Why is flutter showing multiple past errors on run?

Question

I recently updated flutter and now a problem seems to occur when I run the project using flutter run.

Indeed, a list of all the errors I had previously is being shown on the screen (which is obviously getting bigger and bigger over time). I tried to recreate a new project and the problem still occurred. Here's an exemple: I didn't include my assets in the pubsec.yml file which obviously triggered an error at first. And now, while it's solved, it still shows on the log. Here it is:

This problem occurred using the emulator first, then I switched to test it on my phone and it just cleared the log but the problem persisted, it just started all over. So, I tried to clear app data and uninstall the app from the emulator and it didn't solve a thing and this time it didn't started from scratch.

I'm a bit lost and this is starting to be a bit annoying over time to have this massive log of errors in which I don't know which one is real and which is not.

Thanks in advance for your help!

                Container(
                  width: 230,
                  height: 150,
                  child: Image.asset("assets/images/image.png"),
                ),
