Time validation error on input when setting hour in flutter-CodePudding

Hi everyone I have some troubles with Flutter

Here is how I set my FormBuilderTimePicker widget

    FormBuilderDateTimePicker(
         name: 'fieldname',
         initialValue: DateTime.now(),
         initialDate: DateTime.now(),
         initialEntryMode: DatePickerEntryMode.input,
         alwaysUse24HourFormat: true,
         onChanged: (value) => mayValue = ,
         format: DateFormat.yMMMMd('it_IT').add_Hm(),
         timePickerInitialEntryMode: TimePickerEntryMode.input,
       )

The other input type is working fine, but I wout like to keep them both

CodePudding user response：

On flutter_form_builder: ^7.3.1 source code, alwaysUse24HourFormat has not being used. As matias-de-andrea mention on git issue which is still open.

To make it work, they override the transitionBuilder in order to provide 24h format on showTimePicker context.

transitionBuilder: (BuildContext context, Widget? child) {
    return MediaQuery(
      data: MediaQuery.of(context)
          .copyWith(alwaysUse24HourFormat: true),
      child: child!,
    );
  },

You can check How to use 24 hour clock when invoking showTimePicker() in Flutter? and they've discussed more about this.
