attach<T> method

T attach<T>(
  1. T value
)

Attaches a contextual value to this instance and returns the value. The type of T is the signature/key, attaching more than one thing of the same will only store the last one.

Implementation

T attach<T>(T value) {
  final key = T.runtimeType.toString();
  _context[key] = value;
  return value;
}
