Issue with POINTERDOUBLETAP and Flutter

Questions
1

Hi folks,

At Smplrspace, we have a Babylon-based 3D viewer that other software companies integrate into their applications. It’s been used in prod for 3 years and today we’ve got an issue reported for the first-time where the POINTERDOUBLETAP event doesn’t seem to work on a mobile app that’s built with Flutter. The mobile web version (on React) works well, and the Flutter-based mobile app is generally fine, except for POINTERDOUBLETAP that doesn’t seem to respond.

Has anyone come across this problem? Any thoughts on where this might come from? As we’re not Flutter (or mobile) devs ourselves, we’re a bit at a loss here, and I was hoping that this might light a bulb :bulb: in someone else’s head here, and we could get some pointers.

In case it helps, they use the Flutter sdk 3.29.0, release date 12/2/2025.

Thanks,
Thibaut

Hi @tibotiber,
I’m also not familiar with Flutter, sorry, this doesn’t spark a light bulb. Is it possible to get a repro from your partner? I wonder if Flutter is intercepting any of the pointer events, but without a repro I can’t test that hypothesis.

Thanks!

I’ll see if they’re able to provide that. Thanks for the response.
