Locale data has not been initialized, call initializeDateFormatting(<locale>) #22

Closed yagizdo closed 8 months ago

yagizdo commented 9 months ago

I am encountering a sporadic issue with locale settings in my Flutter application. Specifically, the application throws an error related to locale settings whenever I try to set the locale to anything other than the default.

This error occurs with various locales (tr, ar, etc.), including attempts to set the locale explicitly to English (en or en_US). Interestingly, the issue temporarily resolves itself without any changes on my part, only to reappear later under the same conditions.

Package version : easy_date_timeline: ^1.0.4 Flutter Version: Flutter 3.16.5 Dart Version: Dart 3.2.3 Test Simulator: iPhone 13 - iOS 15.0

Error :
