Dart private variable "unused"

Both _pegHoleImage and _isPeg are private class variables yet _isPeg is seen by other functions but _pegHoleImage is not. What is the difference? I get the error message in Android studio that _pegHoleImage is not used, but I use it in the setImage() function. Thanks in advance for your help.

class PegHole {

    PegHole({@required isPeg}) {
        _isPeg = isPeg;
        setImage();
    }

    Image _pegHoleImage;
    bool  _isPeg;

    toggle() {
        _isPeg = !_isPeg;
        setImage();
    }

    setImage() {
        _pegHoleImage = _isPeg ? Image.asset(kPEG_FILENAME) : Image.asset(kHOLE_FILENAME);
    }

    bool getPegStatus() {
        return _isPeg;
    }
}

It's because you're setting it but never using it.

Add this getter and it goes away.

Image get pegHoleImage => _pegHoleImage;
