Version

Command type

build_runner (Default)

What happened?

First time checking out this package.

Attempting to run with the following colors file (taken from the example dir)

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="white">#FFFFFF</color>
    <color name="black">#000000</color>
    <color name="gray_70">#EEEEEE</color>
    <color name="gray_410">#979797</color>
    <color name="crimson_red" type="material">#CF2A2A</color>
    <color name="yellow_ocher" type="material material-accent">#DF9527</color>
</resources>

throws

Unhandled exception:
FormatException: Invalid radix-16 number (at line 2, character 2)

Not sure what I'm doing wrong here or if it's a legitimate bug 🤷

Relevant a pubspec.yaml.

Thank you for reporting. I will check it.

@DJTB DJ
Can you tell me your Flutter and Dart versions?

[DJTB]

I'm not sure since I didn't keep this repo around.
It was created with https://pub.dev/packages/very_good_cli.

I am currently on:

Flutter 3.3.10 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 135454af32 (3 weeks ago) • 2022-12-15 07:36:55 -0800
Engine • revision 3316dd8728
Tools • Dart 2.18.6 • DevTools 2.15.0

But I expect when I filed this bug I would have been using Flutter 3.3.8 and Dart 2.18.x

Happy to close this issue if you were unable to reproduce.
