使用手风琴时出现kivy.lang.parser.ParserException

Question

要求：

我试图熟悉KiyvMD，预期的UI布局的第一行是一个工具栏，其后是MDAccordion，它带有两个不同的子项[MDAccordionSubItem]。下面是代码片段

问题 运行此代码时，出现错误“ kivy.lang.parser.ParserException：[文件位置]

25：标签： 26： 27：specific_text_color：1、1、1、1 28：MDAccordionItem： 29：标题：“ HOME”

消息：声明后的数据无效

我看到错误是在第27行引起的，我只是不明白为什么？在4个空格后声明第28行的内容仍然会引发相同的错误。欢迎您提供反馈意见：）
