Null-safety migration

[themisir]

Fixes #37

[themisir]

Actually I think nnbd version should be maintained separately on different branch for some time. At least that's what we did when migrating hive to nnbd.

Hello @themisir! Thanks for doing this work :)
Ping me when you have finished this PR 🙂

[themisir]

@curquiza it's ready. Just updated pubspec.yaml version to v0.2.0 and tests are passing (if dart >2.12).

[curquiza]

Thanks a lot @themisir 😄

• Can you update the bors.toml file please? Some tests have to be removed 😇
• Does the README need changes? I think about the Getting Started section

[themisir]

• Can you update the bors.toml file please? Some tests have to be removed 😇

I've updated bors.toml because testing null safety requires dart ^2.12.

I've updated bors.toml because testing null safety requires dart ^2.12.

My bad, I miss checked! :)

[curquiza]

Awesome!! 🔥 Thanks @themisir!

bors merge

[bors]

Build succeeded:

• integration-tests (dart 2.12)
• linter-check

@curquiza out of context, but what does bors exactly?

[curquiza]

TLDR: Bors is a tool that applies a rebase before running the tests and finally merging if they succeed.

To be more accurate, Bors does not concretely rebase the branch of the PR: it merges the commits of the PR into another branch (staging) that is already up-to-date with main. If the tests do not pass on the staging branch, Bors returns a failure and stops the merge of the PR.

We use it because:

• we don't have to ask the contributors to rebase anymore which is a really nice point 😁
• it can handle multiple PRs at the same time: no need to wait for the PR of your colleague to be merged to merge yours.

I wrote a guide about it here: https://github.com/meilisearch/integration-guides/blob/main/guides/bors.md
Also, I wrote an article about our usage of bors, but it's not released yet 😇

Also, bors is a tool widely used (and created) by the rust community

Thanks 🙏
