toString method

  1. @override
String toString()
override

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  switch (_value) {
    case 0:
      return 'FileSystemOp.read';
    case 1:
      return 'FileSystemOp.write';
    case 2:
      return 'FileSystemOp.delete';
    case 3:
      return 'FileSystemOp.create';
    case 4:
      return 'FileSystemOp.open';
    case 5:
      return 'FileSystemOp.copy';
    case 6:
      return 'FileSystemOp.exists';
    default:
      throw StateError('Invalid FileSytemOp type: $this');
  }
}
