@irwancannadys Please add logs here too, so that I can identify what went wrong in your device. Also please mention the library version you are using. You can find library version in your project's pubspec file.

By using example project, I can reproduce the error by adding 2 lines below before runApp :

Intl.defaultLocale = 'id_ID';
await initializeDateFormatting(Intl.defaultLocale);
