ListView中有时候会出现报错

[caihua]

WidgetsBinding.instance.addPostFrameCallback((call) { width = context.size.width; height = context.size.height; button = context.findRenderObject(); overlay = Overlay.of(context).context.findRenderObject(); });

═══════ Exception caught by scheduler library ═════════════════════════════════ The getter 'size' was called on null. Receiver: null Tried calling: size

这个地方进入页面后开始自动滚动则会有上面的异常抛出
