  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this

你好 ，替换新的minitex.min.js后，在接入flex_color_scheme的minitex_flutter_web_test.zip demo工程中仍有问题 FloatingActionButton的icon不显示，点击显示snackBar也不显示

Although this node is not marked as needing layout, its size is not set.

A RenderBox object must have an explicit size before it can be hit-tested. Make sure that the RenderBox in question sets its size during layout.

======== Exception caught by gestures library ======================================================
The following assertion was thrown while handling a pointer data packet:
Cannot hit test a render box with no size.

The hitTest() method was called on this RenderBox: RenderParagraph#ea5c4 relayoutBoundary=up1
...  parentData: offset=Offset(0.0, 0.0) (can use size)
...  constraints: BoxConstraints(0.0<=w<=24.0, 0.0<=h<=24.0)
...  size: MISSING
...  textAlign: start
...  textDirection: ltr
...  softWrap: wrapping at box width
...  overflow: visible
...  locale: en_US
...  maxLines: unlimited
  text: TextSpan
    inherit: false
    color: Color(0xff250059)
    family: MaterialIcons
    size: 24.0
    ""
Although this node is not marked as needing layout, its size is not set.

A RenderBox object must have an explicit size before it can be hit-tested. Make sure that the RenderBox in question sets its size during layout.

When the exception was thrown, this was the stack:
