[TS] Support default values for strings

[abhay-agarwal]

Typescript doesn't use a special flatbuffers string type as far as I can tell, so in the deserialization code for a table, it seems trivial to return a default string if provided instead of null. This would allow for string and vector defaults in the generated code.

We use flatbuffers across Rust, Swift, and Typescript. The lack of support for this in TS is the only issue blocking adoption of default string values for us.

Let me know if interested in having a PR submitted for this issue

Wasn't aware this wasn't already supported, sounds like a good idea to fix.

[abhay-agarwal]

Sounds good I can take a crack at it but it'll be my first contribution so let me know if there’s anyone who can implement it faster / more effortlessly.

@abhay-agarwal I wouldn't worry about needing it done quickly 😅 take your time and we welcome new contributors!!

Hey I've submitted a PR for this fix a few weeks ago, is it possible to approve the workflow run on it so I can tell if it will pass checks?

[jtdavis777]

Done!

[abhay-agarwal]

Great, so the PR passes checks. What are the next steps? It is possible this PR will have some significant conflicts with another TS PR that seems to be close to finalization. Anything I can do to move things along given this?
