{reactlog} 生成的 r 闪亮反应日志图形中的 "Theme Counter" 是什么?

What is "Theme Counter" in r shiny reactive log graphics generated by {reactlog}?

reactlog::reactlog_enable()函数生成一个名为“主题计数器”的输入节点。有人知道它代表什么以及记录在哪里吗?

这是 reactiveVal 定义的 here which is used to create a reactive dependencysetCurrentTheme 被调用以进行相应的闪亮会话时。

setCurrentTheme说明如下:

  # This function does three things: (1) sets theme as the current
  # bootstrapTheme, (2) re-executes any registered theme dependencies, and
  # (3) sends the resulting dependencies to the client.
