推荐答案
检查flutter_cupertino_date_picker库.date_picker_theme.dart文件具有以下代码.
check flutter_cupertino_date_picker lib. date_picker_theme.dart file have Below Code.
class DateTimePickerTheme with DiagnosticableMixin {
}
在Flutter 2.0版本中，它们删除了falvor DiagnosticableMixin.因此，请使用Diagnosticable删除DiagnosticableMixin.按照以下代码更改date_picker_theme.dart文件.
In Flutter 2.0 version they remove falvor DiagnosticableMixin. so remove DiagnosticableMixin with Diagnosticable. change date_picker_theme.dart file as per below code.
class DateTimePickerTheme with Diagnosticable {
}
