[PPT] Error creating the CFMessagePort needed to communicate with PPT.

[martin-robert-fink]

On iOS get the error: [PPT] Error creating the CFMessagePort needed to communicate with PPT. when using FlutterEmailSender.send(email).

The email window comes up as expected. If I send or cancel the email, then I get the following error stream:

is there something I'm doing wrong? Thanks!

[LIMMIHEE]

I'm having the same problem, did you solve it?

[martin-robert-fink]

Nope. Just ignoring the error.

[espbee]

@martin-robert-fink have you had any issues? is your app live? i don't get the follow up errors, sending and canceling are fine. but it's disconcerting anyway.

[martin-robert-fink]

No follow up. Here's a video of the app (if you're interested): FPGA View.

I'm rewriting large chunks of the app. I'm changing state management from GetX to Bloc and I'm making the VCD parser multi-threaded (as well as the waveform painter). This version was written/optimized primarily for the iPad. Users really wanted a web version, so that's the motivation. Doing threads (Isolates on native and web workers on web) is a bit of a challenge in a multi-platform environment. That's what I'm working through now.

[espbee]

@martin-robert-fink indeed, good luck with the threading. So you haven't gone through the Apple store yet, or any such ?

[martin-robert-fink]

Only through the beta (now expired). No issues with the App Store at least for TestFlight.
