Same here on Mac OS with both Chrome and Safari.

I get this when I use the colour sliders on the colour selector and drag the slider passed the end of the range.

I have just built the project locally on the current beta version and i do not get any of these errors

Framework • revision 659dc8129d (4 weeks ago) • 2019-12-30 09:24:47 -0800
Engine • revision bdc9708d23
Tools • Dart 2.8.0 (build 2.8.0-dev.0.0 c547f5d933)

@rxlabz Would you be able to trigger a build of the project on a newer version of Flutter as I think this was a Flutter issue when this was in its infancy?
