Improving retaining path identifier in Diff view

Retaining paths are currently identified by the last few nodes as shown in the screenshot below. The identifiers often include classes internal to Dart and Flutter, which the app developer is likely to be unfamiliar with. Thus, it's unclear the information in such identifiers actually providing any value to the majority of users.


It might not hurt to identify different retaining paths simply by number such as Path 1, Path 2, Path 3, etc. The detailed path information is available on the right hand side of the table once the user selects one of them. Thoughts?

从 DevTools 的 Diff 视图开始，检查 retaining path 标识符是如何生成并显示在表格中的。将表格的选择行为与右侧显示的详细路径信息进行比较。当不同路径具有清晰的标识符，并且选择某一路径后仍会显示其详细路径时，即表示完成。
