You can modify the DiagnosticMixin in the library to Diagnostic

[mzkai]

After the most recent Flutter update, changing 'DiagnosticMixin' to 'Diagnostic' indeed solves the problem. Thanks @jacky-yanglei!

The flutter_datetime_picker package should now be updated with the same.

[jayaike]

I had this issue too but it was solved by @jacky-yanglei 's suggestion. Thanks

Will this be released in a V.1.3.9 any soon? I am having issues as well.

DiagnosticMixin in the library to Diagnosticable, not Diagnostic

For me I replace all DiagnosticableMixin in the class by Diagnosticable and it works

FYI there is a PR to fix this. You can use it now by putting this in your pubspec.yaml

 flutter_datetime_picker:
   git:
     url: https://github.com/ditheshthegreat/flutter_datetime_picker # Repo
     ref: patch-1 # Branch name

pr-> #158

Thank you, this helped get my build running after the recent flutter updates that just broke nearly everything and this was the last thing to get it going.

[Realank]

Done

[fnicastri]

Done

@Realank
Thanks!

This update in pubspec.yaml solved my problem.
flutter_svg: 0.18.1
flutter_html: 1.0.2
flutter_widget_from_html: 0.4.3

Don't forget to do flutter clean after the update

[shinriyo]

@the-anup-das

Flutter_svg? Not flutter_svg?

dnfield/flutter_svg is needed?

it works for me.

dependencies:
  flutter_datetime_picker: ^1.4.0

Yeah you are right! thanks for seeing it.

If you are rendering SVG or XML files you will need flutter_svg

It is not recommended if you don’t know what you are doing.
Search and replace the name of the class and it will works
