How to generate dynamic object

Hello,
i tried so far:

Code:

Component.onCompleted: {var newObject = Qt.createQmlObject('
                                                                import QtQuick 1.0;
 
 
                                                                Rectangle {
 
                                                                x:20; y:20;
                                                                width: 20; height: 20;
                                                                color: "blue";
 
                                                                }',
                                          container, "dynamicSnippet1");}

but i am getting Syntax Error : Parse Error.

Where am i wrong?
Thanks

i found the solution. i must not to split the lines, the string parameter must be one line or must be concat with + operator.
