请说明如何操作会遇到上述问题

项目是混合开发的，就是首页有三个tab，每个tab里面都是一个继承FlutterBoostFragment后的Fragment，然后通过 meFlutterFragment =
FlutterBoostFragment.CachedEngineFragmentBuilder(MeFlutterFragment::class.java)
.url("me_page")
.urlParams(params)
.build()

这种方式去启动flutter里面的界面。

但现在发现在一些自动填充功能的手机上，会导致填充崩溃，java.lang.NullPointerException: Attempt to invoke virtual method 'void io.flutter.plugin.editing.TextInputPlugin.onProvideAutofillVirtualStructure(android.view.ViewStructure, int)' on a null object reference

查看代码发现FlutterView里面有这个
@OverRide
public void onProvideAutofillVirtualStructure(@nonnull ViewStructure structure, int flags) {
super.onProvideAutofillVirtualStructure(structure, flags);
textInputPlugin.onProvideAutofillVirtualStructure(structure, flags);
}

这里可能会有一些启动的时机不对导致textInputPlugin为空报错

请问有没有比较好的方法能够解决这个问题。

在下面填入关键复现代码

class MeFlutterFragment : FlutterBoostFragment() {
    private val uniqueId: String? = null

    override fun onResume() {
        super.onResume()
        CacheManager.getInstance().calcCacheSize(true)
        setStatusBarColor()
    }

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val containerManager = FlutterContainerManager.instance()
        val top = containerManager.topContainer
        if(top!=null && top !is MeFlutterFragment){
            top.detachFromEngineIfNeeded()
        }
        return super.onCreateView(inflater, container, savedInstanceState)
    }


  meFlutterFragment =
            FlutterBoostFragment.CachedEngineFragmentBuilder(MeFlutterFragment::class.java)
                .url("me_page")
                .urlParams(params)
                .build()

flutterboost的版本是5.0.2

复现的平台

Android

Flutter SDK版本

3.22.2

FlutterBoost版本

5.0.2

是否延迟初始化FlutterBoost

No
