MapExtensions<K, V> extension

Extension methods on Map for safe nested value access and deep merging.

final map = {'user': {'name': 'Alice', 'address': {'city': 'Paris'}}};
map.getPath<String>('user.address.city'); // 'Paris'
map.getPath('user.address.zip');          // null

Available on Map<K, V>, provided by the MapExtensions extension

Recursively merges other into this map, returning a new Map.

getPath<T>(String path) → T?

Available on Map<K, V>, provided by the MapExtensions extension

Navigates a dot-separated path into nested Maps and returns the value at the leaf.

tryBool(K key) → bool?

Available on Map<K, V>, provided by the MapExtensions extension

Returns the bool value for key, or null if absent or not a bool.

tryDouble(K key) → double?

Available on Map<K, V>, provided by the MapExtensions extension

Returns the double value for key, or null if absent or not a double.

tryGet<T>(K key) → T?

Available on Map<K, V>, provided by the MapExtensions extension

Type-safe typed accessor that returns the value for key if it is of type T, otherwise null.

tryInt(K key) → int?

Available on Map<K, V>, provided by the MapExtensions extension

Returns the int value for key, or null if absent or not an int.

tryList<T>(K key) → List<T>?

Available on Map<K, V>, provided by the MapExtensions extension

Returns the List<T> value for key, or null if absent or not a List<T>.

tryMap<K2, V2>(K key) → Map<K2, V2>?

Available on Map<K, V>, provided by the MapExtensions extension

Returns the Map<K2, V2> value for key, or null if absent or not a Map<K2, V2>.

tryString(K key) → String?

Available on Map<K, V>, provided by the MapExtensions extension

Returns the String value for key, or null if absent or not a String.
