[Engine][iOS] Cancel animation when recieved UIKeyboardWillHideNotification with duration 0.0 (#164884)
fix https://github.com/flutter/flutter/issues/112281

The event log output shows that `UIKeyboardWillHideNotification` occurs
immediately after `UIKeyboardWillShowNotification`. However, the
animation is not cancelled in response to
`UIKeyboardWillHideNotification`.

This PR adds animation cancellation processing in response to
`UIKeyboardWillHideNotification` with duration 0.0.

Flutter Engine

Setting up the Engine development environment

See here

gclient bootstrap

Flutter engine uses gclient to manage dependencies.

If you've already cloned the flutter repository:

  1. Copy one of the engine/scripts/*.gclient to the root folder as .gclient:
    1. Googlers: copy rbe.gclient to enable faster builds with RBE
    2. Everyone else: copy standard.gclient
  2. run gclient sync from the root folder
