RemoveCurlyBracesFromTemplate - Intellij Community

Reports usages of curly braces in string templates around simple identifiers.

Use the 'Remove curly braces' quick-fix to remove the redundant braces.

Examples:

fun redundant() {
     val x = 4
     val y = "${x}" // <== redundant
  }

  fun correctUsage() {
      val x = "x"
      val y = "${x.length}" // <== Ok
  }

After the quick-fix is applied:

fun redundant() {
     val x = 4
     val y = "$x"
  }

  fun correctUsage() {
      val x = "x" <== Updated
      val y = "${x.length}"
  }
