          # enter text then tap window to hide the keyboard.
=begin
Find the top left corner of the keyboard and move up 10 pixels (origin.y - 10)
now swipe down until the end of the window - 10 pixels.
-10 to ensure we're not going outside the window bounds.

Swiping inside the keyboard will not dismiss it.

var startY = au.mainApp().keyboard().rect().origin.y - 10;
var endY = au.mainWindow().rect().size.height - 10;
au.flickApp(0, startY, 0, endY);

The above logic has been accepted as part of appium's au.hideKeyboard
https://github.com/appium/appium-uiauto/blob/dbeb4eedbdea2104751a0d547ac9b2894e0dc567/uiauto/appium/app.js#L902

If the 'Done' key exists then that should be pressed to dismiss the keyboard
because swiping to dismiss works only if such key doesn't exist.
