Kotlin-style scope functions for non-nullable types.

These extensions bring Kotlin's popular scope functions to Dart, enabling concise transformations and side effects without intermediate variables.

final formatted = getUserName()
  .let((name) => name.toUpperCase())
  .also((name) => print('Processing: $name'));
