Detailed Description

A static proxy handler for a WindowManager with custom overrides.

The presentation's window manager delegates all calls to the default window manager. WindowManager::addView calls triggered by views that are attached to the virtual display are crashing (see: https://github.com/flutter/flutter/issues/20714). This was triggered when selecting text in an embedded WebView (as the selection handles are implemented as popup windows).

This static proxy overrides the addView, removeView, removeViewImmediate, and updateViewLayout methods to prevent these crashes, and forwards all other calls to the delegate.

This is an abstract class because some clients of Flutter compile the Android embedding with the Android System SDK, which has additional abstract methods that need to be overriden.
