Convert to primary constructor

Last modified: 03 December 2024

Reports a secondary constructor that can be replaced with a more concise primary constructor.

Example:

class User {
    val name: String

    constructor(name: String) {
        this.name = name
    }
}

The quick-fix converts code automatically:

class User(val name: String) {
}
