当我尝试在TextField中键入时，Flutter避免扩展布局

Question

在扑通实现的简单布局中，我有一个简单的形式，它是父小部件的子代。在这种情况下，当我尝试键入TextField的页面时，将页面大小调整为最小屏幕大小，而我想避免这种情况

resizeToAvoidBottomPadding: false,无效

The specific RenderFlex in question is: RenderFlex#864a2 relayoutBoundary=up2 OVERFLOWING:
  needs compositing
  creator: Column ← DecoratedBox ← Container ← Directionality ← MediaQuery ←
    LayoutId-[<_ScaffoldSlot.body>] ← CustomMultiChildLayout ← AnimatedBuilder ← DefaultTextStyle ←
    AnimatedDefaultTextStyle ← _InkFeatures-[GlobalKey#9a5c5 ink renderer] ←
    NotificationListener<LayoutChangedNotification> ← ⋯
  parentData: <none> (can use size)
  constraints: BoxConstraints(0.0<=w<=298.0, 0.0<=h<=123.1)
  size: Size(298.0, 123.1)
  direction: vertical
  mainAxisAlignment: start
  mainAxisSize: max
  crossAxisAlignment: start
  textDirection: rtl
  verticalDirection: down

我的代码：

return Form(
  key: _formKey,
  child: Container(
    margin: EdgeInsets.fromLTRB(12.0, 5.0, 12.0, 0.0),
