java.lang.NullPointerException: Attempt to invoke virtual method 'void io.flutter.plugin.editing.TextInputPlugin.onProvideAutofillVirtualStructure(android.view.ViewStructure, int)' on a null object reference #149792
Description
Steps to reproduce
1、update flutter version from 3.3.9 to 3.16.9
2、Open the phone settings and turn on the application password book function
3、create a viewpage fragment, one is native fragment and has edit, other is flutter fragment and init
then,
When you click on the edit box of the native fragment, it will inevitably collapse and appear.
Expected results
click normal
Actual results
java.lang.NullPointerException: Attempt to invoke virtual method 'void io.flutter.plugin.editing.TextInputPlugin.onProvideAutofillVirtualStructure(android.view.ViewStructure, int)' on a null object reference

FlutterView method：
public void onProvideAutofillVirtualStructure(@nonnull ViewStructure structure, int flags) {
super.onProvideAutofillVirtualStructure(structure, flags);
this.textInputPlugin.onProvideAutofillVirtualStructure(structure, flags);
}
This method adds try-catch, which can be added, but it is difficult and there is no other way to deal with this problem.

Hi @marchlqq
What is
passwork bookfunction? Which Android device are you using? (OS, model)Also, the goal of this Github repo is not to assist in personal code or the whole package/plugin project but to improve Flutter framework reporting bugs or feature requests. Your sample code (mtp_test_demo.zip) is a package project that contains the complex implementation and also uses 3rd packages.
For the issue to be workable, it needs to be reproducible with a completed and minimal reproducible code sample that doesn’t include 3rd party plugins or complex production code. Please provide such a sample and please provide output of
flutter doctor -vas well.marchlqq commentedon Jun 6, 2024

A complete and minimal reproducible code example is not available yet.

Please try to provide a minimal sample code so that we can look into it easier. Thanks!

The problem occurs when:
I clicked on the initial interface and the input method popped up, but because the system password book function was turned on, a rough code was run, but the textInputPlugin was not initialized, so it crashed.
I want to add try-catch to this method body.

To help us look at the issue more easily, please narrow the issue down by removing the usage of 3rd party plugins/packages one by one, unrelated/unaffected code, and isolating the issue into a minimal sample code. And please share it here when you have such an example. Thanks!

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
