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.
Automated Flutter integration test suites
Each suite consists of either a complete Flutter app and a flutter_driver
specification that drives tests from the UI, or a native app that is meant to
integrate with Flutter for testing.
Intended for use with devicelab tests.
If you want to run a driver test locally, to debug a problem with a test, you can use this command from the appropriate subdirectory:
flutter drive -t <test> --driver <driver>
For example:
flutter drive -t lib/keyboard_resize.dart --driver test_driver/keyboard_resize_test.dart
New tests require new CI runner
Adding code to this directory will not automatically cause it to be run by any already existing ci tooling. This directory is intentinally a "choose your own adventure" piece of tooling.
