Firebase Dynamic Links Lifetime

I'm using Firebase dynamic links to share links with some parameters between users. For now, I am using only an Android version, but I plan to extend my app to support iOS version.

I'm asking for help about:

• how long is the lifetime of Firebase dynamic links?
• what do you suggest me, should I store generated link to my database and later share it between users or generate a new link on every share (users can share the link for a same set of parameters several time, not only one time)

Thanks

1. Dynamic Links don't expire

2. I generally prefer adding a new link every share. It means you can do things like easily change or A/B test some of the parameters around the link (like the social sharing settings). It does mean you have to make a network call every time, but I guess the same would hold true for keeping your link in the database. For more info, you might want to check out this video. (It's for iOS, but a lot of the principles are the same)
