash.

When this bug is fixed, can it be merged into version 1.7? @GaryQian

Some keyboards will trigger the engine's version of backspace handling. Turns out it is not unique to Huawei devices, but the fix above should prevent this particular crash in all devices.

1.7 is already released. I can see if it can be hotfixed, but it is unlikely to make it into the 1.7 stable release, especially since this is an engine change.

FYI, I encountered this bug on the Pixel 3a when switching to the Google Japanese Input keyboard and then either pressing space or backspace, but it went away after running flutter upgrade today (beta channel).

version error ,use 1.5,The latest 1.7 will report this error.

The fix has landed. Please check the master and dev channels to get the fix. Closing this issue. Please let me know if anyone is still experiencing the crash and I will be happy to repoen.

There is a new known bug where backspace will delete too many characters, but we should track that separately. #36007

This issue has been patched into the latest stable release, which is baking in the beta channel presently. We anticipate pushing a release with this patched fix to the stable channel later this week.
