Composer

Kotlin |Java

interface Composer

androidx.compose.runtime.Composer

Composer is the interface that is targeted by the Compose Kotlin compiler plugin and used by code generation helpers. It is highly recommended that direct calls these be avoided as the runtime assumes that the calls are generated by the compiler and contain only a minimum amount of state validation.
