TextField 导致“查找停用的小部件的祖先是不安全的”扑

如何解决TextField 导致“查找停用的小部件的祖先是不安全的”扑

我有一个导致以下错误的 TextField。它仅在我开始在 TextField 中输入时触发。我尝试将 Sliverappbar 或 TextField 包装在 Builder 中，但遇到了同样的错误。

======== 小部件库捕获的异常 ================================== ====================== 为 FocusManager 分派通知时抛出以下断言：查找已停用小部件的祖先是不安全的。

此时小部件的元素树的状态不再稳定。

要在其 dispose() 方法中安全地引用小部件的祖先，请通过在小部件的 didChangeDependencies() 方法中调用 DependOnInheritedWidgetofExactType() 来保存对祖先的引用。

当抛出异常时，这是堆栈： #0 Element._debugCheckStateIsActiveForAncestorLookup。（包：Flutter/src/widgets/framework.dart:3906:9） #1 Element._debugCheckStateIsActiveForAncestorLookup (package:Flutter/src/widgets/framework.dart:3920:6) #2 Element.dependOnInheritedWidgetofExactType (package:Flutter/src/widgets/framework.dart:3962:12) #3 MediaQuery.of (package:Flutter/src/widgets/media_query.dart:814:38) #4 _InkResponseState._shouldShowFocus (package:Flutter/src/material/ink_well.dart:925:44) ... FocusManager 发送通知是：FocusManager#23a1d 主要焦点：FocusNode#4875a([主要焦点]) primaryFocusCreator：EditableText- [LabeledGlobalKey＃ccd2a]←←UnmanagedRestorationScope←RepaintBoundary←_Decorator←InputDecorator←AnimatedBuilder←_PointerListener监听←←RawGestureDetector←TextSelectionGestureDetector语义←←AnimatedBuilder←IgnorePointer←_RawMouseRegion←MouseRegion的TextField←←ConstrainedBox填充←←容器ColoredBox←⋯

下面的代码。
