How to make Flex Spark Label to be auto resized?

I'm creating the Label component like this

var label:Label = new Label();
label.text = "some text";
label.styleName = "someStyle";
addChild(label);

But it stay invisible until I explicit set the width and height.
How can I make the label to be auto resized according to it's text?

I've also noticed the above answer doesn't seem to work with spark components. This does however work for me.

label.width = label.measuredWidth; label.height = label.measuredHeight;

I've found the answer to my question here
The solution is to call a measureText() function for the label

var lineMetrics:TextLineMetrics = label.measureText(label.text);
label.width = lineMetrics.width;
label.height = lineMetrics.height;

You should be able to use label.percentWidth = 100; to allow the label to automatically grow with the text. If you want it to stay on a single line, you'll also want to set the maxDisplayedLines = 1; property as well.

You may also want to use addElement(label) instead of addChild(label).
