Explain Android Studio console output format and how configure to show date/time in each line?

Question

I'm new to Flutter and it would be really nice to know when a line of trace was emitted.

A simple print statement in a Flutter class like this:

print("hello, console logging");

outputs this in the Console / "4. Run" bottom-tab:

I/flutter ( 6731): hello, console logging

Three questions:

1. What does "I/flutter" mean?
2. What does "6731" mean?
3. Is it possible to configure something to add a timestamp to each line to show "HH:MM?"

I've researched this for about an hour and I can't find any answers.

Answer 1

I/flutter: It means message logging of 'Information' kind. flutter is the tag for the log. More info https://developer.android.com/reference/android/util/Log

In the android studio, you can find the method Log.i() which accepts a TAG and a message to log. Example. Log.i("flutter", "Some message here..");

To print the time of the log you can append TimeOfDay.now().toString() with your print message, as print("hello, console logging. Time: " + TimeOfDay.now().toString());
