Call of 'toString' could be replaced with string template

Reports toString function calls that can be replaced with a string template.

Using string templates makes your code simpler.

The quick-fix replaces toString with a string template.

Example:

  fun test(): String {
      val x = 1
      return x.toString()
  }

After the quick-fix is applied:

  fun test(): String {
      val x = 1
      return "$x"
  }
