        .contentMargins(0)
        .padding(0)

}

Right here in UserDefaults I do not get metropolis, nonetheless in my Flutter app I replace this information. I initialize residence widget at predominant dart, after which

HomeWidget.saveWidgetData<String>(
      'metropolis',
      metropolis,
    );

replace my metropolis.

In android every thing works good. I get knowledge. However in iOS there’s some drawback. I believe the issue is with swift code. Thanks upfront for assist.
