ios_platform_view_test
A simple app contains:
- A home with a button that pushes a new page into the scene.
- A page contains a platform view, a button, and a text.
- Press the button will update the text.
We use this app to test platform views in general such as platform view creation, destruction, and thread merging(iOS only).
