Required property is not set if field is conditionally required

[sasmangulyan-vineti]

Describe the bug
When making the specific field required based on some condition the required property is still false.

To Reproduce
Steps to reproduce the behavior:

1. Schema contains something conditional
   { type: "object", properties: { b: { type: "boolean" }, c: { type: "string", minLength: 1 } }, if: { properties: { b: { enum: [false] } } }, then: { required: ["c"] } }
2. When making the "b" from true to false (for example checking and unchecking the box), required property of ''c'' which has the renderer of MaterialInputControl will not be changed and will remain false.

Expected behavior
After a conditional action the required property of MaterialInputControl to become true.

Thank you for your report.
I just double checked, the if/then/else is working fine.
We don't set the required property at all in the renderers.
I adapted the title because of this.

We happily would accept a contribution for this.

Hey @eneufeld @sdirix, I see this has been moved to the backlog, are there no plans to fix this soon? Having it in would be a big win for me 👍🏻

@stevenmckinnon In general I think setting the required prop as suggested by you in #1695 is a good idea and we should implement it in one of the next versions (i.e. next), however it's not on our priority shortlist. You're welcome to open a PR to fix the issue, and we'll definitely have a look at that.

The requested feature here relates to if/then/else and will be much harder to support. As the use case is rather niche we have no plans to support this in the near future. If you'd like to contribute this feature we should discuss how the optional required can be detected and evaluated efficiently.

In case you need a solution for right now you can always just write your own custom renderers which set the required prop appropriately.

You might also be interested in our support packages which includes prioritization and development of requested features.
