"Unable to parse platform message" when running on Linux about flutter-desktop-embedding HOT 5 CLOSED

Terminal output displays this

What exactly are you doing when you get this message? You mention the file chooser; is this when you close the native dialog after selecting a file?

no files are saved or loaded

They aren't supposed to be, it just shows a snackbar with the results of the dialog. Are you not seeing that?

As soon as I launch the app.

It's working as intended

I'm not able to repro on macOS or Linux. The logging indicates that we're receiving an (apparently invalid, or at least not JSON codec) call to the method handler on startup from the Flutter side, which is unexpected. I'm assuming you haven't edited the example app since you didn't mention local changes?

What's your Flutter tree hash?

I couldn't reproduce it again

I just hit this on macOS. I don't know for sure if your case was the same, but there are cases where Flutter will send things on the flutter/accessibility channel. That doesn't use the JSON codec, so will cause this message.

In the short term I'll drop that silently (and improve the error message to include the channel in case something else comes up in the future).
