Upgrade dart to use nnbd.

[yuzurihaaa]

Time to give dart 2.10 a try.

[TomerPacific]

@zaralockheart , I'd like to help. Is all that is needed to do in this issue is to upgrade the dart version?

[yuzurihaaa]

Hi @TomerPacific , thanks for willing to help! I created issue for me to track down what I plan for this repo (also to help out fellow hacktoberfest) yeah, upgrade, and maybe to also refactor the codes into nnbd style. I haven’t give that a try yet, so I am assuming it will take more than the change in pubspecs.yaml 🙂

[TomerPacific]

@zaralockheart , got it. I'm not familiar with NNBD, but I'll keep you updated on what I am trying to do.

[TomerPacific]

@zaralockheart, from reading online a bit, I found this SO question which pointed to this NNBD migration tool. Might be worth looking into.

Would you like me to try and use this migration tool?

Also, I am getting this error when trying to perform pub get:

Because hive_generator >=0.8.0 depends on analyzer >=0.40.0 <2.0.0 and mockito 4.1.2 depends on analyzer ^0.39.15, hive_generator >=0.8.0 is incompatible with mockito 4.1.2. And because no versions of mockito match >4.1.2 <5.0.0, hive_generator >=0.8.0 is incompatible with mockito ^4.1.2. So, because data depends on both mockito ^4.1.2 and hive_generator ^0.8.1, version solving failed.

@TomerPacific Hi, yeah sure, you can use the tool to ease out the migration, there's no hard requirement here :) I think those are due to data domain/ pubspec.yaml files. Maybe override_dependency could help there.

[TomerPacific]

@zaralockheart , got it working by adding : dependency_overrides: hive_generator: ^0.8.0 mockito: ^4.1.1

When trying to run the dart migrate command, there are many dependencies which need to be updated or are either incompatible.

It is highly recommended to upgrade all dependencies to versions which have migrated. Use `dart pub outdated --mode=null-safety` to check the status of dependencies.

When trying to perform pub upgrade without the dependency_overrides, it fails. If I add the dependency_overrides, it doesn't manage to successfully update all dependencies.

Sry, was quiet busy recently. Aww, this doesn't looks fun :(

I haven't look into NNBD yet, but maybe I can look into it deeper when I have the time. Is this related to this warning https://github.com/dart-lang/sdk/issues/41712 ?

[TomerPacific]

@zaralockheart , I don't think so. I think it has to do with the different packages you have in this project, their inner dependencies and the fact that some of them don't have a version that supports NNBD. What would you like me to do with this issue?

[yuzurihaaa]

I guess, I'll take stuff that you've done, and will keep this open for future exploration. 🙏🏻 Thanks for the help! I didn't expect anyone would come to this repo actually 😅

[TomerPacific]

Always glad to help. Do you want me to open a PR for anything? I basically changed the version in pubspec.yaml and upgraded various packages.

[yuzurihaaa]

Any PRs are welcomed :)

[TomerPacific]

@zaralockheart , I have opened a PR. I would appreciate it if you would add the hacktoberfest-accepted label to it.

[yuzurihaaa]

Thanks @TomerPacific for the help :)

[yuzurihaaa]

Reopen for self track, maybe the feature will me much for stable for the other packages to migrate to use it.
