Arguments

  • map (Map<String, dynamic>): The map you want to get value from.
  • path (String): The path of the property to get.
  • converter (T Function(dynamic)?): The function to cast the value to a custom type

Returns

  • <T>|null: Returns the resolved value or null if the path is not found.

Map map = {'a': {'b': 1}, 'c': '0xFFB74093'};
var b = gato.get(map, 'a.b');
var b = gato.get<int>(map, 'a.b');

Color color = gato.get<Color>(map, 'c', converter: (value) => Color(int.parse(value)));

Set #

Map<String, dynamic> set<T>(Map<String, dynamic> map, String path, T value)

Arguments

  • map (Map<String, dynamic>): The map to modify.
  • path (String): The path of the property to set.
  • value (T): The value to set.

Returns

  • Map<String, dynamic>: Returns updated map.

Map map = {'a': {'b': 1}};
map = gato.set(map, 'a.b', 2);
or
map = gato.set<int>(map, 'a.b', 2);

Unset #

Removes the property at path of map.

Map<String, dynamic> unset(Map<String, dynamic> map, String path)

Arguments

  • map (Map<String, dynamic>): The map to modify.
  • path (String): The path of the property to remove.
