What does .userData([android:"true"]) convey in ktlint('0.43.2').userData([android: "true"])

Question

ktlint('0.43.2').userData([android: "true"])

is a statement in spotless.gralde on using spotless with ktlint. I would like to know what is being conveyed when we give android:"true" in userData.

kotlin {
    target '**/*.kt'
    trimTrailingWhitespace()
    indentWithSpaces()
    endWithNewline()
    targetExclude("$buildDir/**/*.kt")
    targetExclude('bin/**/*.kt')

    ktlint('0.43.2')
            .userData([android: "true"])
}
