A short talk that introduces SavedState's KotlinX Serialization support. I would like to show the new APIs, how to migrate from Parcelable/Bundle to Serializable/SavedState, and things to consider when deciding whether to migrate. * Key takeaways and learning points: - Learn the new APIs from SavedState. - Understand how SavedState saves all kinds of data under the hood. - Gain insights on when to keep using Parcelable and when to embrace @Serializable.
