Invalid argument exception in String.convertName if the name consist of more than 3 part (contains more than 2 underline)

I run this (with i18n: ^3.4.0):
flutter pub run build_runner build --delete-conflicting-outputs --verbose
and get this error :
[SEVERE] i18n:yamlBasedBuilder on lib/utils/localization/appLocalization.i18n.yaml:

Invalid argument(s):
package:i18n/src/i18n_impl.dart 21:7 FirstUpper.convertName
package:i18n/src/i18n_impl.dart 185:33 renderTranslation.

package:i18n/src/i18n_impl.dart 82:5 generateDartContentFromYaml
package:i18n/builder.dart 22:23 YamlBasedBuilder.build

The argument was "Location_permission_disabled_screenAppLocalization".
It is from appLocalization.i18n.yaml :
location_permission_disabled_screen:
