def get_text(self):
text = self.attr('<STR_LIT:text>')<EOL>return text<EOL>
Get the text attribute of the UI element. Return None if no such attribute. Similar to :py:meth:`.attr('text')
<poco.proxy.UIObjectProxy.attr>`.

Returns:
    :obj:`str`: None if the UI element does not have the text element, otherwise the utf-8 encoded text value.
    In both py2 and py3, the return value type will be :obj:`str`.
