@rt4914 @BenHenning PTAL

[Sarthak2601]

Hey @soamOne, please have a look at the domain tests. It seems like they are failing. Also, PTAL at this guide for PR submissions.

[rt4914]

@soamOne Thanks for creating this PR.
Couple of points to take care of:

1. Update your number-input-package branch with latest develop. Currently this branch is behind develop.
2. In the Description of PR, please mention details like:

Hey @Sarthak2601 @rt4914 @BenHenning PTAL now.

[Sarthak2601]

LGTM. Thanks @soamOne !

[rt4914]

LGTM, thanks.

[soamOne]

Thanks

[BenHenning]

Thanks @soamOne.

These files ought to go under numericinput not numberinput for parity with the other package names & for consistency with the interaction name. Also, it looks like the Bazel files weren't updated which is causing a build breakage for Bazel tests. See: https://github.com/oppia/oppia-android/blob/74db288/domain/BUILD.bazel#L64.

[soamOne]

@BenHenning I will look into it and fix it, thanks.

[BenHenning]

Also I just realized that the original package was never updated to match the new directory structure. This is actually a case where Gradle misbehaves: it (incorrectly) doesn't require directory structures to match their directory structures, but Bazel does. Given that the build isn't actually broken, I won't revert this PR, but we should prioritize fixing that since it can lead to confusion.

Thanks @soamOne!

[soamOne]

Okay, so what all needs to be done now @BenHenning ?

[BenHenning]

@soamOne see #1882 (comment). Does that help?

[soamOne]

Yes @BenHenning, got it.
Thanks!

Hey @BenHenning, a couple of questions:

1. Can org/oppia/domain be deleted now?
2. Should I open a new pull request?

[rt4914]

@soamOne

1. You just need to take latest pull from develop and checkout from that to create a new branch. That should fix the issue related to your first question once you shift the files.
2. Yes you can create a new PR.

[soamOne]

@rt4914 okay, got it.
Thanks!
