toMapSignal method
Converts this map to a reactive map signal.
The resulting MapSignal provides reactive access to map operations and automatically notifies subscribers when the map changes.
Returns: A new MapSignal containing this map as its initial value
Example:
final userMap = {'name': 'Alice', 'age': 30}.toMapSignal();
Effect(() => print('User: ${userMap['name']}'));
userMap['name'] = 'Bob'; // Triggers effect: "User: Bob"
Implementation
MapSignal<K, V> toMapSignal() => MapSignal(this);
