visual-studio - 一个 RenderFlex 在底部溢出了 45 个像素。扑

问题描述

当我将屏幕切换到登录屏幕然后在 TextField 中键入时，我遇到了 RenderFlex 溢出问题。一旦我键入并垂直滚动，我就会返回板载屏幕，就会出现错误。似乎当我用“SingleChildScrollView”包裹“Column”时，问题就出现了。我已将代码添加到以下问题。

flutter: The following assertion was thrown during layout:
flutter: A RenderFlex overflowed by 45 pixels on the bottom.
flutter:
flutter: The relevant error-causing widget was:
flutter:   Column file:lib/screens/splash/components/splash_content.dart:17:12
flutter:
flutter: The overflowing RenderFlex has an orientation of Axis.vertical.
flutter: The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
flutter: black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
flutter: Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
flutter: RenderFlex to fit within the available space instead of being sized to their natural size.
flutter: This is considered an error condition because it indicates that there is content that cannot be
flutter: seen. If the content is legitimately bigger than the available space, consider clipping it with a
flutter: ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
flutter: like a ListView.
flutter: The specific RenderFlex in question is: RenderFlex#a88be OVERFLOWING:
flutter:   needs compositing
flutter:   creator: Column ← SplashContent ← RepaintBoundary ← IndexedSemantics ←
flutter:     NotificationListener<KeepAliveNotification> ← KeepAlive ← AutomaticKeepAlive ← KeyedSubtree ←
flutter:     _SliverFillViewportRenderObjectWidget ← _SliverFractionalPadding ← SliverFillViewport ← Viewport ←
flutter:     ⋯
flutter:   parentData: <none> (can use size)
flutter:   constraints: BoxConstraints(w=428.0, h=319.8)
flutter:   size: Size(428.0, 319.8)
flutter:   direction: vertical
flutter:   mainAxisAlignment: start
flutter:   mainAxisSize: max
flutter:   crossAxisAlignment: center
flutter:   verticalDirection: down
