Touch gestures do not work

[chickenblood]

Gestures are never recognized in Dartpad.

Steps to reproduce problem

See normal sample app. Try tapping the + button to increment the counter. Clicking with a mouse works, but if you use the app on an iPad in Safari or Chrome, taps are not detected.

This is bad, because I am prototyping home widgets in Dartpad and they are specifically optimized for tablet and gestural interaction. As such, the designer cannot see how they "feel" unless they use the mouse on the desktop (or attach a keyboard to the iPad), which is less than ideal.

DartPad's output

Did DartPad print anything to the console pane? If so, paste it below:

If you were running Flutter code, you can also paste an image of the Flutter output directly into this bug report.

We have a few issues involving iPad use (#1417, for example), and just haven't had the engineering bandwidth to investigate them. Your concern is totally valid, and thanks for filing an issue. I can't say for certain when we'll have time to get this on the roadmap, though.
