[BUG] NoConfigFoundException

Unhandled exception:

✗ ERROR: NoConfigFoundException
No configuration found in flutter_launcher_icons.yaml or in pubspec.yaml. In case file exists in different directory use --file option

use the 0.11.0 version
i found that use
flutter_icons:
xxx
works!

this is because i view the source code 'flutter_launcher_icons_config.dart':
/// Loads flutter launcher icons config from `pubspec.yaml` file
static FlutterLauncherIconsConfig? loadConfigFromPubSpec(String prefix) {
try {
final pubspecFile = File(path.join(prefix, constants.pubspecFilePath));
if (!pubspecFile.existsSync()) {
return null;
}
final pubspecContent = pubspecFile.readAsStringSync();
return yaml.checkedYamlDecode(
pubspecContent,
(json) {
// todo: add support for new scheme https://github.com/fluttercommunity/flutter_launcher_icons/issues/373
return json == null || json['**flutter_icons**'] == null
? null
: FlutterLauncherIconsConfig.fromJson(json['**flutter_icons**']);
},
allowNull: true,
);
} on yaml.ParsedYamlException catch (e) {
throw InvalidConfigException(e.formattedMessage);
} catch (e) {
rethrow;
}
}
}

Start in flutter_launcher_icons_config.dart at loadConfigFromPubSpec and then inspect createIconsFromArguments in package:flutter_launcher_icons/main.dart around line 82. Reproduce the NoConfigFoundException with the 0.11.0 configuration shown in the issue and compare the supported configuration keys. Done means the reported configuration is recognized without the exception and icon generation proceeds.
