Solved ! As can be seen in screenshots that there are some errors of packages (flutter_local_notifications - modal_bottom_sheet )

1 - I deleted cache folder in C/$user_name/AppData/Local/Pub

2 - Updated all packages manually including flutter_local_notifications

3 - Added under dependency_overrides this package

modal_bottom_sheet: git: url: https://github.com/danReynolds/modal_bottom_sheet.git path: modal_bottom_sheet

4 - run flutter clean

5 - run your project successfully

As can be seen in your linked screenshot, there's an issue with how flutter_local_notifications uses a wrong signature for a class from flutter_local_notifications_platform_interface. This is probably a result of invalid version constraints made by the developer in the 10.0.0-dev.1 prerelease version that you're using.

I would recommend updating the flutter_local_notifications to the latest version (as of the time I'm responding is 13.0.0).

If you can't do that, you can at least update to a stable version. The one you're using is a prerelease version according to semantic versioning. Try version 10.0.0.

It didn't work also. as there is problem with flutter_local_notifications also there is problem with modal_bottom_sheet , but i'm confused about these errors .

I think this has no relation with packages themselves may be there is a conflict or something like that.

You also need to fix the other problem then, too. The kernel_snapshot failure is just a tool failure that results from the Dart compilation failures
