Flutter not printing colors

[dash-dash-force]

Hi guys,

I'm using Fimber for a project, and wanted to have colored output. I used the code below. However, I still get white-only output. I'm using iTerm2 on MacOS Catelina (10.15.3).

final tree = DebugTree(useColors: true);
Fimber.plantTree(tree);

Any idea?

Hi, thank you for filing issue. @dash-dash-force Do you have any unexpected characters? Does other terminal (original MacOS) displays colors?

[dash-dash-force]

Hey @magillus, thanks for your response. Both do not display colors as output of the app. I do see unexpected characters however, e.g. this output:

flutter: \^[[32m2020-04-02T09:39:55.414506

The \^[[32m wasn't there normally.

hmm.. thanks, it seems like the terminal app doesn't support this or the text encoding isn't picked up/setup. I will try to investigate this, I have access to Mac to try this out.

Awesome @magillus! Hope you'll find something :).

I can't reproduce it:

Left is iTerm on right is MacOs terminal - both render colors correctly.

@magillus too bad, but thanks a lot for checking! Last question: which macOS version were you on?

[magillus]

I don't remember from top of my head - will check later. git clone repo and run this test yourself: dart test/colorize_test.dart

@magillus it works there! Weird .... 🤔

If you could create sample CLI app and try it again. But not sure what would be different then the test.

Closing the issue, if you still run into this on CLI in terminal please submit reproducible example and reopen issue.

Thank you.
