ReplaceWith(expression: String, vararg imports: String)

Specifies a code fragment that can be used to replace a deprecated function, property or class. Tools such as IDEs can automatically apply the replacements specified through this annotation.

expression

val expression: String

the replacement expression. The replacement expression is interpreted in the context of the symbol being used, and can reference members of enclosing classes etc. For function calls, the replacement expression may contain argument names of the deprecated function, which will be substituted with actual parameters used in the call being updated. The imports used in the file containing the deprecated function or property are NOT accessible; if the replacement expression refers on any of those imports, they need to be specified explicitly in the imports parameter.

imports

vararg val imports: Array<out String>

the qualified names that need to be imported in order for the references in the replacement expression to be resolved correctly.
