Describe the bug Three questions:

1. Click twice to return to the parent page, when the partsInRootNavigator is set to true.

https://github.com/see/flutter_github/blob/be026fdcad064aee986faf53eb076692e4758a5c/lib/app/routes/app_pages.dart#L66

2. When the button is clicked to return, the content displayed on the two pages is different. Personal guess, the return value of the following code is empty.

https://github.com/see/flutter_github/blob/be026fdcad064aee986faf53eb076692e4758a5c/lib/app/modules/trending_detail/bindings/trending_detail_binding.dart#L10

3. The title of the trending page is not displayed. When switching to this page from another page, it is displayed normally.
