Issue Regarding Alarm List

[himanshu717171]

Target of URI hasn't been generated: 'alarm_list.g.dart'.
Try running the generator that will generate the file referenced by the URI.

This is the error showing on alarm_list.dart and few more pages like alarm_status.dart, searchable_selection.dart.
I don't understand why in my PC "part 'searchable_selection.g.dart';" like this packages are not working..

Please solve this issue

Have you tried doing what the error tells you?

Try running the generator that will generate the file referenced by the URI.

-> Run flutter packages pub run build_runner build --delete-conflicting-outputs to generate the .g.dart files.

Both mobx and json_serializable rely on generated files that are created based on annotations within the code.
You can find more information on those two packages on the respective pub.dev pages: json_serializable and mobx_codegen.
More information on the build_runner and why it's used can be found on the build_runner package page.

I can highly recommend following the advice in the error message once again:

Please try upgrading to the latest analyzer by running flutter packages upgrade.

In general Flutter provides developers with extremely detailed errors explaining cause and potential solutions.
