Generates builder classes for data classes, enabling map-like property access and building. Features type-safe code generation, reflection support, and null-safety for optional properties.
A Kotlin Symbol Processing (KSP) plugin that generates builder classes for Kotlin data classes. The generated builders allow you to get and put properties in a map-like way and finally build a new instance. Supports both JVM and Android platforms.
