kt property
      
      KtMutableMap<K, V> 
      get
      kt
      
    
    
Wraps this Map with a KtMutableMap interface.
In most cases you don't want mutability. Use toImmutableMap instead.
Mutations on the KtMutableMap are operated on the original Map.
Implementation
KtMutableMap<K, V> get kt => DartMutableMap.noCopy(this);
