Use a screen height ratio to determine if the keyboard is onscreen or not. This is used because Android does not provide a deterministic API to detect this.
We remove the padding when the keyboard is closed and the inset is due to the hidden navigation bar, otherwise, we apply the full keyboard inset.
Decouple PlatformViewsController from FlutterView.
Instead of getting a FlutterView instance, depend on the specific interfaces required by
PlatformViewsController (BinaryMessenger, TextureRegistry, and Context).
This allows using PlatformViewsControlling in the flutter/embedding
code.
- Switch core snapshot to Dart 2 and remove support for loading platform.dill.
- Remove support for loading script snapshots.
- Remove support for loading source.
- Remove settings and fix names to reflect the above.
- Remove support for loading the service isolate from source.
Otherwise the callbacks may be called after FlutterNativeView is destroyed and is null.
Also defensively check for whether the texture is already released in the callback because the callback may be called from another thread by a stale reference (see the comment).
This closes https://github.com/flutter/flutter/issues/20951.
The default WindowManager implementation in Android's Presentation is
delegating addView/removeView/updateViewLayout calls to the global
WindowManager.
This can result in a crash when an embedded view is trying to e.g show a
PopupWindow.
This change adds a custom WindowManager that overrides
addView (and removeView/updateViewLayout) and adds the view to the
presentation's view tree.
Note that views might keep a reference to the window manager which
might be an issue when we move a view from one virtual display to
another (due to a resize). For this reason when re-sizing we are not
creating a new window manager for the new presentation, but updating the
window manager's references to be relevant for the new presentation and
re-use it.
This allows the framework to know that a frame with the resized view is
ready and to behave deterministically to workaround the jank issue
described in flutter/flutter/19572
* Flush all embedded Android view on hot restart.
Adds an OnEngineRestarted method to PlatformView, this is currently only
implemented for Android where we need to use it for embedded views.
* review comments followup
* rename to OnPreEngineRestart, call before Clone
Instead, send them with the new unknown PointerDeviceKind.
We hit this when running `adb shell input tap` in tests which sends events with
an unknown tool type.
This also fills in a missing conversion for TOOL_TYPE_ERASER.
