How can I flip the left and right sides of the text(label)?

MIT App Inventor Help

I am developing an app for AR(augmented reality).

The left and right screens of the app are flipped when displayed on the AR screen.

Thus, I want to flip the text(label).

Would you let me know how I can change the left and right sides of the text?
flip

Can be done with a backward font, the MyFonts extension and a text reverse block

Although there is no "SetRotationY" in my MyFonts extension version, I solved the problem using the MyFonts extension. Thank you.

Correct, you use the LabelPlus extension for that

If you want to avoid extensions, it might be possible to do this using a WebViewer and the SVG graphics scale transform on your text, setting the x scale to -1.

I unfortunately have no working example for you.

Using the html canvas

<!DOCTYPE HTML>
<html>
<head>
    <style>
        #myCanvas {
            border: 1px solid #bbb;
        }
    </style>
</head>
<body>
    <canvas id="myCanvas" width="578" height="200"></canvas>
    <script>
        var canvas = document.getElementById('myCanvas');
        var context = canvas.getContext('2d');
        // scale context
        function scaleText() {
            context.font = "30px Arial";
            context.fillText("Hello World", 10, 50);
            context.scale(-1, 1);
            context.fillText("Hello World", -165, 100);  // << x,y positioning is a fiddle....
        }
        scaleText();
    </script>
</body>
</html>
