检查 flutter_cupertino_date_picker 库。date_picker_theme.dart 文件有以下代码。

 class DateTimePickerTheme with DiagnosticableMixin {
  }

在 Flutter 2.0 版本中，他们删除了 falvor DiagnosticableMixin。所以用 Diagnosticable 移除 DiagnosticableMixin。按照以下代码更改 date_picker_theme.dart 文件。

  class DateTimePickerTheme with Diagnosticable {
  }
