Shows the virtual keyboard if the platform has one.
The existing_text parameter is useful for implementing your own LineEdit or TextEdit, as it tells the virtual keyboard what text has already been typed (the virtual keyboard uses it for auto-correct and predictions).
The multiline parameter needs to be set to true to be able to enter multiple lines of text, as in TextEdit.
Note: This method is implemented on Android, iOS and UWP.
