When there are no more platform views, make sure the overlay layer is hidden. When a platform view is added again, show the overlay. The show/hide allows us to avoid continually recreating and destroying the overlay surface + swapchain when a platform view slides in and out of frame. To further reduce memory usage, we could do a delayed de-allocation of the overlay layer (say after 50 frames of no platform view, destroy it). But I'm leaving this to a follow up.
This directory contains tools and resources that the Flutter team uses during the development of the framework. The tools in this directory should not be necessary for developing Flutter applications, though of course, they may be interesting if you are curious.
The tests in this directory are run in the framework_tests_misc-*
shards.
