_AssertionError (‘package:flutter/src/rendering/object.dart’: Failed assertion: line 2789 pos 12: ‘!_needsLayout’: Updated layout information required for RenderIndexedSemantics#dc6e5 NEEDS-LAYOUT to calculate semantics.)

它似乎来自flutter_staggered_grid_view插件：

RenderSliverVariableSizeBoxAdaptor.visitChildren (package:flutter_staggered_grid_view/src/rendering/sliver_variable_size_box_adaptor.dart:296:29)

如果您删除该插件代码并重试，看一下该问题是否会复现
