Flutter-intellij: Clear console on hot-restart

[zoechi]

Steps to Reproduce

• Run a Flutter app in IntelliJ
• hot-restart

The console keeps the log from the previous run and it is difficult to see what log is from the current run.

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel dev, v0.3.5, on Mac OS X 10.13.4 17E202, locale en-AT)
[✓] Android toolchain - develop for Android devices (Android SDK 27.0.3)

[✓] Android Studio (version 3.1)
[✓] IntelliJ IDEA Ultimate Edition (version 2018.1.2)
[✓] Connected devices (2 available)

If others want the console content to persist adding settings to enable/disable might make sense.

Thanks for the feedback!

As it happens, we'll be looking at an improved logging experience in the coming weeks so this is especially timely. 👍

I opened up an issue for brainstorming (#2200); please feel free to chime in there!

@zoechi, can you provide a bit more details on how to repro? I'm trying to locally, and do see us clearing the console for both hot reload and hot restart.

[zoechi]

@devoncarew it's a feature request.
I want the console be cleared in hot reload the same as with full restart or hot restart.

Especially when working on UI errors are often printed dozens of times
and then it's hard to find which errors were before or after the last code changes.

[devoncarew]

I do see the console being cleared both for hot reloads and for hot restarts (full restarts). Is this not what you're seeing?

[zoechi]

No, hot reload just adds to the previous output.

same with hot restart

Only a full restart clears the console
(sorry if I caused confusion - in my previous comment I said that hot restart also clears the console, which is not the case)

Also with flutter run and r the console is not cleared.

[devoncarew]

Ah, you have the verbose logging option on. We don't clear the console if that setting is enabled - we assume that people want the full history of the output for debugging reasons.

[zoechi]

Thanks! After disabling verbose logging the console is cleared.
Wasn't aware of that connection.

[zoechi]

Was a long time ago that I enabled verbose logging and forgot about it.
It's much better now ;-)

hi, how to "disabling verbose logging"?

[zjw1918]

After updated to flutter 12 stable (1.12.13+hotfix.5), the previous full history logs will be shown in the console every time when i run "flutter run".

ps:
flutter doctor -v

@zjw1918, can you file a new issue for this? I think this should be filed at the flutter/flutter repo, as this might be due to changes in how we scrape flutter logs.

[zjw1918]

Yea. Just realized the repo is intellij. Thanks.

@zoechi From where we disable verbose option ?
