java.lang.NullPointerException: Attempt to invoke virtual method 'void io.flutter.plugin.editing.TextInputPlugin.onProvideAutofillVirtualStructure(android.view.ViewStructure, int)' on a null object reference

### 请描述遇到的问题，以及您所期望的正确的结果

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.

crash log：
java.lang.NullPointerException: Attempt to invoke virtual method 'void io.flutter.plugin.editing.TextInputPlugin.onProvideAutofillVirtualStructure(android.view.ViewStructure, int)' on a null object reference

一定要开启密码本：

最好是pad或者折叠屏手机：

### 在下面填入关键复现代码

demo:
[mtp_test_demo.zip](https://github.com/user-attachments/files/15605037/mtp_test_demo.zip)

### 复现的平台

Both

### Flutter SDK版本

3.16.9

### FlutterBoost版本

5.0.1

### 是否延迟初始化FlutterBoost

No

### 解决方案

Start by reproducing the crash with Flutter SDK 3.16.9 and FlutterBoost 5.0.1 using the provided demo, an Android pad or foldable device, and the password-book setting enabled. Inspect FlutterView.java around line 1525 and the TextInputPlugin.onProvideAutofillVirtualStructure call; done means the native edit box no longer crashes when the Flutter fragment is present.
