Crash with R8 minification and DateTimeFormat

[prof18]

Hi,

I've run into the same issue as mentioned in: #402, while trying to update to new AGP my project (https://github.com/prof18/feed-flow/tree/date-time-r8-issue)

I've build up an easier reproducer, you can find it here: https://github.com/prof18/DateTimeR8IssueRepro.

(I've opened a new issue, as I'm not sure if the old closed one will be noticed)

Thanks!

It works by keeping DateTimeComponents

-keep class kotlinx.datetime.format.DateTimeComponents { *; }
