Unable to open 'lib object_patch.dart': cannot read property of undefined and TypeErrors

[rhysduggan5]

In a program that was recently working perfectly fine, upon running the app as normal the launch screen would show, then it would error and give me this into the console:

And yet the last time I ran it all that was different was that there weren't images within the runner of the application, to give the launch screen an image. Any ideas why this is happening?

I just installed dart onto this machine and am using visual studio code with all the most up to date version installed.

Are you using VS Code insiders (1.31)? This looks like a VS Code bug at a glance, and their issue tracker seems to have a lot of "cannot read property 'x' of undefined" errors in it:

If it is Insiders, I think it is worth raising there (and confirming it doesn't happen in stable).

I get a different issue in insiders :(

Cannot read property 'adapter' of undefined

I've opened an issue about that one!

I am currently using v1.24.1, not insiders. After more tests it seems to have nothing to do with adding a launch screen image, as removing it didn't remove the error. It probably is a vs code bug. I could try running it in android studio to see if it makes any difference, to narrow down the error.

Ah, ok! The error is occurring inside VS Code code, so it definitely won't repro in Android Studio.

I would definitely open an issue in the VS Code repo with the screenshot (or maybe test it in Insiders first, it's possible it's gone). Even if we have a bug that's causing it, I don't think VS Code should fail like that. They may be able to provide tips to debug.

(If you do, please paste the link back here so I can help investigate if required)

Yep, it seems to have been fixed in VS insiders, so no problems!

Great! 👍
