Trying to reland #140115 which I had to revert in #142889 because [it broke the tree](https://github.com/flutter/flutter/pull/140115#issuecomment-1925774719). In this PR I fixed the post-submit following tests:
Flutter UI integration tests
This project contains a collection of non-plugin-dependent UI
integration tests. The device code is in the lib/
directory, the
driver code is in the test_driver/
directory. They work together.
Normally they are run via the devicelab.
keyboard_resize
Verifies that showing and hiding the keyboard resizes the content.
routing
Verifies that flutter drive --route
works correctly.
