Requests a line of text from the user. On platforms that have only a virtual keyboard, this
will display a text entry interface, obtain the line of text, and dismiss the text entry
interface when finished.

@param textType the expected type of text. On mobile devices this hint may be used to display a
keyboard customized to the particular type of text.
@param label a label to display over the text entry interface, may be null.
@param initialValue the initial value to display in the text input field, may be null.

@return a future which provides the text when it becomes available. If the user cancels the
text entry process, null is supplied. Otherwise the entered text is supplied.
