══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during performLayout():
BoxConstraints has both a negative minimum width and a negative minimum height.
These invalid constraints were provided to RenderSemanticsGestureHandler's layout() function by the
following function, which probably computed the invalid constraints in question:
_layoutChild (package:flutter_staggered_grid_view/src/rendering/staggered_grid.dart:470:9)
The offending constraints were:
BoxConstraints(w=-3.0, h=-3.0; NOT NORMALIZED)
The relevant error-causing widget was:
StaggeredGrid
StaggeredGrid:file:///Users/ying/work/frontend-app/lib/modules/home/views/lobby_view.dart:37:36
