Deep dives
Unified Animation APIs in Compose
Compose animation APIs are designed to be more unified compared to previous frameworks. High-level APIs like animated content and animated visibility allow easy implementation of common use cases, such as fading or sliding elements in and out. However, while these APIs are user-friendly, they contain built-in assumptions that may not cater to more specific customization needs. For those advanced scenarios, developers are encouraged to utilize lower-level APIs for greater flexibility, despite their more complex setup requirements.
