调研方向
该 issue 未指定源文件或测试；从 ctx.triggered_id 的 Python 定义和 callback 上下文类型开始。使用列出的 Dash 版本复现通过模式匹配进行访问的情况，然后验证静态分析允许字典访问，同时无触发器情况仍得到表示。
由索引模型根据 Issue 内容生成。
描述
Describe your context
Please provide us your environment, so we can easily reproduce the issue.
dash 4.4.1
dash_ag_grid 35.3.0
dash-extensions 2.0.6
dash-iconify 0.1.2
dash_mantine_components 2.8.0
Describe the bug
I am defining multiple dynamic components and set their id like this:
id={"type": "entry", "index": id},
where the value of "index" gets changed depending on the component.
Now, when I want to use the id in a pattern-matching callback, I need to get the value of "index"to search a sqlite database. When I use
ctx.triggered_id.get("index"))
however, VS Code produces an error and says: ""get" is no known attribute of "None"". The call however correctly returns the value of "index"
The same problem happens with ctx.triggered_id["index"], although the error then says: "None" object is not subscriptable.
FYI: I translated the error messages from German to English. They could be slightly inaccurate, though their meaning should be correct
Expected behavior
I would expect it to see a dict as a possible type of triggered_id, so that there is no error shown.
