    Looks like you are in release mode. There's no observatory in release mode.

    According to this doc https://flutter.io/debugging/

    If you use Observatory for profiling, make sure to run your application in release mode, by passing --no-checked to the flutter run command.

    Does that mean it's available in release mode ? I tried it even by disabling the checked mode.

    I think that information is outdated. It predates the debug/profile/release split. /cc @Hixie

    Yeah that should be --profile. We'll have to update that page.

    Would be nice if we can make it available as a run option in the Intellij ide.
